Apache2 和 Django - [wsgi:error] ImportError: cannot import name 'get_version' -> No module named 'django'

Question

我已經在 Django 中建立了一個基本站點，並嘗試使用 Apache 2 為其提供服務，但是在嘗試時出現錯誤：

我安裝的版本是：Apache/2.4.29 (Ubuntu)、mod_wsgi/4.5.17、Python/3.6、Django/2.2.10

我的 apache2 的 djangoproject.conf 是：

<VirtualHost *:80> 
 ServerAdmin admin@customspirit.co
 ServerName customspirit.co 
 DocumentRoot /home/ubuntu/Django 

 <Directory /home/ubuntu/Django>
   Require all granted
 </Directory>  

 Alias /static /home/ubuntu/Django/static_in_env
 
 <Directory /home/ubuntu/Django/static_in_env> 
  Options FollowSymLinks
  Order allow,deny
  Allow from all
  Require all granted 
 </Directory> 

 Alias /media /home/ubuntu/Django/media_root
 
 <Directory /home/ubuntu/Django/media_root> 
  Options FollowSymLinks
  Order allow,deny
  Allow from all
  Require all granted 
 </Directory> 

 
 # adjust the following line to match your Python path 
 WSGIDaemonProcess customspiritco python-home=/home/ubuntu/Django/env python-path=/home/ubuntu/Django
 WSGIProcessGroup customspiritco
 WSGIScriptAlias / /home/ubuntu/Django/customspiritco/wsgi.py 
 
 <Directory /home/ubuntu/Django/custompspiritco>
  <Files wsgi.py>
   Require all granted
  </Files>
 </Directory>

</VirtualHost>

錯誤所在的 init.py 文件如下所示：

from django.utils.version import get_version

VERSION = (2, 2, 10, 'final', 0)

__version__ = get_version(VERSION)


def setup(set_prefix=True):
    """
    Configure the settings (this happens as a side effect of accessing the
    first setting), configure logging and populate the app registry.
    Set the thread-local urlresolvers script prefix if `set_prefix` is True.
    """
    from django.apps import apps
    from django.conf import settings
    from django.urls import set_script_prefix
    from django.utils.log import configure_logging

    configure_logging(settings.LOGGING_CONFIG, settings.LOGGING)
    if set_prefix:
        set_script_prefix(
            '/' if settings.FORCE_SCRIPT_NAME is None else settings.FORCE_SCRIPT_NAME
        )
    apps.populate(settings.INSTALLED_APPS)

wgsi.py 文件如下所示：

 import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'customspiritco.settings.production')

application = get_wsgi_application()

每次我嘗試加載任何內容時都會收到內部服務器錯誤（500），並且錯誤在日志中重復出現。

我現在已經將 Django 重新安裝到 2.2.14 版本，這已經解決了這個問題並帶來了一個新問題

在為我的 python 版本編譯 mod_wgsi 后，此錯誤現在已替換為：

Answer 1

經過數小時的挫折后，通過創建用戶 ubuntu 擁有的新虛擬環境，一切都得到了解決。 以前我一定是使用 sudo 完成的，這導致找不到 Django 模塊的問題
