python - "PermissionError: [Errno 13] Permission denied: '/usr/lib/python3.5/site-packages '"安装Django

Question

我无法在 Ubuntu 上安装基本的 Django 包。我刚刚删除了 virtualenv 并重新制作了它。 pip3install = pip3 install -r requirements.txt

[mything] cchilders@cchilders-desktop:~/projects/mything (master) 
$ cat requirements.txt 
Django==1.10.1
django-filter
djangorestframework
psycopg2
twilio
ipdb
ipython

左边的mything是一个活跃的virtualenv(我刚刚重制)

Answer 1

您可能会因为忘记将路径放入 Python3 解释器而意外地使用 Python2 重新创建 virtualenv，因此当您执行 pip3 时它指的是系统 Python3。

确保您在 virtualenv 中使用正确的 Python，并确保您使用 pip 创建 virtualenv(是的，这是默认选项，但我们不知道您如何创建虚拟环境)。
