OSX pip总是使用Python2.7，而忽略我的3.6安装

我通过

brew

安装了pip，但我无法让它使用python 3而不是2.7。以下是我认为可能与演示正在发生的事情相关的信息

$ pip -V
pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)
$ pip2 -V
pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)
$ pip3 -V
-bash: pip3: command not found
$ which pip
/usr/local/bin/pip
$ sudo python3 get-pip.py

我尝试了所有我能在网上找到的东西，但运气不好。这个问题的主要症状是，当我使用pip安装软件包时，它总是进入2.7版本（或者由于numpy不受欢迎或诸如此类的原因而无法安装）。

在OSX上，brew（或其他）python 2.7/3单独安装到OSX附带的旧版2.7上。相信我，我说你不想搞砸它

尝试键入pip3

$ pip3 --version   
$ pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)

而pip（适用于2.7）甚至没有安装

$ pip --version
$ zsh: command not found: pip    

即使您尝试：

$ brew install pip

导致

If you meant "pip" specifically:
Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can install 
pip via the instructions at:

作为最后手段：

python3 -m ensurepip

将确保/修复系统拥有它

pip3应位于

/usr/local/bin/pip3

内容包括:

#!/usr/local/opt/python3/bin/python3.6
# EASY-INSTALL-ENTRY-SCRIPT: 'pip==9.0.1','console_scripts','pip3'
__requires__ = 'pip==9.0.1'
import re
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(
        load_entry_point('pip==9.0.1', 'console_scripts', 'pip3')()
    )

我不知道OSX，但on*NIX系统的

pip

是

pip2

，而

pip3

是Python3的

pip

。因此，尝试使用

pip3

brew安装python3

，应为您提供

pip3

pip3命令未找到，我已经做了

brew安装python3

，它只是说它已经安装了。我不知道OS X，但在*NIX系统

pip

是

pip2

，而

pip3

是python3的

pip

。因此，请尝试使用

pip3

brew安装python3

，应为您提供

pip3

pip3命令未找到，我已完成

brew安装python3

，它只是说它已安装。是的，因此pip3命令不存在。运行brew install python3只是说它已经安装。我确实按照那个网站上的说明做了，上面说要求已经更新了。你是通过自制软件安装python3的吗？查看评论的底部。是的，我是通过自制软件安装的。甚至ensurepip命令也会说“需求已经满足”，并指向/usr/local/cillar/…中的路径。。。我认为有东西指向/usr/local/bin/还有其他东西指向/usr/local/cell中的路径。我只是不知道如何排序。你能试试python3-mpip吗？是的，这样pip3命令就不存在了。运行brew install python3只是说它已经安装。我确实按照那个网站上的说明做了，上面说要求已经更新了。你是通过自制软件安装python3的吗？查看评论的底部。是的，我是通过自制软件安装的。甚至ensurepip命令也会说“需求已经满足”，并指向/usr/local/cillar/…中的路径。。。我认为有东西指向/usr/local/bin/还有其他东西指向/usr/local/cell中的路径。我只是不知道该怎么分类你能试试python3-mpip吗
