Question

任何时候我运行$ gem update或尝试使用$ gem install ....我收到此错误：

ERROR:  While executing gem ... (TypeError)
no implicit conversion of nil into String

昨天一切正常，我不确定发生了什么。我已经运行了$ bundle install，$ bundle update，$ gem update。

如果有人能指出我正确的方向让轨道和宝石再次工作，我将非常感谢你。

我无法宝石安装机架-v 2.0.1，也没有宝石更新机架，同时出现上述错误。

Gemfile：

    source 'https://rubygems.org'
