    from /usr/local/rvm/rubies/ruby-2.2.2/bin/gem:21:in `<main>'

谁能帮我解决这个错误。我正在尝试将它安装在远程服务器上，并因这个错误而大吃一惊。我已成功安装 ruby，但 rails 出现问题。

Answer 1

首先，检查您的 rvm，如果找不到请尝试使用：

echo "source $HOME/.rvm/scripts/rvm" >> ~/.bash_profile

或

echo "source $HOME/.rvm/scripts/rvm" >> ~/.bashrc

加载 RVM。

终于可以使用@MattW的推荐安装了
