python安装报错问题汇总（SSL: CERTIFICATE_

一、报错问题

Could not fetch URL https://pypi.python.org/simple/django/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749) - skipping Could not find a version that satisfies the requirement django (from versions:)

二、解决方式

1、安装命令：python3 -m pip install --trusted-host pypi.python.org django

2、安装命令：python3 -m pip install -i https://pypi.douban.com/simple django

3、pip install -i https://pypi.douban.com/simple django

如果还是提示该报错信息，检查一下本机的Fiddler 是不是开启状态，该软件需要保持关闭状态（亲测有效）。。。。
