pip各种报错总结

pip各种报错总结

1. pip升级

安装包模块时，提示需要升级 pip
WARNING: You are using pip version 20.2.2; however, version 20.2.3 is available.
You should consider upgrading via the 'c:\users\administrator\appdata\local\programs\python\python36\python.exe -m pip install --upgrade pip' command.

直接输入指令时出现异常
	python -m pip install --upgrade pip
	ValueError: Unable to find resource t64.exe in package pip._vendor.distlib

试了以下几种解决方式
	1. 卸载安装
		python -m pip uninstall pip setuptools
		pip3 install --upgrade pip
	2. 更新
		easy_install -U pip		（一次成功）

升级后，安装指定版本的模块时又出现异常
	ERROR: Could not install packages due to an EnvironmentError: [WinError 32] 另一个程序正在使用此文件，进程无法访问。: 'c:\\users\\administrator\\appdata\\local\\programs\\python\\python
	36\\lib\\site-packages\\setuptools-39.1.0-py3.6.egg'
	Consider using the `--user` option or check the permissions.
	解决：
		只需要python -m pip install --user --upgrade pip==9.0.3
		只需要加一个  --user 在install的后面即可
