安装djangorestframework时获取错误-权限被拒绝：'/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尝试上面的命令时，会得到以下错误

Collecting djangorestframework

当我试图升级pip的时候

pip install --upgrade pip

同样，当我使用sudo运行它时，会得到以下错误

Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7eff30658ed0>: Failed to establish a new connection: [Errno -2] Name or service not known',)': /simple/pip/

我该怎么办？还有其他方法来安装djangorestframework吗？

请帮我把这个：

Answer 1

尝试使用虚拟环境。

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

在您的虚拟环境中安装所有的软件包，以避免与其他包发生冲突，这可能解决您的问题。

另一件事是，正如我所看到的，您正在尝试使用python2.7安装它。这是你想要的版本吗？如果您想使用python 3安装它，请执行以下操作：

pip3 install djangorestframework
