You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

即使使用管理员权限也会出现此问题。

Answer 1

使用管理员权限打开您的cmd。右键单击图标，然后选择以管理员身份打开。

在您需要.content:before { content: ""; position: fixed; left: 0; right: 0; z-index: 0; display: block; background-image: url("/img/dark-abstract-hd-wallpapers.jpg"); background-size: cover; data-role: fitImage; width: 100%; height: 100%; -webkit-filter: blur(5px); -moz-filter: blur(5px); -o-filter: blur(5px); -ms-filter: blur(5px); filter: blur(5px); } .content { position: fixed; left: 0; right: 0; z-index: 0; margin-left: 20px; margin-right: 20px; } #main { width: 100%; position: relative; margin: 0 auto; line-height: 1.4em; } @media only screen and (max-width: 479px) { #main { width: 90%; } }的默认python环境中升级PIP，即在Windows术语中，您必须以管理员模式启动命令提示符。事实上，不建议这样做。

如果您设置了virtualenv，则无需使用sudo /'Windows管理员。设置Python virtualenv 是python最佳做法，因此您可以分离单个项目所需的pip包。对于Windows，它是similar setup。

尽管如此，如果你的PC有足够的RAM，只需安装Virtualbox并部署ubuntu即可。这样，您不需要处理开发人员忽视的Windows python包安装/升级（尽管所有python包都假设开箱即用）。
