swift - Xcode：Pod update ArgumentError - Pod::Version 与 Gem::Version 的比较失败

Question

Pod install 工作找到，但 pod update 得到错误：

ArgumentError - comparison of Pod::Version with Gem::Version failed

之后我运行这个命令：

sudo gem update

但我得到这个错误：

You don't have write permissions for the /usr/bin directory.

搜索后，我运行以下命令：

sudo gem install cocoapods -n /usr/local/bin

我收到此错误：

undefined method `source_paths' for #<Gem::Specification:0x3fda7748b868 cocoapods-1.10.1>
