I have installed RVM along with ruby versions. However if I fire up the console and run the command rails server, bundle install, etc. I get this error
bash: /us
I just solved the same problem on Windows Vista.
My console was giving me this message:
$ rails -v
sh: /c/RailsInstaller/Ruby1.9.2/bin/rails: C:/Projects/railsinstaller/Stage/Ruby1.9.2 /bin/ruby.exe: bad interpreter: No such file or directory
I just edited the first line of this file:
C:\RailsInstaller\Ruby1.9.2\bin\rails
And made it point to the correct location for ruby.exe, on my system, like this:
#!C:\RailsInstaller\Ruby1.9.2\bin\ruby.exe
Et voilà, problem solved!
