不出意外的话，马上就要出意外了。

前言

自己开发过程中就习惯记录下来的疑问点和可优化的点，然后在空闲的时候就挨个处理它们，这不，还没开始就遇到问题了。

正文

操作很简单，就新建一个demo，然后在执行pod init的时候，出现了以下报错，

### Error

气不打一处来，版本重复，解决方案也很粗暴

sudo gem uninstall cocoapods

输入密码后

Successfully uninstalled cocoapods-1.9.3
Successfully uninstalled cocoapods-1.10.0
Remove executables:
    pod, sandbox-pod

in addition to the gem? [Yn]  y
Removing pod
Removing sandbox-pod
Successfully uninstalled cocoapods-1.10.1

再次安装

sudo gem install cocoapods

整完再pod init，完美。

如果有这种提醒的

Ignoring eventmachine-1.2.7 because its extensions are not built. Try: gem pristine eventmachine --version 1.2.7

直接

sudo gem pristine eventmachine --version 1.2.7

后记

要去解决问题，木得后记。
