Ubuntu 20.04 升级后 Python virtualenv 问题

我将系统更新至 Ubuntu 20.04

我已经在我的 Python 虚拟环境中Python 3.6.7运行virtualenv它了。virtualenvwrapper

更新后

我可以检查已创建的虚拟环境列表，但是当我尝试创建新的虚拟环境时mkvirtualenv -p python newenv

我收到此消息

Traceback (most recent call last):
  File "/home/abcd/.local/bin/virtualenv", line 7, in <module>
    from virtualenv import main
ImportError: cannot import name 'main' from 'virtualenv' (/usr/lib/python3/dist-packages/virtualenv/__init__.py)

然后我检查了更新后的python版本Python 3.8.5

我检查了main里面virtualenvPython 3.8.5

Python 3.8.5 (default, Jan 27 2021, 15:41:15) 
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from virtualenv import main
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'main' from 'virtualenv' (/usr/lib/python3/dist-packages/virtualenv/__init__.py)
>>>

我尝试安装virtualenv并virtualwrapperPython 3.8.5

python -m pip install virtualenv virtualenvwrapper

因为我的默认Python版本是3.8.5更新后

即使安装后我也收到同样的消息ImportError: cannot import name 'main' from 'virtualenv'

我找到了这个帖子在 Ubuntu 20.04 上创建 Python 3.6 虚拟环境的问题

按照建议安装Python 3.6.7最受欢迎的答案

cd opt
sudo wget https://www.python.org/ftp/python/3.6.7/Python-3.6.7.tgz
sudo tar -xvf Python-3.6.7.tgz
cd Python-3.6.7

make clean

sudo ./configure

sudo make
sudo make install

更新了我的bashrc

export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_VIRTUALENV=/home/abcd/.local/bin/virtualenv

# Virtual Environment Wrapper
source /home/abcd/.local/bin/virtualenvwrapper.sh

对于 VIRTUALENVWRAPPER_PYTHON

which python3
/usr/local/bin/python3

对于 VIRTUALENVWRAPPER_VIRTUALENV

sudo find / -name "virtualenv"
/home/abcd/.local/bin/virtualenv

对于virtualenvwrapper.sh

sudo find / -name "virtualenvwrapper.sh"
/home/abcd/.local/bin/virtualenvwrapper.sh

source ~/.bashrc

Python3 -V显示器Python 3.6.7

Python -V显示器Python 3.8.5

安装virtualenv并virtualenvwrapper用于Python 3.6.7​Python3 -m pip install virtualenv virtualenvwrapper

现在我尝试使用创建虚拟环境Python 3.6.7

mkvirtualenv -p python3 newenv

我收到了同样的消息

Traceback (most recent call last):
  File "/home/abcd/.local/bin/virtualenv", line 7, in <module>
    from virtualenv import main
ImportError: cannot import name 'main' from 'virtualenv' (/usr/lib/python3/dist-packages/virtualenv/__init__.py)

当我进去Python 3.6.7检查Python 3.8.5from virtualenv import main

Python 3.8.5 (default, Jan 27 2021, 15:41:15) 
[GCC 9.3.0] on linux

>>> 

Python 3.6.7 (default, May 26 2021, 09:24:09)

这里的解决方案是什么？
