If it's really gone, don't sweat it. Virtual environments are completely expendable – it'll turn up. For now, just make another, and be sure you create it in your project's root directory this time.

您实际上通常不需要使用 vscode 激活 venv.只需 cd 进入项目根目录并使用 code . 打开 vscode.激活的环境将出现在页脚的同一位置.

You actually usually don't need to activate a venv with vscode. Just cd into the project root directory and open vscode with code .. The activated envionment will appear in that same spot in the footer.
