我嘗試啟動時無法導入Django錯誤

Question

我通常在PC上工作，但開始在我的Mac上處理項目。 我運行Python 3，當我開始一個新項目時，我做了以下事情：

1）在主項目文件夾中，安裝virtualenv並激活它。

2）安裝Django和Gunicorn

3）啟動項目

當我嘗試python3 manage.py startapp www時，我收到一個無法導入Django的錯誤。 以下是終端中的內容：

(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

嘗試使用

python -m pip install django

據我所知，這是最安全的方式

Answer 2

我有同樣的問題，請確保你激活virtualenv，因為一旦你關閉cmd它就不再被激活：

在cmd中使用env\\Scripts\\activate

現在cmd應該有（env）就像這樣： (env) c:\\users\\user\\PROJECT\\..

現在您可以輸入： python manage.py runserver

Answer 3

當我使用Pycharm時，我也遇到了同樣的問題。 我通過添加以下內容解決了

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

to manage.py
