Question

我有两个版本的python-2.7.6＆amp;为python 2.7.6安装了2.7.9和numpy。我无法理解如何为python 2.7.9安装numpy。

当我使用pip2 install --upgrade numpy时，它会安装和更新python 2.7.6。

如何为python 2.7.9特别安装numpy？

*****编辑*****

我想找到python 2.7.9的位置。

如果我输入python或python2，我使用的是python 2.7.9。 which -a python给了我两条路径/usr/bin/python和/usr/local/bin/python，当我使用第一条路径时，它给了我这个输出 - Requirement already satisfied (use --upgrade to upgrade): numpy in /usr/local/lib/python2.7/dist-packages Cleaning up...

如果我使用第二条路径，我会得到这个输出 - /usr/local/bin/python: No module named pip

which -a pip命令提供/usr/local/bin/pip /usr/bin/pip

which -a easy_install提供/usr/local/bin/easy_install /usr/bin/easy_install

which -a python提供/usr/local/bin/python /usr/bin/python

***** EDIT2 *****

我的操作系统是Ubuntu 14.04lts。

/usr/local/bin/pip --version给出pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)。

/usr/bin/pip --version提供pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)

/usr/local/bin/easy_install --version提供setuptools 32.1.2 from /usr/local/lib/python2.7/dist-packages (Python 2.7)

/usr/bin/easy_install --version提供setuptools 3.3

/usr/local/bin/python --version提供Python 2.7.9

/usr/bin/python --version提供Python 2.7.6

***** EDIT3 *****

sudo /usr/local/bin/easy_install pip提供以下输出 -

Answer 1

像这样：

/path/to/python279 -m pip install --user numpy

如果您看到错误No module named pip，请先按照以下说明安装pip：

下载此文件：get_pip.py
执行sudo /path/to/python279 get_pip.py
再试一次/path/to/python279 -m pip install --user numpy

Answer 2

我相信这与你的路径变量有关。目前，我相信你的路径变量指向你安装的Python 2.7.6。检查python的路径变量，并希望将其更改为正确的安装可以解决您的问题。
