安装Cocoapods 0.35.0时出错

Question

我正在尝试使用以下命令安装Cocoapods版本0.35.0：

sudo gem install cocoapods --version 0.35.0

当我尝试验证版本时

pod --version

我收到以下错误：

0.35.0

我试图卸载cocoapods和xcodeproj并重新安装它，但它不起作用。 之前我还有其他三个类似的错误，但我已经摆脱了它们

sudo gem update --system

不过，我无法修复最后一个错误。

Answer 1

有同样的问题。 Cocoapods改变了对cocoapods_plugin.rb的读取权限。 尝试：

sudo chmod 644 /Library/Ruby/Gems/2.0.0/gems/cocoapods-stats-0.6.0/lib/cocoapods_plugin.rb

Answer 2

我通过使用RVM解决了这个问题，因为我发现错误可能与我的mac上的ruby版本控制有关。 我刚安装它

\curl -sSL https://get.rvm.io | bash -s stable --ruby

然后Cocoapods安装顺利。

Answer 3

我遇到了与ruby 2.1.2相同的问题，但似乎。 ruby-2.2.2工作正常
