熊猫不是在python3工作，而是在蟒蛇工作

Question

我试着在python3经营熊猫。但我得到了以下错误。

user@client3:~/smith/Python$ python3
Python 3.7.0 (default, Oct  3 2018, 21:22:25) 
[GCC 5.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pandas'

所以我试着逃离python，

user@client3:~/smith/Python$ python
Python 2.7.12 (default, Nov 12 2018, 14:36:49) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>> exit()

这里很好。所以我试着为python3安装熊猫，如下所示，

user@client3:~/smith/Python$ sudo apt-get install python3-pandas
Reading package lists... Done

python3-pandas is already the newest version (0.17.1-3ubuntu2).

Use 'sudo apt autoremove' to remove them.

它已经为python3安装了。这里发生何事？为什么它不运行python3？

这应该能行，你看。

pip3 install pandas
