Django - 无法“迁移”

Question

我目前正在尝试将我的新更改部署到我的 raspberry-pi（激活 virtualenv 时），但我运行 python manage.py migrate 我收到以下错误：

当我尝试运行 sudo python manage.py migrate 时，我收到：

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?

我之前进行过迁移，部署后已经有一段时间了，但没有任何变化，感谢任何故障排除帮助。

编辑：包括我的 virtualenv 已激活

显示 Django 没有安装，你可能因为没有激活虚拟环境而收到错误。 转到存在虚拟环境的特定文件夹并尝试-

source myvenv/bin/activate

将“myvenv”替换为您的虚拟环境名称并尝试迁移。
