1.添加清华镜像源(参考网址:https://jingyan.baidu.com/article/1876c8527be1c3890a137645.html)
(注:windows下网址不需要单引号括起来,否则会出错)
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes
conda info
conda install scrapy
2.conda换回默认源
conda config --remove-key channels
3.安装opencv
方法一:https://www.cnblogs.com/MrLJC/p/4245925.html
conda install -c https://conda.binstar.org/menpo opencv
但是提示需要python2.7,而不是python3.5,有冲突。
方法二:https://stackoverflow.com/questions/23119413/how-do-i-install-python-opencv-through-conda
conda install --channel https://conda.anaconda.org/menpo opencv3
(注意是import cv2)
