更新适用于Python 3.6的pip3? [英] Update pip3 for Python 3.6?

问题描述

我刚刚使用Homebrew从Python 3.4升级到Python 3.6.

I just upgraded from Python 3.4 to Python 3.6 using Homebrew.

输出状态:

Pip, setuptools, and wheel have been installed. To update them
  pip3 install --upgrade pip setuptools wheel
You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.6/site-packages

我尝试运行

pip3 install --upgrade pip setuptools wheel

但是它不会升级适用于Python 3.6的pip.相反，它在Python 3.4中找到pip3并说要求已满足":

But it does not upgrade pip for Python 3.6. Instead it finds pip3 in in Python 3.4 and says 'requirement satisfied':

Requirement already up-to-date: pip in /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages
Collecting setuptools

    Uninstalling setuptools-12.0.5:
      Successfully uninstalled setuptools-12.0.5
Successfully installed setuptools-33.1.1 wheel-0.29.0

当我检查pip版本时，它是在Python 3.4中，而不是3.6中.我该如何解决?

When I check the pip version, it is in Python 3.4, not 3.6. How do I resolve this?

$ pip3 -V
pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages (python 3.4)

推荐答案

如果没有但是，您可以告诉Mac上的终端使用哪个Python点:

You can however tell the terminal on your mac which Python pip to use with:

python3.6 -m pip install --upgrade pip setuptools wheel

如果需要在旧版本的Python3上使用pip，可以将python3.6更改为python3.4.

You can change python3.6 to python3.4 if you need to use pip on the older Python3 version.
