Windows cannot detect rails installation

[nitalchandel]

I installed Rails from http://railsinstaller.org/en on my Windows 7 desktop and the installation went fine. However, after installation when I do:

C:\Sites>rails --version
The system cannot find the path specified.

C:\Sites>ruby -v
ruby 2.2.4p230 (2015-12-16 revision 53155) [i386-mingw32]

C:\Sites>gem -v
2.4.5.1

C:\Sites>git --version
git version 1.9.4.msysgit.2

Not sure what I am missing here because the installation worked for me in the past.

Found the problem. It looks like the distributable (railsinstaller-3.2.0.exe which uses Ruby 2.2) provided on rails installer site (http://railsinstaller.org/en) is having some problem. When I picked the older version (railsinstaller-3.1.1.exe which uses Ruby 2.1) it was able to pick the rails version without any problem.

C:\>rails --version
Rails 4.2.5.1

C:\>ruby --version
ruby 2.1.8p440 (2015-12-16 revision 53160) [i386-mingw32]

Please note that the ruby version is downgraded from 2.2 to 2.1 here.

I experienced the same problem after installing (railsinstaller-3.2.0.exe which uses Ruby 2.2) and I found out that the content of rails.bat which resides in C:\RailsInstaller\Ruby2.2.0\bin has the wrong path.

@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/rails" %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" %*

So C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\Ruby2.2.0\bin\ruby.exe has to be C:\RailsInstaller\Ruby2.2.0\bin\ruby.exe.

Solved the exact same problem I had!

I had the same problem. Not to be captain obvious but I replaced:

"C:\Users\emachnic\GitRepos\railsinstaller-windows\stage"

With my install directory:

"C:\RailsInstaller"

For everything in the "C:\RailsInstaller\Ruby2.2.0\bin" folder, which was found in 26 places over 13 files.

OK!
So can someone please tell me where RailsInstaller got that path from?
Makes for a doubly frustrated noob too RubyonRails!

Same problem here on Win 10. Some bat files were correct other not. So resolution for me was:

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

With
:WinNT @"%~dp0ruby.exe" "%~dpn0" %*

After that rails -v started to show version

I just installed it today and the problem still persists, but thankful for this thread to point out the fix.

[williantenfen]

Still got same problem today.. Fixed it just like @DerJuggernawt did ....

[haagamble]

Could somebody please explain in more detail how to fix it. Thanks.

Try this steps:

gem sources -a http://rubygems.org//

gem install rails

[ashmaroli]

there are a bunch of old binaries distributed with this installer. so simply run the following:

gem update --system --no-document && gem update --no-document

The problem has not been fixed. Hiccups like this will eventually kill the Rails.

I copied this from jayantbh:

I opened all the files under C:\RailsInstaller\Ruby2.2.0\bin in Sublime Text, and replaced with Ctrl+Shift+F,
This
@"C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\Ruby2.2.0\bin\ruby.exe"
with this
@"%~dp0ruby.exe"
across all files that had a match.

This save your time also you must pay attention to the folder, in my specific case the version of ruby is 2.3.0, so you must the change the path for:
@"C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\**Ruby2.3.0**\bin\ruby.exe"

En español:

Abran Sublime y arrastren el folder bin de la instalación de rails (puede estar en C:\RailsInstaller\Ruby2.2.0\bin), luego presionan la combinación Ctrl+Shift+F para poder buscar y reemplazar en todos los archivos .bat al tiempo.
Find:
@"C:\Users\emachnic\GitRepos\railsinstaller-windows\stage\Ruby2.2.0\bin\ruby.exe"
Replace:
@"%~dp0ruby.exe"

Reemplazan, guardan y listo.
