在 linux 中激活 virtualenv 无效

Question

我已经在 Ubuntu 20.04 上安装了 virtualenv。采购 activate 脚本后，它似乎已激活，但安装包似乎将其安装在用户的站点包中而不是虚拟环境中。

(venv) $ python3 -m pip install pytest
Requirement already satisfied: pytest in /home/xxx/.local/lib/python3.8/site-packages (6.2.5)

此外，当我运行 Python 并查看 sys.path:

['', '/usr/lib/python38.zip', '/usr/lib/python3.8', '/usr/lib/python3.8/lib-dynload', '/home/xxx/.local/lib/python3.8/site-packages', '/usr/local/lib/python3.8/dist-packages', '/usr/lib/python3/dist-packages']
