无法在任何地方的 python 上安装 Django 1.9.6

Question

我试图在任何地方的 python 上安装这个 Django 版本，但我得到了这个错误：

Consider using the `--user` option or check the permissions.

我还想将所有已安装的 python 3.5 库迁移到 python 上的 python3.5 文件夹 lib 上的任何地方，以便我们的网站可以使用 .如果是这种情况，我不需要重新安装这个库，那么我认为我们不需要在任何地方使用 python 来迁移 20 多个 Django 网站。

解决方法在错误信息的最后提示：Consider using the --user option or check the permissions. Just go with --user option while install with pip （记得指定pip应该使用哪个Python版本，否则默认为2.7 ) 它应该可以正常工作。您可能还想阅读this PythonAnywhere help page。
