通过pip和HomeBrew实现Mac上的Django Python -入门

Question

我正试图开始使用Django进行Django网络编程，所以我首先安装了pip (通过HomeBrew)，现在安装了最新版本的Django，但是发生了以下情况，我不知道接下来发生了什么错误或者应该做什么。有人能帮我理解一下正在发生什么吗?我需要做什么?我应该发出什么命令来解决这个问题，等等……

$ pip --version
pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)

$ pip install Django==1.11.7

Answer 1

这可能是因为您的用户帐户对Library文件夹没有一些权限。

使用

sudo pip install Django==1.11.7

替代方式

您也可以使用

pip install --user Django

它按照用户安装方案安装Django。这页面说：

该方案是为用户设计的最方便的解决方案，没有对全局站点包目录的写权限，也不想安装到其中.文件将被安装到基座的子目录中。

但是，我认为您正在做的事情并不被认为是最佳实践。
