rvm /usr/bin/env: ruby no such file error

Question

I've installed rvm + ruby systemwide.

which ruby
/usr/local/rvm/rubies/ruby-2.1.1/bin/ruby

and:

/usr/bin/env: ruby: No such file or directory

Everything else works fine, putting direct path of ruby in my executables work fine.

Solution 1

The PATH is what the env program uses to search for your executables. You can change this per-user (in the $HOME/.bashrc). In order to do that, run nano $HOME/.bashrc and go to the last line, add a new line

export PATH=$PATH:/usr/local/rvm/rubies/ruby-2.1.1/bin

To change it at a system level you sudo nano /etc/login.defs and change this line

ENV_PATH        PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

to

ENV_PATH        PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/local/rvm/rubies/ruby-2.1.1/bin

Solution 2

I recently faced this issue and took a different approach, so thought of sharing it. This happens when the ruby file is not present in the directory mentioned. So create a symbolic link to the ruby file in the directory and your error should be fixed.

cd /usr/bin/env

ln -s /usr/local/rvm/rubies/ruby-2.1.1/bin/ruby

Solution 3

I realize this is a somewhat old question, but I spent a day+ trying to nail this problem down, and I found what I think is a solid best practices type of solution -- use the rvm wrappers.

/usr/bin/env ruby gives you the capability to use the Ruby version of your choice so you don't have to edit the executable shell scripts (in /bin) with a hard coded directory path to make them work (I've seen this as a suggested fix elsewhere).

As noted in the answers above, the key is the $PATH setting in /etc/environment, but I came up with a different solution.

RVM gives us a symbolic link directory of all the installed ruby versions and aliases at /usr/local/rvm/wrappers/.

If you set your $PATH var to use the wrapper directory associated with the Ruby version you want to use e.g.

PATH="/usr/local/rvm/wrappers/ruby-1.9.3-p547:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

You will have set the RVM environment such that /usr/bin/env ruby_command will work.

At least this resolved this problem for me. I hope this helps someone out there save some time.

Have you added "/usr/local/rvm/rubies/ruby-2.1.1/bin" to the "PATH" in "/etc/login.defs"?

[Gunnar Hjalmarsson]

@SandroDzneladze: In Ubuntu the PATH variable is set in /etc/environment. That's where I would change it rather than in /etc/login.defs.

@GunnarHjalmarsson looks like a better place yes. But it doesn't fix the problem.

I tried the solution, somehow it is not working for ruby-2.2.2 and Ubuntu 14.04.2 LTS

What's the error? There are some install issues on Ubuntu with Ruby 2.2.+: ryanbigg.com/2014/10/ubuntu-ruby-ruby-install-chruby-and-you I'm still using v1.9.3 -- not looking forward to upgrading.

Hello Nihanth and than you for the answer! /usr/bin/env is not a directory on Ubuntu machines. Also your link command is missing a parameter.
