CooaPods的终端安装

如何解决CooaPods的终端安装

这是我的终端导出：

这里是 pod init：

Masons-iMac:GoodDays nacly$ ls
GoodDays        GoodDaysTests
GoodDays.xcodeproj  GoodDaysUITests

Masons-iMac:GoodDays nacly$ pod init
-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory

这里是 cocoapods 的安装：

Masons-iMac:GoodDays nacly$ sudo gem install cocoapods
Password:
Building native extensions. This Could take a while...

ERROR:  Error installing cocoapods:
    ERROR: Failed to build gem native extension.

    current directory: /Library/Ruby/Gems/2.6.0/gems/ffi-1.14.2/ext/ffi_c
/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 ./siteconf20210114-6600-1nfobc.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-1.14.2 for inspection.

最后一点。我尝试更新 RubyGems：

Masons-iMac:GoodDays nacly$ gem update --system
Updating rubygems-update
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.6.0 directory.

我也试过这个：
