importorror:没有名为“numpy”的模块,但它在那里!蟒蛇3.5

我错过了什么?有人能在这里启发我吗?

第一步。我正在安装numpy。

aerin@aerin-hp-z230-tower-workstation:~$sudo pip安装numpy

第二步。好啊。它说它在里面 /usr/local/lib/python3.5/dist-packages 是的。所以让我们使用numpy。

aerin@aerin-HP-Z230-Tower-Workstation:~$ python3
Python 3.5.2 (default, Nov 23 2017, 16:37:01) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.

>import numpy

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

第三步。你在开玩笑吗?让我们看看它在哪里导入包。

>import site; site.getsitepackages()

['/usr/local/lib/python3.5/dist-packages', '/usr/lib/python3/dist-packages', '/usr/lib/python3.5/dist-packages']

你说它在那儿,但它让我很害怕!如果有人告诉我去哪儿看,我会很感激的。谢谢!
