Win10環境下pip升級、換源和BUG
1.pip升級
python -m pip install –upgrade pip
2.換源
在windows資源管理器下鍵入%APPDATA%
新建文件夾pip
進入新建的這個pip文件夾內，新建文件pip.ini，以記事本形式打開，然後敲入
[global]
timeout = 6000
index-url = http://pypi.douban.com/simple
trusted-host = pypi.douban.com
3.BUG
pip安裝任何包都出現問題： Cannot unpack file /tmp/pip-KzJgHD-unpack/simple
報錯：
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
解決：
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
安裝模塊失敗，錯誤如下
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/
解決辦法：
- 訪問
https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient，找到並下載自己需要的包 - CMD切換到存放該文件目錄下，執行
pip install mysqlclient - successful -
運行pip install win32api 和 pip install pywin32
都會提示錯誤，如下：
Could not find a version that satisfies the requirement win32api (from versions: )
No matching distribution found for win32api
改爲
pip install pypiwin32
成功解決。
