我使用 Ubuntu 20.04 和 python3.8。
我决定尝试通过创建一个虚拟环境python 3 -m venv venv，发生了以下情况：
python3 -m venv venv
Error: Command '['/root/venv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
当您尝试通过 pip3 安装或删除包时，会出现此错误：
pip3 install django

pip3 版本是
来自 /usr/lib/python3/dist-packages/pip 的 pip 20.0.2（python 3.8）
在此之前，一切正常，我不知道发生了什么。请帮忙！
