非常坚持cocoapods / ruby​​设置

Question

这工作正常然后突然间没有。我希望我知道为什么。真的卡住了，在网上找不到任何东西。我正在研究一个ObjectiveC项目。我尝试用以下方法重置所有内容：

$ sudo gem uninstall ruby
$ sudo gem uninstall cocoapods

然后

$ sudo gem install ruby
$ sudo gem install cocoapods
$ sudo gem update ruby
$ sudo gem update cocoapods

然后我在我的项目目录中运行

$pod install 

并收到以下错误。我在所有项目上得到了这个。

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:110:in `require': cannot load such file -- cocoapods-core (LoadError)

非常感谢任何想法/线索/答案。

我通过运行

重新安装了可可豆荚

$ sudo gem uninstall cocoapods-core cocoapods-downloader cocoapods
$ sudo gem install cocoapods

这解决了我的问题

您似乎错过了CocoaPod的依赖项之一。您应该可以使用以下命令安装它：

[sudo] gem install cocoapods-core
