我该如何解决这个问题？

Answer 1

看来你有红宝石问题了。尝试使用以下方法安装2.6.3版本：

sudo gem install cocoapods -v 2.6.3

然后尝试运行sudo gem install cocoapods。如果此操作不起作用，请尝试以下操作：

开放终端并运行

curl -L https://get.rvm.io | bash -s stable

然后

rvm install ruby-2.6

这将为您安装红宝石，如果它还没有安装。在此之后，只需将ruby更新为新版本

rvm use ruby-2.6.3

将ruby 2.6.3作为默认设置

rvm --default use 2.6.3

希望你能跑

sudo gem install cocoapods
