cocoaPods安装踩坑

执行：sudo gem install cocoapods

错误：Building native extensions. This could take a while...

ERROR:  Error installing cocoapods:

ERROR: Failed to build gem native extension.

执行：xcode-select--install

xcode-select -p

rvm -v

错误：no such file or directory

执行：curl -L https://get.rvm.io | bash -s stable 进行安装

安装完成：Thanks for installing RVM 🙏

Please consider donating to our open collective to help us maintain RVM.

切换到RVM环境：source ~/.rvm/scripts/rvm

查看版本：rvm -v

rvm （1.29.12 版本号） (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

在rvm环境中查询已经安装的ruby

rvm list

# No rvm rubies installed yet. Try 'rvm help install'.

发现rvm路径下里并没有ruby环境

查看所有ruby版本：

rvm list known

执行：

rvm install 3.0.0（要安装的版本号)

不添加版本号会报错：Can not use or install 'all' rubies. You can get a list of installable rubies with 'rvm list known'.

安装完成：

Install of ruby-3.0.0 - #complete 

Ruby was built without documentation, to build it run: rvm docs generate-ri

查看是否安装成功：

rvm list

安装成功：

# => - current

# =* - current && default

#  * - default

执行：sudo gem install cocoapods
