无法在 Ubuntu 18.04 上使用 pip 安装“environs”

Question

当我尝试安装environs4.1.0 时，起诉：

pip3 install environs==4.1.0

我得到：

Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
  File "/usr/lib/python3/dist-packages/pip/__init__.py", line 29, in <module>
    from pip.utils import get_installed_distributions, get_prog
  File "/usr/lib/python3/dist-packages/pip/utils/__init__.py", line 23, in <module>
    from pip.locations import (
  File "/usr/lib/python3/dist-packages/pip/locations.py", line 9, in <module>
    from distutils import sysconfig

运行sudo apt update不会改变任何事情。我也尝试过 sudo apt install environs，sudo apt install environs==4.1.0 但它说：

E: Unable to locate package environs

python3 -m pip install environs==4.1.0输出：

Traceback (most recent call last):
  File "/usr/lib/python3.9/runpy.py", line 188, in _run_module_as_main mod_name, mod_spec, code = _get_module_details(mod_name, _Error)
  File "/usr/lib/python3.9/runpy.py", line 147, in _get_module_details return _get_module_details(pkg_main_name, error)

  File "/usr/lib/python3/dist-packages/pip/locations.py", line 9, in <module>
    from distutils import sysconfig
  ImportError: cannot import name 'sysconfig' from 'distutils' (/usr/lib/python3.9/distutils/__init__.py)

我应该怎么办？
