[英]How to specify using Python 3's Version of PIP (or why isn't PIP working)
我有一台同时安装了Python 2.7.6
(默认情况下)和Python 3.4.0
(我自己)的mac。
我认为我可能还安装了多个版本的PIP。 (当我运行PIP --version
我pip 1.5.6 from /Library/Python/2.7/site-packages/pip-1.5.6-py2.7.egg (python 2.7)
得到pip 1.5.6 from /Library/Python/2.7/site-packages/pip-1.5.6-py2.7.egg (python 2.7)
但是我知道Python 3
带有1.5.4
版本。
因此,我的问题是:
答:如何确定我是否安装了多个版本的pip
。
B.如果确实安装了多个版本,如何指定要使用哪个版本,或者应该将安装的软件包放在何处?
我尝试了这里概述的建议(基本上使用pip-3.4
),但是command not found
所有这些的原因是,当尝试使用pip
安装任何软件包时,甚至只是为了更新( pip install --upgrade pip
),我都会遇到以下错误
Exception:

就像python
被符号链接到您的Python 2版本一样, pip
被符号链接到Python 2的pip。
相反,请使用pip3
,该pip3
应引用活动的Python 3安装(可使用python3
访问)。 您也可以使用完整的版本名称,但不能使用破折号: pip3.4
。
