python下pip使用bug汇总

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。
