任何人都知道发生了什么以及如何解决它？如何卸载所有内容并重新安装(无需卸载我的操作系统,真的很糟糕的人)

Answer 1

我试着通过运行来清理所有已安装的宝石

rm -rf ~/.gems
sudo rm -rf /Library/Ruby/Gems/*

在此之后gem list应列出没有宝石.然后跑

sudo gem update --system

确保Ruby Gems处于最新版本.然后,您将不得不重新安装所有宝石.(可能gem install bundler接着是bundle install).

顺便说一句,你应该检查rbenv或rvm来管理Ruby版本,并将所有开发宝石与系统Ruby分开.
