Question

因此，我尝试在Django中启动一个项目，并根据此处的文档安装了所有内容：https://docs.djangoproject.com/en/3.0/intro/tutorial01/

现在，当我尝试使用命令“ py manage.py runserver”运行服务器时，出现以下错误：

    Traceback (most recent call last):
  File "manage.py", line 10, in main
    from django.core.management import execute_from_command_line
ImportError: No module named 'django'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "manage.py", line 21, in <module>
    main()
  File "manage.py", line 16, in main
    ) from exc
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?

我已经添加了所有必需的环境变量，但我无法弄清这里出了什么问题。任何帮助将是巨大的！：）

Answer 1

尝试使用命令“ python manage.py runserver”运行服务器。检查是否已安装django，并使用命令“ pip Frozen”检查所有已安装的python软件包。如果您在virtalenv中安装了djanjo，请检查virtualenv是否已激活？

Answer 2

确保在您的系统上安装了django。

py -m django

如果该命令导致您遇到错误"No moduled named django"，请尝试以下命令：

py -m pip install django

Answer 3

确保您安装了虚拟环境

py -m pip install virtualenvwrapper-win

workon myvenv

python -m venv myvenv

确保您在正确的目录中以加载虚拟环境

PS C:\Users\taylo\Desktop\django-project\myweb>  . myvenv\Scripts\activate.ps1

您将知道它的激活时间类似于此（myvenv）然后像这样通过pip安装Django

(myvenv) PS C:\Users\taylo\Desktop\django-project\myweb> pip install django

创建您的项目并CD进入

(myvenv) PS C:\Users\taylo\Desktop\django-project\myweb> django-admin startproject myproject
(myvenv) PS C:\Users\taylo\Desktop\django-project\myweb> ls
(myvenv) PS C:\Users\taylo\Desktop\django-project\myweb> cd myproject

要运行本地服务器，文件夹路径应对齐

(myvenv) PS C:\Users\taylo\Desktop\django-project\myweb\myproject> python manage.py runserver

当我尝试运行manage.py runserver时出现错误
