python3使用pip安装pyautogui过程中遇到的几个问题
最近想要做一个模拟鼠标点击的小程序（具体原因不说了哈：）），就想到使用python，上网搜了一下，很多都使用pyautogui这个库的，于是就想要安装pyautogui，但是过程中遇到了几个坑，写此博记录一下，当然也很高兴可以为看到此博的你解决同样的问题。
先写一下自己的环境：操作系统windows7 64位，python版本python-3.7.0-amd64，安装方式pip。OK，下面就开始逐条列举所遇问题及解决方法。
1.运行pip install pyautogui后出现如下错误（黄字）：

这个问题比较坑，看log应该是https鉴权，于是上网找了各种方法，都不行，重装python，重启电脑，修改电脑时间都不行，最后发现是自己在调式其他东西打开了fiddler，关闭fiddler就好了，这个是被自己坑了。
2.继续运行pip install pyautogui后提示You are using pip version 10.0.1, however version 19.0.1 is available.
这个是pip版本低了，根据提示运行python -m pip install --upgrade pip即可。
3.继续运行pip install pyautogui出现错误：

这个错误是安装pyautogui过程中遇到的一个核心错误，是安装PyGetWindow过程中出现的，网上搜了一通，最后试了各种方法，就是降低PyGetWindow版本，默认安装的PyAutoGUI-0.9.41，依赖的是PyGetWindow-0.0.4，就是这个PyGetWindow-0.0.4导致了上述问题，于是网上大神说降低PyGetWindow版本，运行pip install PyGetWindow==0.0.1后安装PyGetWindow成功，然后再运行pip install pyautogui，这次，欧耶，成功了。
