問題(issues)
使用sudo gem install cocoapods更新当犯！報錯如下：
Building native extensions. This could take a while...
ERROR: Error installing cocoapods:
ERROR: Failed to build gem native extension.

嘗試了gem update --system徐勃、xcode-select --install、sudo apt-get install ruby-dev等方法都未解決該問題迟赃！
最終解決方法
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
根據(jù)提示安裝即可
