在更新完ruby，更換Ruby鏡像－－淘寶的那個鏡像(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持的ruby鏡像(https://gems.ruby-china.org/)

安裝cocoa pods時，

? 在命令行中輸入：

? 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鏡像－－淘寶的那個鏡像(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持的ruby鏡像(https://gems.ruby-china.org/)

? 需要的命令行：

??gem sources --remove https://rubygems.org/?
? gem sources -a https://gems.ruby-china.org/?
? gem sources -l ?（用來檢查使用替換鏡像位置成功）

? 出現

*** CURRENT SOURCES ***

https://gems.ruby-china.org/

則說明成功了

3、安裝cocoapods ?命令行：?sudo?gem?install?-n?/usr/local/bin?cocoapods?--pre

終端打印：

MacintoshdeiMac:~ Mac$ sudo gem install -n /usr/local/bin cocoapods --pre ?
