[英]How to specify using Python 3's Version of PIP (or why isn't PIP working)
我有一台同時安裝了Python 2.7.6
(默認情況下)和Python 3.4.0
(我自己)的mac。
我認為我可能還安裝了多個版本的PIP。 (當我運行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
帶有1.5.4
版本。
因此,我的問題是:
答:如何確定我是否安裝了多個版本的pip
。
B.如果確實安裝了多個版本,如何指定要使用哪個版本,或者應該將安裝的軟件包放在何處?
我嘗試了這里概述的建議(基本上使用pip-3.4
),但是command not found
所有這些的原因是,當嘗試使用pip
安裝任何軟件包時,甚至只是為了更新( pip install --upgrade pip
),我都會遇到以下錯誤

就像python
被符號鏈接到您的Python 2版本一樣, pip
被符號鏈接到Python 2的pip。
相反,請使用pip3
,該pip3
應引用活動的Python 3安裝(可使用python3
訪問)。 您也可以使用完整的版本名稱,但不能使用破折號: pip3.4
。
