How to install pip on python 3.6, not the default python 2.7?
提问by Fizics
So all day, I have been trying to install pip. I've executed curl https://bootstrap.pypa.io/get-pip.py > get-pip.py. Then sudo python get-pip.py. Next I went to install numpy with sudo pip install numpy. Finally, I opened up the python 3.6 IDLE and I tried to import numpy as npand got an error saying that the module didn't exist.
所以一整天，我一直在尝试安装pip。我已经执行了curl https://bootstrap.pypa.io/get-pip.py > get-pip.py。然后sudo python get-pip.py。接下来我去安装 numpy sudo pip install numpy。最后，我打开了 python 3.6 IDLE 并尝试打开import numpy as np并收到错误消息，说该模块不存在。
I found out that the pip was installed in /Library/Python/2.7/site-packagesso I deleted 2.7 from the directory. I redid the whole process again and got the same error :|
我发现安装了 pip，/Library/Python/2.7/site-packages所以我从目录中删除了 2.7。我再次重做了整个过程并得到了同样的错误：|
I'm wondering if I need to change the default pythonwhich I've been told is not wise. What do I do? I' sure I've deleted everything with python 2.7 in it?
我想知道我是否需要更改默认设置python，我被告知这是不明智的。我该怎么办？我确定我已经删除了包含 python 2.7 的所有内容？

You shouldn't delete the system python. Delete nothing in /Library/Pythonor it's subfolders.
你不应该删除系统python。删除任何内容/Library/Python或其子文件夹。
How did you install python 3.6? Usually, it'll be installed as python3.6with a symlink to python3. pip3is usually installed with it.
你是如何安装python 3.6的？通常，它会通过python3.6符号链接安装到python3. pip3通常与它一起安装。
So what you probably wanted to do was:
所以你可能想做的是：
pip3 install numpy
python3
>>> import numpy
