在我目前拥有 python3.4 之后，我正在尝试在我的机器上安装 python3.6。但是，安装后尝试在 python3.6 下运行 pip 给我错误:

Traceback (most recent call last):
  File "pip3", line 7, in <module>
    from pip import main
  File "/usr/lib/python3/dist-packages/pip/__init__.py", line 59, in <module>

    import apt_pkg

Original exception was:

    from pip import main
  File "/usr/lib/python3/dist-packages/pip/__init__.py", line 59, in <module>

    register_loader_type(importlib_bootstrap.SourceFileLoader, DefaultProvider)
AttributeError: module 'importlib._bootstrap' has no attribute 'SourceFileLoader'

互联网上有几条关于遇到该错误的评论，但是没有一条包含任何实际的解决建议。有谁知道我该如何解决这个问题？

最佳答案

我设法在不安装任何源代码的情况下解决了这个问题。 这是我所做的:

1. 首先，为 Python3.x 安装 pip(出于某种奇怪的原因我没有安装它...)

   $ sudo apt-get install python3-pip
   

   这是一个旧版本...

   $ pip3 --version
   pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.4)
   

2. ...所以升级到最新的

   $ sudo pip3 install --upgrade pip
   

   现在好多了

   $ sudo pip3 --version
   pip 9.0.1 from /usr/local/lib/python3.4/dist-packages (python 3.4)
   

1. 然后升级virtualenvvwrapper

   $ sudo pip3 install --upgrade virtualenvwrapper
   # ...
   Successfully installed pbr-3.0.1 six-1.10.0 stevedore-1.22.0 virtualenv-15.1.0 virtualenv-clone-0.2.6 virtualenvwrapper-4.7.2
   

2. 现在创建一个新的 virtualenv 工作:

   $ mkvirtualenv -p `which python3.6` <VIRTUALENV_NAME>
   

   pip 也可以:

   $ pip install django
   # ...
   Successfully installed django-1.11.2 pytz-2017.2
   
   $ pip freeze
   Django==1.11.2
   pytz==2017.2
   

注意:现在我意识到这比您要求的要多一些，但是(不知道您到底在哪里失败)我想您在第 2 步之后应该会没事的。

关于python - 在 ubuntu 上将 python3.4 升级到 python3.6 会破坏 pip，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42558133/
