关于conda,pip使用杂项:

Conda

1.镜像源如何恢复默认 :conda config --remove-key channels

2.conda创建虚拟环境: conda create --name python35 python=3.5  提示完成安装包;

3.conda激活环境: conda activate python35;

4.conda退出环境:conda deactivate python35;

5.查看当前虚拟环境的配置: conda list;  (conda update xxx更新,conda uninstall 卸载)

6.查看conda版本:   conda -V;

7.升级conda update conda | conda update anaconda  | conda update ananconda-navigator

8.conda env list 显示所有虚拟环境;

9.conda remove -n(或者name) python35 --all 移除虚拟环境

Pip

1. pip install 包名 -i https://pypi.doubanio.com/simple  在不切换镜像源的情况下,临时下载镜像;

ubuntu下;共存版的pip3升级不可用;

#!/usr/bin/python3
# GENERATED BY DEBIAN

import sys

# Run the main entry point, similarly to how setuptools does it, but because
# we didn't install the actual entry point from setup.py, don't use the
# pkg_resources API.

#from pip import main
#if __name__ == '__main__':
# sys.exit(main())

#2019-02-27 edit
from pip import __main__ # 将main改成__main__
if __name__ == '__main__':
sys.exit(__main__._main())
