这是我名为udemy的虚拟环境。
yanaz@yanaz-Latitude-E6440:~$ source .venvs/udemy/bin/activate
(udemy) yanaz@yanaz-Latitude-E6440:~$ pip3 freeze
(udemy) yanaz@yanaz-Latitude-E6440:~$ which python3
/home/yanaz/.venvs/udemy/bin/python3
(udemy) yanaz@yanaz-Latitude-E6440:~$ which pip3
/home/yanaz/.venvs/udemy/bin/pip3
这些是我安装的python版本。 apt-get和其他版本安装了Python 3.6：根据本教程https://tecadmin.net/install-python-3-8-ubuntu/
安装了3.7、3.8(udemy) yanaz@yanaz-Latitude-E6440:~$ which python3.6
/usr/bin/python3.6
(udemy) yanaz@yanaz-Latitude-E6440:~$ which python3.8
/usr/local/bin/python3.8
(udemy) yanaz@yanaz-Latitude-E6440:~$ which python3.7
/home/yanaz/.venvs/udemy/bin/python3.7
这是我尝试安装软件包时发生的情况。 Pip的工作方式就像我在虚拟环境之外一样（并且我已经在其中安装了Django）。
(udemy) yanaz@yanaz-Latitude-E6440:~$ sudo pip3 install Django==2.2.4
