先向大家展示以下困扰了我好久的问题

C:Userscaiya>pip install pipenv
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with ‘-m pip‘ instead of running pip directly.
Defaulting to user installation because normal site-packages is not writeable

解决办法：pip install keras -i http://pypi.douban.com/simple --trusted-host pypi.douban.com（其中的keras是你需要下载的，根据自己需求自行更改）
