Rails - The system cannot find the path specified

Question

I have installed Rails and Ruby on Windows with railsinstaller. The problem is, when I run the rails command, it gives me: \"The system cannot find the path specified.\"

Answer 1

Go into C:\RailsInstaller\Ruby2.2.0. In some of the .bat files, you'll find the following:

@ECHO OFF
IF NOT "%~f0" == "~f0" GOTO :WinNT
@"C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\Ruby2.2.0\bin\ruby.exe" "C:/Users/emachnic/GitRepos/railsinstaller-windows/stage/Ruby2.2.0/bin/tilt" %1 %2 %3 %4 %5 %6 %7 %8 %9
GOTO :EOF
:WinNT
@"C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\Ruby2.2.0\bin\ruby.exe" "%~dpn0" %*

Delete that and paste in the text below:

@ECHO OFF
IF NOT "%~f0" == "~f0" GOTO :WinNT
ECHO.This version of Ruby has not been built with support for Windows 95/98/Me.
GOTO :EOF
:WinNT
@"%~dp0ruby.exe" "%~dpn0" %*

I found your question while researching the same problem earlier, and I just fixed it for myself (Windows 8.1) so I thought I would answer it. I was trying to run Ruby 2.2 on Windows 8.1 using RailsInstaller. I am now able to run Ruby and Rails, albeit an older version. I think this is a problem with 64-bit architecture versus 32-bit, the latter of which seems to run fine. Here's how I did it:

1. First, read this blog post and see if this solves your problem, though I don't think it will. I used regedit.exe to find the AutoRun instance in question. I didn't have one, so I tried the next step.

2. Uninstall the Ruby 2.2 version of RailsInstaller (go into your control panel > programs and features then uninstall RailsInstaller.

3. Then, install the 1.9.3 version. Go here and CTRL+F "1.9" to find the Ruby 1.9.3 version of RailsInstaller.

4. Once installed, make sure to run a gem update --system to update all of your gems. I had trouble running rails new until I did the gem update. Now everything works fine.

So, you'll be using a slightly older version of Ruby but everything should be working okay. This solution worked for me and I hope it works for you.

I encountered the same issue and running gem install rails in the command prompt it works.

I've created a super easy way to do @JayantBhawal's solution (worked perfectly fine for me) with Windows Powershell, which you should all have since this seems like a problem exclusive to Windows machines. It looks complicated but really all it's doing is replacing all the instances of C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\Ruby2.2.0\bin\ruby.exe with %~dp0ruby.exe in the .bat files. Just open up Powershell, cd to C:\RailsInstaller\Ruby2.3.0\bin, and copy this small script:

Get-ChildItem . -Filter *.bat | Foreach-Object {
(Get-Content $_.name ) | ForEach-Object { 
    $_ -replace "C:\\Users\\emachnic\\GitRepos\\railsinstaller-windows\\stage\\Ruby2.2.0\\bin\\ruby.exe", "%~dp0ruby.exe" 
} | Set-Content $_.name}

After you hit enter, you should find that all the instances of that string have been replaced. GL

edit: updated version 2.2.0 -> 2.3.0

This is due to a bug in RailsInstaller, where two files have the location of ruby.exe hard-coded to work only on the RailsInstaller dev's machine. In C:\RailsInstaller\Ruby2.2.0\bin\rails.bat (this is the default install folder, you might have rails.bat somewhere else if you picked a different install folder) you'll find these two lines:

@"C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\Ruby2.2.0\bin\ruby.exe" "C:/Users/emachnic/GitRepos/railsinstaller-windows/stage/Ruby2.2.0/bin/rails" %1 %2 %3 %4 %5 %6 %7 %8 %9

@"C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\Ruby2.2.0\bin\ruby.exe" "%~dpn0" %*

The emachnic user is the RailsInstaller developer. As a workaround, you can change these folders to the ones on your computer. For the default install folder, you'd change these to:

@"C:\RailsInstaller\Ruby2.2.0\bin\ruby.exe" "C:\RailsInstaller\Ruby2.2.0\bin\rails" %1 %2 %3 %4 %5 %6 %7 %8 %9

@"C:\RailsInstaller\Ruby2.2.0\bin\ruby.exe" "%~dpn0" %*

You will have to repeat this change for two similar lines in C:\RailsInstaller\Ruby2.2.0\bin\bundle.bat as well.

Run rails -v to verify that rails is now working.

I solved this problem on my windows machine by doing

1. gem install bundler
2. bundler install
3. Number 1 and 2 fixed the problem and installed all gems.
