错误 sudo:gem:找不到命令 [英] Error sudo: gem: command not found

问题描述

我正在尝试在 CentOS 上安装 ruby​​rep，但在执行 sudo gem install ruby​​rep 时出现错误 sudo: gem: command not found.Sudo 和 gem 都已安装并可以正常工作，只是组合时没有.

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.

我的设置:

[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

推荐答案

尝试不使用 sudo.如果你做了 ruby​​ 的 root 安装，你应该只使用 sudo，这是不推荐的.

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