brew upgrade引发的ssl小问题

brew upgrade

今天手哆嗦了一下，brew upgrade打出去了，然后开始自动更新所有的包……

过了一会需要写代码了，打开pycharm
Referenced from: ~/.pyenv/versions/3.6.9/lib/python3.6/lib-dynload/_ssl.cpython-36m-darwin.so

以为缺少了ssl模块，就pip install ssl

Collecting ssl

自己是Mac，想了想，之前没啥事怎么突然电脑就出问题了呢，好像brew操作了？！

这期间各种谷歌、百度、搜索

好像ssl都跟openssl相关，就搜索brew --prefix openssl

嗯啥时候多了个版本的

好吧，都是我的错不该更新所有的软件(关键是我不知道呀)

因为python是编译安装的，是基于上一次编译的系统环境编译的，那么这次我的python出问题就是因为系统环境出了点问题，所以我选择重新编译python
之前还测试了好几遍……

解决办法：

• 自己是用pyenv管理多个python环境，所以根据之前配置好的pyenv直接
  删除(记得备份自己常用的模块包pip freeze > requirements.txt)
• 然后pyenv uninstall 3.6.9
  这个时候你基于3.6.9的环境会提示要不要删除，
  
  pyenv uninstall.png
  
  我无所谓就删除了，谁测试下不删有没有影响呢
• 然后重新安装pyenv install 3.6.9

果然，用的是我brew upgrade之后的系统环境

后记

记得以后不要随随便便就更新所有的软件(抽它抽它-手:招你惹你了……)，影响其他软件的软件最好锁定了
brew pin [email protected]
需要更新的时候主动放开unpin

• 以后在更新之前，用 brew outdated 查看哪些包可以更新
  brew outdated
• 最好指定你想要更新的某个软件
  brew upgrade 指定包名
• 当然了还有更新所有的包
  brew upgrade # 猥琐发育，别浪啦

python2已经不更新了，除了系统自带python2，自己安装都是python3
