ImportError：沒有名為“ numpy”的模塊，但它在那里！ python 3.5

Question

我在這里想念什么？ 有人可以在這里啟發我嗎？

步驟1.我正在嘗試安裝numpy。

aerin @ aerin-HP-Z230-塔式工作站：〜$ sudo pip install numpy

>     Requirement already satisfied: numpy in /usr/local/lib/python3.5/dist-packages
>     You are using pip version 9.0.3, however version 10.0.1 is available.
>     You should consider upgrading via the 'pip install --upgrade pip' command.

第2步。 它說它在/usr/local/lib/python3.5/dist-packages 。 因此，讓我們使用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'

步驟3.您在開玩笑嗎？ 讓我們看看它在哪里導入軟件包。

>import site; site.getsitepackages()

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

您說它在那里，但它給了我一個ImportError！ 如果有人提示我去哪里看，我將不勝感激。 謝謝！

Answer 1

不確定，但我認為您應該嘗試：

sudo pip3 install numpy

如果這不起作用，請嘗試為python2＆3重新安裝numpy

Answer 2

嘗試升級pip，然后重新安裝numpy

sudo pip install --upgrade pip
sudo pip install --reinstall numpy
