我正在创建一个startproject,并且尝试使用命令行迁移默认的Django模式:
manage.py migrate
结果是:"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?"
我正在使用虚拟环境,并且安装了下一个依赖项:
Django==2.1.2
psycopg2==2.7.5
pytz==2018.5
当然,我正在尝试在激活的虚拟环境下进行迁移。
有人知道我的版本兼容性是否有问题?我的PostgreSQL是10。
答案 0 :(得分:2)
这很可能意味着您不是从激活的virtualenv
内运行命令:
C:\> my_venv\Scripts\activate
(my_venv) C:\> (type your command now)
产生的错误消息是if unable to import django.core.management
:
try:
from django.core.management import execute_from_command_line
except ImportError as exc:
raise 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?"
) from exc
您可以使用与错误命令相同的环境进入Python控制台(例如,在您的情况下,在同一控制台窗口中键入python
),然后尝试手动导入该模块,然后{{3} }。
