Error sudo: gem: command not found

I'm trying to install rubyrep on CentOS, and when executing sudo gem install rubyrep I get the error sudo: gem: command not found. Sudo and gem are both installed and working, just not when combined.

My setting:

[rubyrep]# which sudo
/usr/bin/sudo
[rubyrep]# which gem
/usr/local/rvm/rubies/ruby-2.1.2/bin/gem
[rubyrep]# which ruby
/usr/local/rvm/rubies/ruby-2.1.2/bin/ruby
[rubyrep]# $PATH
-bash: /usr/local/rvm/gems/ruby-2.1.2/bin:/usr/local/rvm/gems/ruby-2.1.2@global/bin:/usr/local/rvm/rubies/ruby-2.1.2/bin:/usr/local/rvm/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin: No such file or directory
Solution

  • Try without sudo. You should only use sudo if you did a root installation of ruby, which is not recommended.
