After importing an existing project into RubyMine, I encountered "Rails server launcher wasn't found in the project" when I Run/Edit Configuration.
I've checked this Cannot start the debugger in Rubymine. Rails server launcher wasn't found in project, but deleting the .idea directory and re-open is not helpful.
I can rails server in the Terminal successfully and the rails server runs. So I guess it's likely a RubyMine related thing.
Thanks,
Allen
The easiest way to fix it:
Close project
Remove .idea folder from project folder
Open project
Bingo!
NOTE: this workaround seems to no longer work with 2017.2. See RUBY-20144
I upgraded from RubyMine to IntelliJ Ultimate IDE 2017.1.5 and I encountered the same error "Run Configuration Error: Rails server launcher wasn't found in project". I was using Ruby v2.4.0 with Rails 5.0.2.
It took me an entire day to solve the issue, so I've written a detailed explanation with screenshots to guide others.
It occurred when I tried to Run or Debug my Rails server from within IntelliJ.
Other solutions also didn't fix the error. I tried deleting my .idea/ folder, trying different Ruby or Rails versions (i.e. Ruby v2.3.0 or latest Rails 5.1.2), and even starting a brand new project from scratch. But I could run the Rails server fine using Terminal (outside the IDE) with rails s.
SOLUTION approach:
First I opened Run > Edit Configurations but "Choose SDK from module" didn't have any Project Modules available to select from the drop-down, so I had to create one as follows:
I went to File > Project Structure
Then I clicked Modules, and clicked the icon "+", and selected "Import Module".
Then I navigated to my Rails project's root directory "'/Users/my_username/code/apps/_murmur/skag_server_rails" and clicked Open, which displayed the following.
I then selected "Create module from existing sources" and clicked "Next", and it showed the following, with a blue checkbox shown next to my Rails project root directory that it found, so I clicked "Next" again:
It then showed the following window, and I clicked "Finish".
I'd now finished importing the Rails project I was working on as a Module, and it showed the following, so I clicked "Ok", as I was now ready to try and run my Rails server again:
So I went back to Run > Edit Configurations window and click on "Rails > skag" where I could now use "Choose SDK from module" since there was now my "skag_server_rails" Module available in the drop-down that I just created, and no errors were apparent, as shown below:
I was then able to click Ok to save the Run/Edit Config
I was then able to run the server Run > Run, which displayed:
I was then able to successfully open the Rails app in the browser open http://localhost:3000
But then when I tried to Run > Debug so I could debug using breakpoints, it gave me the following errors:
I solved this by running the following in the Terminal (outside the IDE):
gem install debase --pre
gem install ruby-debug-ide
Then finally I could run Run > Debug and it allowed me to trigger breakpoints as shown below:
Important Note:
The initial approach that I took that DID NOT end up fixing the error involved choosing to use "Use other SDK" within the Run > Edit Configurations window to load my Ruby Gemset into the debug configuration (instead of using a Module).
UPDATE: I encountered the same error again more recently on 2nd September 2017 and followed these steps to overcome it:
Go to Menu > File > Project Structure > Project Settings > Modules > Click "+" and select "New Module"
Select "Ruby on Rails" from the left hand side list
Choose for "Module SDK" label your "RVM: ruby-2.4.1 []"
Click for "Rails Version" label the "Install Rails Gem..." drop-down
Select a Rails version for it to download and wait (i.e. 5.0.0)
Do not select a Rails version that causes the tooltip "This version is not fully supported" to appear below (i.e. selecting a Rails version >5.1.2 causes this to occur)
Click for "Rails Version" label the version that finished downloading from the drop-down (i.e. 5.0.0)
Enter "Working Directory" label value of "../"
Enter a "Module Name" (i.e. videotube-5.0.0)
Click "Apply" and "Save"
Go to Menu > Run > Edit Configurations
Change any directories that do not point to root folder of app
Go to Menu > Run > Debug
My variant to solve same problem.
Create new run configuration, but use "Ruby" template instead of "Redmine":
Ruby script field set to path to your redmine rails bin path and Script arguments set to "server -b 127.0.0.1 -p 3000 -e development" for ex.
This worked for me
Remove the .idea file
Invalidate the cache and restart the ide
Ok, this RubyMine has some serious issues. My day started out peaceful and then ended as a nightmare, courtesy of RubyMine. All I did was git checkout to a certain version of my repo. Well, when I did that, suddenly the folders in RubyMine disappeared. Yes, that is the first bug. I git checkout 8d4fbd1b5dfce0a3daa16896a603903a And then I open RubyMine and folders are gone! I closed and reopened. Still no folders. I restarted computer and still no folders.
I had to go to Project > File Structure and delete the Module. And then create a new Module. Now the project folders appear. But then I get this obscure error Rails server launcher wasn't found in the project. I have no idea what it means. I go online and they say delete .idea directory in your project. So I do that. And now again I have to delete and recreate the module.
This time it says "overwrite directory" since I have an existing project. I select "Yes" and then I open project and my secrets.yml is gone! Now I had to use secrets.yml I had backed up. And then finally it works.
Seriously, all this just because I wanted to checkout out a specific git commit? Come on.
UPDATE
After further investigation, I understand what is going on. There are three critical Intellij Idea files with regards to the Ruby plugin:
/.idea/
MyProject.iml
/MyProjectGemset/
These three files should not be checked into git and should be consistent across the different branches of your project. You might have another *.iml in the project. Delete that and make sure you are using the same .iml throughout the branches.
These two files pertain to your SDK:
MyProject.iml
/MyProjectGemset/
This file pertains to general configuration:
/.idea/
I've came across this same problem, and a way I found to solve it was to properly defining the root folder of the project when opening it in the first time with RubyMine.
As far as I can understand, ideally you should open the project by pointing the RubyMine to the project's root folder:
my-workplace/
|-- rails-project-name/ <-- point RubyMine here when openning
| |-- app/
| |-- bin/
| |-- config/
| |-- db/
| |-- lib/
| |-- log/
| |-- public/
| |-- test/
| ...
if you follow the solution from Artyom Blagoda on the Windows with ruby installed on the WSL (Ubuntu) you'll get into situation when wsl path (\wsl$\Ubuntu) of ruby script (rails) could not be found by remote (Ubuntu) ruby interpreter. to make it work you need to add path mapping on:
Settings -> Ruby SDK and Gems -> Your remote ruby or RVM -> then click the folder icon above, you'll find a new window where you put:
Local Path: //wsl$/Ubuntu/PATH_TO_YOUR_RAILS_BIN
Remote Path: PATH_TO_YOUR_RAILS_BIN
hope it helps ;)

I'm using Aptana Studio 3 on Mac OS X (High Sierra). I have imported my Ruby on Rails project. My Project Natures are set up like this
I want to set up my Rails server so I can run it from the IDE (or debug with it). Oddly, the Run/Debug settings only include PHP ...
So how do I create a run configruation to run my server? When I right click my project, select "Run As" -> "Run Configurations", I see a screen like this. Not sure if this is the right screen to configure things or how to do it ...
You can run your server creating a run configuration or just creating a new Rails Server.
Creating a Run Configuration
In "Run Configurations" options, select Ruby Applications > New_configuration and then click in "Browse...". Type 'rails' to search for the rails file and select it inside "Matching resources". Click "Ok".
Then go to Tab "Arguments", set the working directory as the root folder of your project, and inside "Program Arguments" put the value "server" and click "Apply".
Now you can run or debug your application.
Creating a Rails Server
Go to Windows > Preferences > Aptana Studio > Web Servers and click in "New...".
Then select the option "Rails Server", choose the name of your server and click "Ok". If your project nature was not set to "Rails" the option "Project" would be empty here, and you would need to set the Rails nature first.
If you try to run the server like this you will receive an error telling that the program ".../script/rails" does not exist, so first you need to create a folder named "script" inside your project and paste the file "bin/rails" inside it (as explained here).
Now just click with the Right mouse button in your project and select "Run server".
I've been using this guide
Whenever I go to import the module I get this screen:
I used the following file path, maybe this is whats wrong?
/usr/local/Cellar/ruby-build/20160130/share/ruby-build/2.3.0
And got this error:
I'd appreciate any ideas anyone might have, i've been trying get this working all night!
I ran into this problem with Intellij IDEA 2020.2. It took a while to resolve because the Intellij documentation seems to be missing one critical piece.
When you first open a project in IDEA, it assumes all your code is part of a Java module. With that module in place you cannot set a Ruby SDK at the module level. There's no option to do because the existing module is configured as Java.
Here's a screenshot of my example project with the default Java module. Notice the icon is a folder with a blue rectangle in the lower, right corner.
Here's what I had to do.
Open the Project Structure dialog (File | Project Structure).
In the Modules settings, highlight the top-level project module and click the delete button (looks like a minus sign).
Click the plus sign to add a new module.
From the pop-up click "New Module".
In the "New Module" pop-up select Ruby and the correct Module SDK (e.g. rbenv: 2.5.0)
When you are prompted to enter the Module name, Content root, and Module file location, make sure the directories are set to your project's root. When I entered the module name it appended the name to the project's root directory which is probably not what you want.
Once you've done that the module should appear with a Ruby icon on it and the rest should work as documented here: https://www.jetbrains.com/help/idea/configuring-language-interpreter.html
Here's a screenshot of my new Ruby module. You can see the Ruby icon replaced the blue rectangle.
I hope this saves you some time!
In order to set Ruby SDK for your project in IDEA you need to go to File | Project Structure | Project Settings and set project and module SDK.
Olivia is correct, the "Project Structure..." (Mac shortcut Cmd+;) is the dialog for configuring the IDE to use different ruby installations.
The first requirement is that the ruby manager (chruby, rbenv, rvm) is configured properly.
Another concern is exactly where and how jetbrains expects the ruby installation to be organized. I wonder if Intellij is compatible with the way ruby-install lays out ruby? That's the one I used with chruby. I could not make it work.
The posted url to Opening Rails projects in IntelliJ IDEA helped me feel the most confidence that we are on the right track. :)
At the time, I was failing to get Intellij configured due to fact the gem files were not seen by the IDE. All but about 4 gems in my project's Gemfile was being highlighted as having an SDK problem.
To end this, I stopped using chruby and ruby-install. I am not blaming chruby, however I could not make the chruby system work properly with the IDE. It worked fine in the shell. Note, I am a previous user of rvm and rbenv. Switching back to rbenv, now. Note that I've also stopped using ruby-build directly.
Instead, I built the first ruby version directly from rbenv:
rbenv install 2.3.1
Next, I created the .ruby-version file in the root of my rails project directory by running:
rbenv local 2.3.1
To help with any confusion regarding the minimum support needed in the shell startup scripts. Do not alter PATH at all. Place the following in your shell startup script system, whatever that may be:
# rbenv config in my .bash_profile
# --------------------------------
if which rbenv > /dev/null; then
eval "$(rbenv init -)";
fi
With the prerequisites out of the way...
I recommend doing the project import in the same way described in the jetbrains tutorial Opening Rails projects in IntelliJ IDEA.
In the first screenshot from thesowismine, I see two dialogs for different purposes that are simultaneously open. Unless I am mistaken, one of those dialogs should have received its info and closed before going forward, at least during the wizard-like process. Perhaps this was done and that dialog was reloaded later?
In any event, that is not where the Ruby SDK is associated to a Rails project. The screenshot indicates the User is browsing around the brew Cellar, which may indicate two things.
Ruby was installed with a brew install <version> command; I installed ruby by calling the rbenv ecosystem.
That particular dialog is for informing the IDE about the Rails project folder, not the Ruby kit.
Assuming the first dialog is provided with the root directory of the Rails app and next is clicked; then in the second dialog, I change nothing and click next. The 3rd dialog is where I confirm the project directory is correct and I can assign a more elaborate name (which is displayed in the IDE's project menu). Clicking next may prompt you to write over the ".idea/" directory. Say yes. The next dialog confirms that sources were found. Click next. Now Frameworks begin to be detected assuming the Ruby Manager is setup correctly. Click Finish.
Now, goto the "Project Structure..." dialog to set the SDK.
Before or after setting the SDK, go to the the project directory of your Rails project, run:
gem install bundle
bundle install
This will install all the gems your project requires including the rails gem, as presumably it is listed in your Gemfile.
Note that gemsets do not come up, here. In this config, the set of gems are associated to a particular Ruby installation. Bundler is your friend.

I was able to solve this by doing:

I'm just starting out with rails and I'm practicing the basic ruby commands, one of which is the rails new myproject command.
My projects are under the Aptana workspace directory where I've used the command line and Aptana both to create projects there. After a few creations and rails s commands and deletions, I've started getting this error message when I try to generate a new rails project:
"Can't initialize a new Rails application within the directory of
another, please Type 'rails' for help."
This doesn't just happen when I create a new project (rails new myproject) under the Aptana workspace directory, but also when I use the command rails new . directly inside the workspace directory. Can someone explain to me what I need to do to flush rails so it knows I don't have a project there anymore? What did I do to make this happen?
I don't remember what rails looking for. The quickest way to solve this issue is to completely empty the affected directory.
Most likely there are some hidden files or directories which prevents rails from creating a new project. Look at that with ls -a probably there is a .bundle folder inside that dir.
I got same problem since I failed to create rails project. I tried to remove Aptana plug-in and Eclipe that include ./eclipse, ./metadata but not sloved the problem until I removed Ruby and Devkit and reinstall them again.
So, I think the root cause may in Devkit or Ruby. The problem work out after I reinstall Ruby(rubyinstaller-2.2.3-x64.exe) and DevKit(DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe).
If you are under Windows, you must install Aptana Studio as administrator or it will not work properly. Uninstall and install it as administrator and the terminal folder will be set correctly
I just installed ruby on rails on my new computer ( I was using instantrails before) and I'm trying to get everything setup.
Im running Windows 7. So I followed the instructions from this tutorial.
http://blogupstairs.com/ruby-on-rails/installing-ruby-on-rails-on-windows-7/
The problem i'm guessing is step 3
"Add the newly installed bin directory to your path in your windows system : Open windows explorer-> right click the icon computer-> choose Properties -> in the contol panel Home, Click Advanced system settings and then click Envitonment Variables button->in the system variables click new and add new system variables like this : Variable name : RUBY_HOME , Variable Value : C:\Ruby, after that add it in to the path and add the bin after a semicolon to the “Path” variable like this : C:\Program Files\Common Files\Adobe\AGL;%JAVA_HOME%\bin;%ANDROID_HOME%\tools;%RUBY_HOME%\bin"
I set created the system variables but when I try to run script/generate in the main directory of my app I get the error
"Ruby: no such file or directory --script/generate"
I checked the apps directory and the script folder is in there. How can I run the "ruby script/generate" commands from the control panel?
I was guessing it was something with the path but I dont know any ways to check to find out whats going wrong.
Are you using Rails 3.0+? In this version of rails and up, the script/* folder has been deprecated in favor of rails generate, rails server, etc. See here.
In 99.99999% of all cases, if a computer tells you that it cannot find a file at a specific location, it is because that file is not at that specific location.
So, is there actually a file named generate in a directory named script in the current directory?
I have recently installed RoR on my "clean" Win7 as well.
What IDE are you using?
I suggest trying JRuby with NetBeans/RubyMine:
JRuby installer does all the work (even adds the proper variables to your path in system environment settings...,
IDEs take care of gems, setting up servers etc.
As for the commands, as Nuclearsandwitch mentioned, there is no script/generate or script/server in Rails 3. Just make sure you in the directory with your Rails app and then try running rails server. It should work :-)
I am using Windows 7 and Ruby 1.8.7. I get the following error message when I start a new Rails project:
Problem Occured
'Replace project index file' has encountered a problem. Resource '/Foobar/public' does not exist. (where 'Foobar' is the name of my new project).
Any ideas?
Just found a workaround: Create the project but UNCHECK the part about generating a rails skeleton. Then open a console, navigate to the project's parent directory, and run rails <project name>. The skeleton will generate in the folder, and then you can refresh the project directory within Aptana/Eclipse.
When new project is created using radrails, RadRails execute the command rails beta -d sqlite3 which is older syntax and the new syntax is rails new beta -d sqlite3 So unless the Aptana Teams invokes new rails functionality the workaround would be to use the methods mentioned above.
Follow the same procedure as mentioned above....
But for me Rails didn't work.
rails new "project name" worked for me.
Thanks
I had this problem because my project had spaces in the name. Removed the spaces and it worked.
I've the same problem but in web projects and using a network directory. I create the project in local and then move it to network unity.
Try running your IDE as an administrator. Right click your IDE icon -> "Run as administrator".
Now your IDE will have the appropriate privileges to write files and folders.
Changing the interpreter that the IDE uses worked for me. Go to windows->preferences->ruby->installed interpreters then select the one that comes with your installation of Aptana Studio, mine's name is org.jruby_1.2.0.9... It worked like a charm for me. I hope that helped.
