目錄權(quán)限不夠，解決方案
sudo chmod 777 /Library/Ruby/Gems/2.0.0
- 問題2：Permission denied - /Library/Ruby/Gems/2.0.0/cache/rubygems-update-2.6.4.gem
gem版本較低媳纬，更新gem
gem update --system
- 問題3：更新后還是不行双肤，執(zhí)行
sudo gem install cocoapods
- 問題4：Operation not permitted - /usr/bin/xcodeproj
解決方案，
sudo gem install -n /usr/local/bin cocoapods
- 問題5：pod install 時钮惠，提示[!] The dependency
