python虚拟环境激活

条件：python解释器里已经安装了Django，虚拟环境开启后报错

报错：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?

(new) C:\Users\666666\PycharmProjects\Sec-Tools-master>my_venv\Scripts\activate
系统找不到指定的路径。

原因：虚拟机未激活

操作：

.venv\Scripts\activate
