安装cocoapods问题汇总

sudo gem install cocoapods
           

安装后，发现输完密码一直没动静。问题是因为“https://rubygems.org/“被墙了，更换gem源为“https://gems.ruby-china.org/“即可：

gem sources --add https://gems.ruby-china.org/ --remove https://rubygems.org/
           

再次执行“sudo gem install cocoapods“仍然报错：

ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: cocoapods requires cocoapods-core (= ), cocoapods-downloader (< , >= ), cocoapods-trunk (< , >= ), molinillo (~> ), xcodeproj (< , >= ), colored (~> ), escape (~> ), fourflusher (~> ), gh_inspector (~> ), nap (~> ), ruby-macho (~> ); activesupport requires i18n (>= , ~> ), tzinfo (~> ), minitest (~> ), thread_safe (~> ); cocoapods-plugins requires nap (>= )
           

出现这个问题是因为ruby版本太低，执行：

接着报错：

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

报这个错是因为权限不够，加上sudo：

sudo gem update --system
           

接着就开始babala，开始安装了：

Updating rubygems-update
……
……
……
ERROR:  While executing gem ... (Errno::EPERM)
    Operation not permitted - /usr/bin/xcodeproj
           

撞到最后又丫的报错啦。网上搜索了一下，解决方案是：

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

坑有点多，也不怕吓坏小朋友，真是的……
