How can I start a rails project using a batch file?
I didn't see the command rails s has a path parameter to do that.
What I need to do is to pass an absolute path to my project and activate it by running this batch file.
thanks.
first move to the project location with cd then use rails server
Example:
cd "\Users\Joe\RoR\MyRailsApp"
rails server

I am trying to use netbeans 7.4 with Ruby 2.0.0-p353 and Rails 4.0.2. Plugin seems to work ok. I am able to generate project and everything is there, but when I try to run project I receive following message and server is not started:
C:\Ruby200-x64\bin\ruby.exe: No such file or directory -- script/rails (LoadError)
There is a comment under official plugin page that says:
I found a simple workaround, I'm using Windows 7 and created a
symbolic link between directories like this: mklink /D script bin
Now I can start and debug my Rails 4 project in Netbeans. Posted by

I have tried to do this but it still doesn't solve a problem. Is there anybody that can help?
The proposed solution works well from what I have seen. What is the error you are getting? Are you able to create directory link? You would need Admin rights for that and should start the command prompt "Run as Administrator". Alternatively, try right-clicking on the "bin" directory and execute "Create shortcut" that must be renamed to "script" later.
I'm using Aptana on Win 8 and came to the problem.
Now rails 4 doesn't have script/rails in the folder. We will need to create it manually in your application folder. You can simply create the folder, then mklink or copy the file in the script folder. Please take caution that your IDE will have proper access to the file you create, otherwise, you will come to the error:
c:\Ruby200\bin\rubyw.EXE: No such file or directory -- C:/Users/Zhou/Documents/GitHub/HR-SNA/script/rails (LoadError)
Go to project's root directory and execute from a console following command:
ln -s ./bin ./script
In Rails 4, script has been replaced with bin
I am receiving the error No such file or directory in my command line and I think it's because I am not saving the ruby files somewhere specific. All I did was create a random folder where I would save my ruby files.
Do I need to save my scripts in the original ruby folder? Thanks!
** This is Windows 7.
More info -
All I did was make a simple file named "Matz.rb" because I'm currently reading the O'reilly Ruby book. In my code all I wrote was puts "Hello Matz". I saved this on my desktop. When I go to the command line it and I write ruby matz.rb it says "ruby: No such file or directory -- matz.rb " Please help :(
If this has something to do with PATH or shells, I honestly have no idea what those really are because I just started coding last night.
You are most likely not in the right folder. You somehow need to tell the ruby interpreter where it is looking for the file.
Either make sure you're in the right folder - the cd command allows you to change location:
cd C:\Users\Username\Desktop
ruby Matz.rb
or specify the path explicitly:
ruby C:\Users\Username\Desktop\Matz.rb
By default, the ruby interpreter will look in your current directory (the location shown in your prompt) for whatever filename you give it.
Edit: I'll attempt to explain what I mean step-by-step.
When you initially open the command prompt, it will indicate what folder you are in (your "current working directory") in the prompt:
C:\Users\YourUsername >
In the above example, you are working in the C:\Users\YourUsername folder.
You can move directories using the cd command. For example, typing cd Desktop moves you into the folder called Desktop, assuming such a folder exists in your current location
You can move to another folder outside your current folder by specifying explicitly where you want to be: cd C:\Another\Place
When you run a ruby command such as ruby Matz.rb, the system knows how to find the ruby program because the installer placed its location into the PATH environment variable. Don't worry about this too much, this just explains the "magic" by which it knows what ruby means, no matter where you are.
Ruby finds the file you specify (in the above example, Matz.rb) by looking in the current directory. To re-iterate, it is looking in whatever folder is written right there in your prompt.
You can tell ruby to look outside the current folder by specifying the full path (as shown in the answer above).
To go from a new command window that you've just opened, to typing ruby Matz.rb and having it work, you need to do the following:
Move to the correct directory
Run the command
If we assume your username is alex and you have a folder on your desktop called "rubycode", which contains Matz.rb, you could do this:
Open a command prompt, which will most likely start in C:\Users\Alex
Move to the rubycode folder on your desktop: cd Desktop\rubycode. All subsequent commands will be working from within this folder.
Run the ruby command, specifying the file: ruby Matz.rb
Continue to run ruby commands as you learn ruby.
I hope that makes sense.
When I run rails new . hoping to create a new Rails app in my workspace directory, rails says:
Invalid application name 567101. Please give a name that does not start with numbers.
How do I get around this? I could just create it within the top level directory, but that seems inelegant. When you create a workspace and select "Rails" for the type it sets up the app nicely in the right place, but I want to set up a Rails 4 app, so that's not an option.
I was just trying to figure this out myself. What I ended up doing is creating a symbolic link to the numbered directory named rails_app. I was then able to do a rails new and have it create the application.
First
cd ~/
Then
ln -s ./567101 ./rails_app
Then
rails new ./rails_app
I'm a newbie and i'm working follow this link http://dima.github.com/2009/03/19/working-with-restfulx-model-attachments.html
But I stuck on the step run ./script/generate rx_config. I don't know how can I run it.
I tried to go to the path of folder script and typed generate rx_cofig on command line but it doesn't work.
C:\Data\Workspace\rx_model_attachments\script>generate rx_config
I got the error 'generate' is not recognized as an internal or external command, operable program or batch file.
Anyone can tell me step by step of doing this. Big thanks!
Since you're on windows, you will need to preface all of the scripts in the scripts folder with ruby:
C:\Data\Workspace\rx_model_attachments\script>ruby script/generate rx_config
The usual hash-bang (#!) at the start of the script files to let the shell know which interpreter to run does not work on windows.
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 :-)
