在安装cocoapods时遇到了问题

MBP-2 ~ % sudo gem install cocoapods                 

Password:

ERROR:  While executing gem ... (Gem::FilePermissionError)

    You don't have write permissions for the /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/gems/2.6.0 directory.

说是没有权限，然后又找了个命令

MBP-2 ~ % gem install cocoapods --user-install

WARNING:  You don't have /Users/flyyang/.gem/ruby/2.6.0/bin in your PATH,

  gem executables will not run.

ERROR:  While executing gem ... (Gem::FilePermissionError)

    You don't have write permissions for the /Users/flyyang/.gem/ruby/2.6.0 directory.

又报错，缺环境变量，那就把环境变量加上

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

source ~/.zshrc

继续执行命令

gem install cocoapods --user-install

输出：

Fetching nanaimo-0.3.0.gem

Fetching colored2-3.1.2.gem

。。。

Fetching activesupport-7.1.3.2.gem

WARNING:  You don't have /Users/flyyang/.gem/ruby/3.3.0/bin in your PATH,

  gem executables will not run.

ERROR:  While executing gem ... (Gem::FilePermissionError)

    You don't have write permissions for the /Users/flyyang/.gem/ruby/3.3.0 directory.

坏了，还报错。还是没权限缺环境变量

接下来执行这句

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

输出：

。。。
34 gems installed

成了，现在就可以pod install
