Question

我通常在PC上工作但是开始在我的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，安装了virtualenv并激活它。

2）安装Django和Gunicorn

3）startproject

当我尝试python3 manage.py startapp www时出现无法导入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，请确保你激活了virtualenv，因为一旦你关闭cmd它就不再被激活了：

cmd中的

env\Scripts\activate

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

Answer 3

使用Pycharm时，我也遇到同样的问题。我通过添加来解决它：

import sys
  sys.path.append('/Users/et/PycharmProjects/Jieba_Analyzer/venv/lib/python3.6/site-packages')

to manage.py

当我尝试启动应用程序时无法导入Django错误
