安装djangorestframework时出错 - 权限被拒绝：＆＃39; /usr/lib/python2.7/site-packages/djangorestframework-3.6.3.dist-info'

Question

我想在fedora-25中安装Django rest框架但是当我运行这个命令时：

pip install djangorestframework

我收到了以下错误：

Collecting djangorestframework

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

当我使用 sudo 尝试上述命令时，会出现以下错误

Collecting djangorestframework

当我尝试升级pip时

pip install --upgrade pip

我再次获得权限被拒绝错误，当我使用 sudo 运行时，出现以下错误

我该怎么办？有没有其他方法来安装djangorestframework？

请帮帮我:(

Answer 1

尝试使用virtualenv。

sudo apt-get install python-virtualenv
virtualenv myvenvname // create ur env
source myvenvname/bin/activate // activate it if it isnt already activated

在虚拟环境中安装所有软件包以避免与其他软件包发生冲突，这可能会解决您的问题。

另一件事是，你正试图使用​​python 2.7安装它，正如我所见。这是你想要的版本吗？如果你想使用python 3安装它：

pip3 install djangorestframework
