问题一、 zsh: /usr/local/bin/pod: bad interpreter: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: no such file or directory

显示找不到ruby，是shell地址改变了 变成了zsh。好嘛，重装一下。

1、重装一下 ruby：brew install ruby 

Error: The following directories are not writable by your user:/usr/local/sbin

You should change the ownership of these directories to your user.

          sudo chown -R $(whoami) /usr/local/sbin

And make sure that your user has write permission.

          chmod u+w /usr/local/sbin

执行：sudo chown -R $(whoami) /usr/local/sbin

            chmod u+w /usr/local/sbin

2、检查ruby brew doctor

问题：Warning: Homebrew's sbin was not found in your PATH but you have installed

formulae that put executables in /usr/local/sbin.

Consider setting the PATH for example like so:

              echo 'export PATH="/usr/local/sbin:$PATH"' >> ~/.zshrc

Warning: Broken symlinks were found. Remove them with `brew cleanup`: /usr/local/bin/code

执行 echo export PATH="/usr/local/sbin:$PATH"

执行 brew cleanup

3、 下载cocoapods：sudo gem install cocoapods

报错：ERROR:  Could not find a valid gem 'cocoapods' (>= 0), here is why:

          Unable to download data from https://ruby.taobao.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (certificate rejected) (https://ruby.taobao.org/specs.4.8.gz)

因为之前是淘宝ruby,不维护了。

添加ruby-china：gem source -a https://gems.ruby-china.com

删除：gem sources --remove https://ruby.taobao.org/

查看详情：gem sources -l

4、下载：sudo gem install cocoapods

pod运行： pod setup

5、到指定路径 执行pod install

错误1：curl: (7) Failed to connect to 127.0.0.1 port 1080: Connection refused

错误2：curl: (7) Unable to receive initial SOCKS5 response.

我是因为添加了代理：export ALL_PROXY=socks5://127.0.0.1:1080

取消代理：unset ALL_PROXY

可以执行命令查看代理 env|grep -I proxy

如果没有 去vi ~/.zsh_profil 查看或者其他你写入得地址。

如果写在了~/.zsh_profil，执行命令：vi ~/.zsh_profil，删除代理

再执行命令生效： source ~/.zsh_profil

6、pod install 完成
