我尝试启动时无法导入Django错误

Question

我通常在PC上工作,但开始在我的Mac上处理项目.我运行Python 3,当我开始一个新项目时,我做了以下事情:

1)在主项目文件夹中,安装virtualenv并激活它.

2)安装Django和Gunicorn

3)启动项目

当我尝试python3 manage.py startapp www时,我收到一个无法导入Django的错误.以下是终端中的内容:

(venv) AB:directory AB$ pip freeze
Django==1.10
gunicorn==19.6.0

(venv) AB:directory AB$ ls
directory   manage.py

(venv) AB:directory AB$ python3 manage.py startpap www

Traceback (most recent call last):
  File "manage.py", line 8, in <module>
    from django.core.management import execute_from_command_line
ImportError: No module named 'django'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "manage.py", line 14, in <module>
    import django
ImportError: No module named 'django'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "manage.py", line 17, in <module>
    "Couldn't import Django. Are you sure it's installed and "
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

Answer 1

尝试使用

python -m pip install django

据我所知,这是最安全的方式

Answer 2

我遇到了同样的问题，请确保您激活了virtualenv，因为一旦关闭cmd，它便不再被激活：

env\Scripts\activate 在cmd中

现在，cmd应该具有（env）如下所示： (env) c:\users\user\PROJECT\..

现在您可以输入： python manage.py runserver
