安裝cocoa pods時出現Operation not permitted
在更新完ruby，更換Ruby映象－－淘寶的那個映象(https://ruby.taobao.org/ )已經不可用了。官方的需要FQ。所以我們現在用最新支援的ruby映象(https://gems.ruby-china.org/)
安裝cocoa pods時，
在命令列中輸入：
安裝：sudo gem install cocoapods報Operation not permitted - /usr/bin/xcodeproj這個錯誤，解決辦法為：
用
sudo gem install -n /usr/local/bin cocoapods --pre
這段命令代替
sudo gem install cocoa pods
就完美解決了
安裝cocoapods的步驟為：
1、更新ruby
sudo gem update --system
2、
更換Ruby映象－－淘寶的那個映象(https://ruby.taobao.org/ )已經不可用了。官方的需要FQ。所以我們現在用最新支援的ruby映象(https://gems.ruby-china.org/)
需要的命令列：
gem sources --remove https://rubygems.org/
gem sources -a https://gems.ruby-china.org/
gem sources -l （用來檢查使用替換映象位置成功）
出現
*** CURRENT SOURCES ***
https://gems.ruby-china.org/
則說明成功了3、安裝cocoapods 命令列： sudo gem install -n /usr/local/bin cocoapods --pre
終端列印：
