问题描述
我从19.10升级到Ubuntu 20.04,现在我不能使用pip.
I upgraded to Ubuntu 20.04 from 19.10 and now I cannot use pip.
zeno:~$ pip --version
Command 'pip' not found, but there are 18 similar ones.
已安装Python:
zeno:~$ python3 --version
Python 3.8.2
但是如果我尝试设置点子,我会得到:

我迷路了.感谢您的帮助
I am lost. Thanks for any help
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:
I use venv to create virtual environments. When no venv is activated, I can use 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:
but if I activate a venv, it does not work:
(.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.
Thank you for your suggestions and continued help.
更新
我尝试删除venv并制作一个新的venv,但是我似乎需要做点子操作才能做到这一点:
I tried deleting the venv and making a new one, but it seems I need pip working in order to do that:
zeno:~/Desktop/tetris$ python3 -m venv .tetris
给予:
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']
推荐答案
有时,在操作系统升级后,您需要重新安装软件包.试试:
Sometimes after OS upgrade you need to reinstall packages. Try:
sudo apt install --reinstall python3-pip
