在ubuntu上将python3.4升级到python3.6会破坏pip

前端之家收集整理的这篇文章主要介绍了在ubuntu上将python3.4升级到python3.6会破坏pip前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我目前有python3.4后,我正试图在我的机器上安装python3.6。但是,安装后试图在python3.6下运行pip给我错误
Traceback (most recent call last):

Original exception was:

  File "pip3",DefaultProvider)
AttributeError: module 'importlib._bootstrap' has no attribute 'SourceFileLoader'

互联网上有几条关于遇到错误评论,但是,它们都没有包含任何实际的解决方案建议。有谁知道如何解决这个问题?

我设法解决了它,没有从源头安装任何东西。
这是我做的:

>首先,为Python3.x安装pip(出于一些奇怪的原因,我没有它…)

$ sudo apt-get install python3-pip

这是旧版本……

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

> …所以升级到最新版本

$ 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)

>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

>现在创建一个新的virtualenv工作:

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

点子也有效:

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

$ pip freeze
Django==1.11.2
pytz==2017.2

注意:现在我意识到它比你要求的要多一点,但是(不知道你到底在哪里失败了)我猜你应该在第2步之后做好。
