manage.py“Couldn't import Django”报错的问题解决

问题分析：

在pyharm中项目可以正常运行但是在终端 终端输入python manage.py runserver首次测试项目时，出现了无法引用Django的错误。

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?

可能出现的问题：

• 有不同版本的Python，当前项目使用了没有安装Django的Python。
• 创建的虚拟环境时，没有导入之前下载的包，导致在环境下搜索不到Django。
• Django版本过低。

解决方案：

将pyharm文件夹下site-packages中所有的文件复制一份到python的Lib文件夹 虚拟环境中。

然后就可以在终端跑起你的项目咯
