安裝CocoaPods時提示無權(quán)限錯誤：

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

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.
stevenwang@StevendeMacBook-Pro ~ % ruby -v

解決辦法：

1.刪除CocoaPods;

2.用命令"which -a ruby"，查看只有一個系統(tǒng)自帶的ruby目錄严里。

StevendeMacBook-Pro:~ root# which -a ruby
/usr/bin/ruby

需要自己再安裝一個最新版本的ruby:


stevenwang@StevendeMacBook-Pro ~ % brew install ruby

==> Caveats
By default, binaries installed by gem will be placed into:
  /usr/local/lib/ruby/gems/3.1.0/bin

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have ruby first in your PATH, run:
  echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

For compilers to find ruby you may need to set:
  export LDFLAGS="-L/usr/local/opt/ruby/lib"
  export CPPFLAGS="-I/usr/local/opt/ruby/include"

安裝完后檢查漓柑，發(fā)現(xiàn)還是只有一個系統(tǒng)目錄：

stevenwang@StevendeMacBook-Pro ~ % which -a ruby
/usr/bin/ruby
stevenwang@StevendeMacBook-Pro ~ %

這時需要把新版本加到環(huán)境變量中：

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc
stevenwang@StevendeMacBook-Pro ~ % source ~/.zshrc
stevenwang@StevendeMacBook-Pro ~ % 
stevenwang@StevendeMacBook-Pro ~ % which -a ruby  
/usr/local/opt/ruby/bin/ruby
