什么时候安装cocoapods得到错误？

Question

我尝试和gem安装cocoapods我收到一个错误：

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

这是什么意思???

Answer 1

您需要成为root用户才能写入/Library，因此您需要使用sudo，因为the instructions告诉您：

$ sudo gem install cocoapods
