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

当我尝试运行sudo python manage.py migrate时，我会收到：
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?
我以前运行过迁移，自部署以来已经过了一段时间，但没有任何改变，任何疑难解答帮助都很受欢迎。
编辑：包括我的virtualenv已激活
答案 0 :(得分：0)
它显示未安装Django，您可能因为未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
替换＆＃39; myvenv ＆＃39;使用您的虚拟环境名称并尝试迁移。
