我从19.10升级到Ubuntu 20.04，现在无法使用pip。
zeno:~$ pip --version
Command 'pip' not found, but there are 18 similar ones.
Python已安装:
zeno:~$ python3 --version
Python 3.8.2
但是，如果我尝试安装intatll pip ，则会得到以下信息:
zeno:~/Desktop/tetris$ sudo apt install python3-pip
Reading package lists... Done
Building dependency tree
Reading state information... Done
python3-pip is already the newest version (20.0.2-5ubuntu1).
The following packages were automatically installed and are no longer required:

我搞不清楚了。谢谢你的帮助
更新
我使用venv创建虚拟环境。没有激活任何venv时，我可以使用pip3:
zeno:~/Desktop/tetris$ pip3 -V
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
但是，如果我激活venv，它将无法正常工作:
(.tetris) zeno:~/Desktop/tetris$ pip3
Traceback (most recent call last):
File "/home/zeno/Desktop/tetris/.tetris/bin/pip3", line 6, in <module>
from pip._internal import main
ModuleNotFoundError: No module named 'pip'
感谢您的建议和持续的帮助。
更新
我尝试删除venv并制作一个新的venv，但看来我需要做 pip 操作才能做到这一 pip :
zeno:~/Desktop/tetris$ python3 -m venv .tetris
给出:
The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.
apt-get install python3-venv
You may need to use sudo with that command. After installing the python3-venv
package, recreate your virtual environment.
Failing command: ['/home/zeno/Desktop/tetris/.tetris/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']
最佳答案
有时，在操作系统升级后，您需要重新安装软件包。尝试:
sudo apt install --reinstall python3-pip
