Update pip3 for Python 3.6?
提问by user2989813
I just upgraded from Python 3.4 to Python 3.6 using Homebrew.
我刚刚使用 Homebrew 从 Python 3.4 升级到 Python 3.6。
The output states:
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
I tried to run
我试着跑
pip3 install --upgrade pip setuptools wheel
But it does not upgrade pip for Python 3.6. Instead it finds pip3 in in Python 3.4 and says 'requirement satisfied':
但它不会为 Python 3.6 升级 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

When I check the pip version, it is in Python 3.4, not 3.6. How do I resolve this?
当我检查 pip 版本时，它是 Python 3.4，而不是 3.6。我该如何解决？
$ pip3 -V
pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages (python 3.4)

Not a good idea to install and try to use Python3.4 and 3.6 without virtualenv.
安装并尝试使用 Python3.4 和 3.6 而没有virtualenv.
You can however tell the terminal on your mac which Python pip to use with:
但是，您可以告诉 Mac 上的终端使用哪个 Python pip：
python3.6 -m pip install --upgrade pip setuptools wheel
You can change python3.6 to python3.4 if you need to use pip on the older Python3 version.
如果您需要在较旧的 Python3 版本上使用 pip，您可以将 python3.6 更改为 python3.4。

A temporary fix could be:
临时修复可能是：
alias "pip3.6"="python3.6 -m pip "
This will allow you to go pip3.6 install somemoduleor pip3.6 install --upgrade somemodule
这将允许您去pip3.6 install somemodule或pip3.6 install --upgrade somemodule

When I execute python36 -m pip3 install -r requirements.txt, I got the error:
当我执行时python36 -m pip3 install -r requirements.txt，出现错误：
/usr/bin/python36: No module named pip3
My solution is the following:
我的解决方案如下：
python3.6 -m ensurepip
python3.6 -m pip install -r requirements.txt
