记录cocoapods 的一次报错
作者：互联网
使用pod init 出现bad interpreter: No such file or directory
导致这个问题出现的原因，升级了macOS系统造成的cocoapods不能正常使用
So，就跟着更新一遍就好了，然而...
$ sudo gem update --system
$ sudo gem install cocoapods -n/usr/local/bin
当执行 $ sudo gem install cocoapods -n/usr/local/bin， 报错了
You might have to install separate package for the ruby development environm
具体更多的输出信息：
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/bin/ruby -I /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0 -r ./siteconf20200430-75028-3e0jka.rb extconf.rb
mkmf.rb can’t find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/include/ruby.h
You might have to install separate package for the ruby development
environment, ruby-dev or ruby-devel for example.
extconf failed, exit code 1
Gem files will remain installed in /Library/Ruby/Gems/2.6.0/gems/ffi-1.12.2 for inspection.

好，这时从网上看到的解决方法
输入 xcode-select --install
然而，提示 “不能安装该软件因为当前无法从软件更新服务器获得“
解决办法：
1）升级xcode到最新版本，然后执行xcode-select –install
2）或者去developer apple网站上手工下载对应版本的 Command Line Tools
好，以为这样可以了，执行pod init
报错：

此时执行 sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
完成，究其原因，因为此Xcode是通过developer 下载，原来的又是拖动删除，导致路径错误。
