关于ERROR: While executing gem ... (Errno::EPERM)Operation not permitted - /usr/bin/xcodeproj的问题

今天安装cocoods 出现下面的问题：ERROR: While executing gem ... (Errno::EPERM) Operation not permitted - /usr/bin/xcodeproject

第一种方法（我是用此方法解决的）：终端输入

mkdir -p $HOME/Software/ruby

 export GEM_HOME=$HOME/Software/ruby

 gem install cocoapods

export PATH=$PATH:$HOME/Sofware/ruby/bin

 pod --version

一行一行的输入

第二种解决办法如下：

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

就完美的解决了，代替原来的：

sudo gem install cocoapods

附录：安装步骤

1、打开mac的命令窗口

输入：

gem sources --remove https://rubygems.org/ gem sources -a https://ruby.taobao.org/ gem sources -l

2、安装cocopods

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

或者一起输入到终端

mkdir -p $HOME/Software/ruby

export GEM_HOME=$HOME/Software/ruby

gem install cocoapods

export PATH=$PATH:$HOME/Sofware/ruby/bin

pod --version
