So I installed Ruby On Rails using the Windows Installer.
Now the startup guides says I have to start up an Terminal and run the Rails command to make a project. I don't have a terminal, so how do I execute a Rails command and make a project??
The CMD command line in Windows does not recognize "rails"
I don't think it is an PATH problem, because when I'm in the "Bin" directory, there is "rails.bat" and "rails" with no extension. If I run Rails.bat I get "The filename, directory name, or volume label syntax is incorrect."
I get that message with whatever Argument I pass to it.
It seems to be a bug in the rails.bat file because of double-quotes, like:
#"ruby.exe"" "%~dpn0" %*
Remove the double quotes:

To get a terminal
Start > Run... or Windows key + R
Type "cmd" and hit enter.
To add a folder to the command line's path
On Windows XP (Vista is similar)
Start > Control Panel > System
Click the "Advanced" tab
Click "Environmental Variables"
Under "System Variables" double click on Path and edit accordingly.
You will need to open a new command line in order to get the updated path to take affect. With XP, I've had to reboot to force it to take affect but it shouldn't be necessary.
The Path variable is a semi-colon seperated list of folders in which the Command Line or "terminal" looks for commands.
You'll probably have to find the rails command yourself. I would try looking for a rails.bat or rails.cmd file.
I think they mean the command window. Try running it from a command line.
I dont know where the Windows Ruby on Rails intaller places its files, but the ultimately solution is that you need to make sure that the "rails" command is is your PATH - which you can view/modify by right-clicking My Computer, selecting Properties, going to the Advanced tab and then clicking on "Environment Variables" and then scrolling down until you see "PATH" and adjusting it accordingly. You probably need to find the directory where the "rails" command lives and append to the end of the existing PATH entry, inserting a ";" before you enter the new path to append it to the existing PATH.
So find where "rails" is and add its directory to your PATH.
You probably have to change your PATH in Windows to point to wherever the rails executable has been installed.
The PATH environment variable is used to determine where Windows looks for stuff; when you type, for instance, 'calc' Windows will hunt through its PATH and eventually find and run C:\Windows\calc.exe. In your case, the PATH doesn't include the directory you need, so Windows isn't searching in that directory for rails.exe when you type "rails."
To fix this, right click on "My Computer" -> "Properties" -> "Advanced" -> "Environment Variables" and then modify the PATH one to include the directory your rails.exe is in.
I recommend using cygwin for Rails development on windows - far too much of the community is using *nix. If you install the development tools package you'll automatically have svn, git and other doo-dads that you'll eventually need relating to various rails plugin installation. If you want to deploy using capistrano the installation is identical to all the instructions you find. Plus other tips and tricks people will reference will work exactly the same for you as it does for them, whereas some things are different for native windows and all the accessory tools have to be installed separately.

I am trying to run the following command on my Rails app on my Windows 10 machine:
rails credentials:edit
But I get the following error message:
No $EDITOR to open file in. Assign one like this:
EDITOR="mate --wait" bin/rails credentials:edit
For editors that fork and exit immediately, it's important to pass a
wait flag, otherwise the credentials will be saved immediately with no
chance to edit.
I did some research, and I understand that most people who want to run such aforementioned command on Windows 10 will need to install a Linux Subsystem on their Windows machines. However, such option is not available for me because I don't have admin rights on my machine. I have attempted installing a Linux subsystem by using resources like the one here without luck.
I'm using VS Code and Powershell within VS Code, and this works for me:
> $env:EDITOR="code --wait"
> rails credentials:edit

I didn't find any of the answers above worked for me. Notepad complained about the directory being incorrect and gave me a blank file.
I got it to work with Notepad++ by doing the following:
SET EDITOR="C:\Program Files\Notepad++\notepad++.exe"
rails credentials:edit
I didn't need to use the --wait flag.
I would suggest you switch to non-windows based system if you're trying to do any rails development as I used to work on a windows machine until I caved in and switched entirely to Mate Linux. It would be so much easier to develop Rails application on Linux platform since you would see almost all gems compiling without any issue and all the rails terminal commands are working without further setup.
However, if you would like to edit your credentials, you need a text editor (Usually vim on Linux) setup before running credentials:edit.
First run SET EDITOR="notepad_path" and then try running rails credentials:edit
You can change notepad_path to any other text editor you prefer. However, some editors like Atom was giving weird issues for me.
find your pathing to your local text editor (for windows its Notepad) you can search notepad and right-click and open the file location
right-click notepad and open properties then copy the Target:(EX.( "%windir%\system32\notepad.exe"))
now paste the target in SET EDITOR="target_path"
EX. SET EDITOR="%windir%\system32\notepad.exe"
now you can run bundle exec rails credentials:edit and notepad should come up with the decrypted info
If you are in a Windows environment, I highly recommend to use the classic notepad. In my experience using Notepad++, sometimes it opened correctly but didn't save, instead it works perfect with the classic notepad.
Also to run those mentioned commands, better use the classic cmd shell console, it might not work properly in PS (Power Shell) console. Good luck!
No $EDITOR to open file in. Assign one like this:
EDITOR="mate --wait" bin/rails credentials:edit
For editors that fork and exit immediately, it's important to pass a wait flag,
otherwise the credentials will be saved immediately with no chance to edit.
solution:
$env:EDITOR="notepad"
rails credentials:edit
I'm using windows 10 and here are the steps that I took:
make sure you have the path of your text editor in environment variables PATH
to do that, copy the file location of your text editor
right click on my computer(This PC) > select properties > advanced system settings > environment variables
on System variable box, click for "Path" > click edit > new > paste text editor file location
restart command line then try to open text editor using the command line. I'm using sublime and entering "subl" will open sublime text editor
cd to your project folder then run the following command:
set EDITOR=subl --wait
where subl is the executable file of the text editor
also without double or single quote, this will work since subl is an executable file and was registered on environment variable (if using notepad use: notepad).
Without the --wait flag, your credentials.yml.enc will be saved immediately without giving you the chance to edit.
alternatively you can directly set EDITOR similar to this:
set EDITOR="C:\filepath\to\your\editor --wait"
this time with quotes
Finally run:
rails credentials:edit
[Windows 8.1]
I'm using SET EDITOR="C:\Program Files (x86)\Notepad++\notepad++.exe" -multiInst -notabbar -nosession -noPlugin command to set the editor and it works.
Next, just run rails credentials:edit command. Then you can edit the credentials.yml file. Save it and close the Notepad++ windows. Then the credentials is encrypted and saved automatically.
Got it working (using PowerShell) with
$env:EDITOR="notepad"
then
bundle exec rails credentials:edit
Minutes ago, I downloaded the oscurrency code from github, and I'm installing oscurrency on heroku. Everything seemed to be going perfectly until this command:
rake heroku:install
on the command line, in the directory where I downloaded the source code. I get the error:
'rake' is not recognized as an internal or external command, operable program or batch file.
I'm following the installation instructions at heroku here:
https://github.com/oscurrency/oscurrency/wiki/Heroku-Deployment-Guide
The command "rake heroku:install" is in the third paragraph from the bottom.
The code I downloaded came in a top-level folder called oscurrency. I downloaded that onto my laptop in C:\me\oscurrency. I was issuing the command in that directory when I got the error. I tried issuing the command in the folder C:\me\oscurrency\oscurrency -- same error.
Maybe the command has changed for some reason. Anybody have an idea what's going wrong?
Your problem is most likely that the command prompt is looking for a file named rake.exe and not able to find it because your PATH environment variable is not set to include that directory. I suspect that the rails command won't work either. You should add the ruby install directory (probably C:\Program Files\Ruby on Rails\bin\ to your PATH environment variable.
To do this, open your Computer Properties by right-clicking My Computer and selecting Properties, then find the "Advanced System Settings" link. Click the "Environment Variables" button at the bottom, and paste the path to that directory into the PATH variable, separating it with a semicolon.
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.
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 installed Ruby and Ruby on Rails yesterday on Vista 32bit using the directions on this site: http://rubyonrails.org/down
So I downloaded the installer, then Gems, then I downloaded rails with Gems.
Now I can't use the Gem or Ruby commands in the command line... so I assume there's something wrong with the environment variables, but I hav eno idea how to set them up in Vista or what to put.
Can anyone help me with this?
To set up the environment variables, do this
Fire up the start menu
Right-Click on Computer and select Properties
Click Advanced system settings in the left-hand bar, and confirm the UAC prompt
Select the Advanced tab (it's 3rd)
Click Environment Variables... (at the bottom)
In the top box (User variables for XXX) either find the entry for PATH, or click new to create the entry.
If there is already a PATH use semi-colons to seperate each directory listed in it
Put c:\ruby\bin (change if you installed ruby somewhere else) in.
Click OK a lot of times to close all the windows we opened.
Restart your command prompt.
gem and ruby and irb should now all work. Whoever said that GUI tools are slower than command line tools. pshaw!
In the command line window type PATH then hit return, do you see ruby.exe on the PATH environment variable?
If you installed ruby to say c:\ruby then it'll be c:\ruby\bin\.
Looks like it may be missing from the path.
Add your ruby bin directory to your PATH environment variable, go to Control Panel -> System -> Advanced system settings, then go to the Advanced tab, Environment Variables, then edit your PATH variable and append the path to the ruby binaries install i.e. ;C:\ruby\bin
