自系统更新以来 python3 pip 损坏

Question

在 AWS 上更新我的一台 Ubuntu 16.04 机器后，python/pip 似乎损坏了。

ubuntu@host:~$ pip install celery
Traceback (most recent call last):
  File "/home/ubuntu/virtualenvs/myenv/bin/pip", line 7, in <module>
    from pip import main
  File "/home/ubuntu/virtualenvs/myenv/lib/python3.6/site-packages/pip/__init__.py", line 43, in <module>
    from pip.utils import get_installed_distributions, get_prog
  File "/home/ubuntu/virtualenvs/myenv/lib/python3.6/site-packages/pip/utils/__init__.py", line 23, in <module>
    from pip.locations import (
  File "/home/ubuntu/virtualenvs/myenv/lib/python3.6/site-packages/pip/locations.py", line 9, in <module>
    from distutils import sysconfig
  File "/home/ubuntu/virtualenvs/myenv/lib/python3.6/distutils/__init__.py", line 25, in <module>
    from distutils import dist, sysconfig
ImportError: cannot import name 'dist'

ubuntu@host:~$ python3.6 -m pip install celery
Traceback (most recent call last):
  File "/usr/lib/python3.6/runpy.py", line 183, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)

    return _get_module_details(pkg_main_name, error)
  File "/usr/lib/python3.6/runpy.py", line 109, in _get_module_details
    __import__(pkg_name)

ImportError: cannot import name 'dist'

系统运行通过jonathonf/python-3.6 ppa安装的python3.6。在系统更新(apt-get update && apt-get upgrade)之前，一切都按预期进行。我还在尚未更新的其他机器上验证了这一 pip 。

我也没有在新机器的虚拟环境中安装 python3.6，所以我猜最近的版本或更新在这里破坏了什么？

编辑:

我在新的 ubuntu 上安装时也遇到了类似的问题:

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo add-apt-repository jonathonf/python-3.6
$ sudo apt-get update
$ sudo apt-get install python3.6

$ stat /usr/lib/python3.6/distutils/dist.py
stat: cannot stat '/usr/lib/python3.6/distutils/dist.py': No such file or directory

$ ll /usr/lib/python3.6/distutils/

我在一个新的 docker 容器中测试了 PPA，看起来包坏了，所有 distutils 模块在安装后都丢失了。看起来这个包是最近重建的；也许这是一个新问题。

You can open a bug并等待 PPA 维护者修复它，但除此之外，您无能为力。您当然可以尝试摆弄安装:

$ wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
$ tar xvf Python-3.6.5.tgz
$ rsync -av Python-3.6.5/Lib/distutils/ /usr/lib/python3.6/distutils/

当然，这是一个非常脏的东西，因为我不知道那个 PPA 的正确包应该有哪些文件。因此，我不能向您保证这是否对您有用并且不会引入任何新错误，但至少我可以再次运行 pip 并可以安装一个包。
