三、报错原因(Error reporting reason)

无法获取URL https://pypi.org/simple/pip/ Unable to get URL https://pypi.org/simple/pip/

四、更改为国内的镜像源(Change the mirror's source to domestic)

1、执行命令"pip3 install -i http://pypi.douban.com/simple ipython"发现报错，发现缺少'--trusted-host pypi.douban.com'参数。 Excute the command "pip3 install -i http://pypi.douban.com/simple ipython" found an error and found that the '--trusted-host pypi.douban.com' parameter is missing.

WARNING: The repository located at pypi.douban.com is not a trusted or secure host and is being ignored. If this repository is available via HTTPS we recommend you use HTTPS instead, otherwise you may silence this warning and allow it anyway with '--trusted-host pypi.douban.com'.

2、继续执行命令"pip3 install ipython -i http://pypi.douban.com/simple --trusted-host pypi.douban.com"后，模块安装成功。 Contiune with the command "pip3 install ipython -i http://pypi.douban.com/simple --trusted-host pypi.douban.com",the module is installed successfully.
