pod init报错

今天想熟悉一下ReactiveCocoa框架.
然后是千篇一律的操作,来新建一个空项目,深思熟虑的起名之后一顿Next,就创建好了.
接下来是略有逼格的命令操作,cd到当前项目目录下,初始化一个pod文件,一个华丽的pod init加回车,尽显逼王风采.

擦??~~~,报错,啥情况??

出事了快找搜索引擎,输入pod init Search for existing GitHub issues similar to yours:

然后找到了答案,让我卸载pod 重新安装

sudo gem uninstall cocoapods

输入密码之后发现列出了两个cocoapods版本

Select gem to uninstall:
 1. cocoapods-1.2.1
 2. cocoapods-1.3.1
 3. All versions

果断按3
输出如下(确认按Y):

Successfully uninstalled cocoapods-1.2.1
Remove executables:
    pod, sandbox-pod

in addition to the gem? [Yn]  y
Removing pod
Removing sandbox-pod
Successfully uninstalled cocoapods-1.3.1

重新安装cocoapods

sudo gem install cocoapods

一顿疯狂的输出之后是前所未有的畅快

接下来pod init

成功~~~!!
