我正尝试按照“How to Install Ruby on Rails on Ubuntu 12.04 LTS (Precise Pangolin) with RVM”中的步骤在 Ubuntu 上安装 Ruby on Rails。
一切都很好，直到这里:
gabi@ubuntu:~$ rvm rubygems current Removing old Rubygems files... Installing rubygems-1.8.25 for ruby-1.9.3-p385 ... Error running 'env GEM_PATH=/home/gabi/.rvm/gems/ruby-1.9.3-p385:/home/gabi/.rvm/gems/ruby-1.9.3-p385@global:/home/gabi/.rvm/gems/ruby-1.9.3-p385:/home/gabi/.rvm/gems/ruby-1.9.3-p385@global GEM_HOME=/home/gabi/.rvm/gems/ruby-1.9.3-p385 /home/gabi/.rvm/rubies/ruby-1.9.3-p385/bin/ruby /home/gabi/.rvm/src/rubygems-1.8.25/setup.rb', please read /home/gabi/.rvm/log/ruby-1.9.3-p385/rubygems.install.log Installation of rubygems did not complete successfully.
The log file looks like this:

到底是什么问题，我该如何解决？
最佳答案
不确定是什么问题，我认为安装时出了点问题，但是我设法通过使用 here 中的快速修复使其正常工作:
- 更新 RVM 使用:
rvm get head - 使用以下命令删除所有手动安装的包:
rvm pkg remove - 使用以下命令安装所需的库:
rvm requirements run - 使用以下方法重新安装 Ruby:
rvm reinstall 1.9.3
