Question

我正在运行python 3.5.2并想运行

>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'numpy'

但是，如果我登记终端

ola@station:~$ pip install numpy
Requirement already satisfied: numpy in /usr/lib/python2.7/dist-packages
ola@station:~$

为什么我有这么多不同的点？

ola@station:~$ pip
pip     pip2    pip2.7  pip3    pip3.4  pip3.5  pip3.6

当我尝试使用pip3.4时，我得到了

ola@station:~$ pip3.5 install numpy
Traceback (most recent call last):
  File "/usr/local/bin/pip3.5", line 6, in <module>
    from pkg_resources import load_entry_point

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pip==8.1.2' distribution was not found and is required by the application

每个版本的python都有一个点子。如果你想为python3.5安装numpy，你可以使用：

pip3.5 install numpy
