This may be related to what i did here.. but when I type the command

which rails

I get


but when i type

rails --version

I get:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/universal-darwin13/rbconfig.rb:212: warning: Insecure world writable dir /Development/android-sdk-macosx in PATH, mode 040777
Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

You can then rerun your "rails" command.

how does that make sense?

Command which rails runs program which that just searches for a executable file called rails on PATH variable entries (see echo $PATH or env | grep PATH). Executable rails is not run at all in this case.

Command rails --version executes the executable file /usr/bin/rails and it fails because of missing libraries.

    hum.. so it seems the meaning of this is that I did install rails before, but then i deleted some of its libraries.. so now i got just a shell of it's former self (sorry for the dramatic wording).. and so i gotta reinstall eh

  • @abbood Yes, it seems to be the case. Install missing libraries or the whole thing at once. Dec 6, 2013 at 8:38
