当我尝试运行 rails db:migrate 时，我已经提取了我工作中的一个项目。 ，终端要求安装“Bundler 2”所以我这样做了。

现在，当我尝试做 rails db:migrate我有以下错误:

gem uninstall rubygems-bundler

为我工作
我正在使用捆绑器 2.1.0

REF: https://github.com/bundler/bundler/issues/7492

显示时

ERROR:  While executing gem ... (Gem::InstallError)
    rubygems-bundler is not installed in GEM_HOME, try:
    gem uninstall -i /Users/xxxx/.rvm/rubies/ruby-2.5.7/lib/ruby/gems/2.5.0 rubygems-bundler

请运行

gem uninstall -i /Users/xxxx/.rvm/rubies/ruby-2.5.7/lib/ruby/gems/2.5.0 rubygems-bundler
