大家好，我是讯享网，很高兴认识大家。

mac的坑

$ pip3 install scrapy

讯享网

报错：

讯享网ERROR: Could not install packages due to an EnvironmentError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Max retries exceeded with url: /packages/3b/e4/69b87d7827abf03dea2ead50f347b00a7a3897bc93f6ec3dafa494/Scrapy-1.8.0-py2.py3-none-any.whl (Caused by ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x10a65dca0>, 'Connection to files.pythonhosted.org timed out. (connect timeout=15)'))

直接执行以上指令一般是不行的，最起码（如果你没有使用特殊的上网姿势的话，需要把pip3的源换成国内的镜像源

讯享网

更换pip源

只需要在pip命令使用时，添加 -i 源地址

例如安装scrapy

$ pip3 install scrapy -i https://pypi.mirrors.ustc.edu.cn/simple/

附：常用源
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/
