更新Python 3.6的pip3？

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

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

我试着跑

pip3 install --upgrade pip setuptools wheel

但它不会升级Python 3.6的pip.相反,它在Python 3.4中找到pip3并说“满足要求”：

Requirement already up-to-date: pip in /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages
Collecting setuptools
  Downloading setuptools-33.1.1-py2.py3-none-any.whl (472kB)

Collecting wheel
  Downloading wheel-0.29.0-py2.py3-none-any.whl (66kB)
    100% |████████████████████████████████| 71kB 5.7MB/s

    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.我该如何解决这个问题？

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

解决方法:

安装并尝试使用不含virtualenv的Python3.4和3.6并不是一个好主意.

但是,您可以告诉Mac上的终端使用哪个Python点：

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

如果需要在较旧的Python3版本上使用pip,可以将python3.6更改为python3.4.
