PS：以下操作全部基于win10 64位操作系统
pip安装任何包都出现问题： Cannot unpack file /tmp/pip-KzJgHD-unpack/simple
报错：
Cannot unpack file /tmp/pip-KzJgHD-unpack/simple (downloaded from /tmp/pip-M1hKq2-build, content-type: text/html; charset=utf-8); cannot detect archive format
Cannot determine archive format of /tmp/pip-M1hKq2-build
解决：
需要添加 --extra-index-url 如：
pip install --extra-index-url http://mirrors.aliyun.com/pypi/simple/ config
--extra-index-url <url> Extra URLs of package indexes to use in addition to --index-url. Should follow the same rules as --index-url
安装模块失败，错误如下
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/
解决办法：
- 访问
https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient，找到并下载自己需要的包 - CMD切换到存放该文件目录下，执行
pip install mysqlclient - successful -
运行pip install win32api 和 pip install pywin32
都会提示错误，如下：
Could not find a version that satisfies the requirement win32api (from versions: )
No matching distribution found for win32api
改为
pip install pypiwin32
成功解决。
