自系统更新以来,python3点破了

Question

在AWS上更新我的一台Ubuntu 16.04机器后,python/pip似乎被破坏了.

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)

系统运行通过jonathonf/python-3.6ppa 安装的python3.6 .在系统更新(apt-get update && apt-get upgrade)之前,一切都按预期工作.我还在其他尚未更新的机器上验证了这一点.

我也没有在新机器上的虚拟环境中安装python3.6的运气,所以我猜最近的发布或更新在这里打破了一些东西？

编辑:

在新的ubuntu上安装时我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/

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

您可以打开一个错误并等待 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，因为我不知道该 PPA 的正确包应该有哪些文件。因此，我不能向您保证这是否适合您并且不会引入任何新错误，但至少我可以pip再次运行并可以安装软件包。
