非常坚持 cocoapods / ruby​​ 设置

Question

这工作正常，然后突然就不行了。我希望我知道为什么。真的卡住了，在网上找不到任何东西。我正在做一个ObjectiveC项目。我尝试使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 

并得到以下错误。我在所有项目中都得到了这个。

/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)

任何想法/线索/答案将不胜感激。

Answer 1

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

这为我解决了问题

Answer 2

看起来您缺少 CocoaPod 的依赖项之一。您应该能够安装它：

[sudo] gem install cocoapods-core

Answer 3

您应该停止在“gem install”等任务中使用“sudo”。这里有一个关于如何修复 ruby​​ 的小教程，以确保您不会看到 cocoapods（和其他 gem）的权限问题：
