问题
I created a virtual environment named quora for python. I installed wheel and then pandas as instructed. I cant get pandas to work for some reason. Can someone help me. I have tried all the other solutions available to similar questions on this website. Still no use.
(quora) (jessie)griffith@localhost:~/environments$ sudo pip install wheel
Requirement already satisfied: wheel in /usr/lib/python2.7/dist-packages
(quora) (jessie)griffith@localhost:~/environments$ sudo pip install pandas
Requirement already satisfied: pandas in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied: pytz>=2011k in /usr/local/lib/python2.7/dist-packages (from pandas)
Requirement already satisfied: numpy>=1.7.0 in /usr/local/lib/python2.7/dist-packages (from pandas)
Requirement already satisfied: python-dateutil in /usr/local/lib/python2.7/dist-packages (from pandas)
Requirement already satisfied: six>=1.5 in /usr/lib/python2.7/dist-packages (from python-dateutil->pandas)
(quora) (jessie)griffith@localhost:~/environments$ python getdata.py
Traceback (most recent call last):
File "getdata.py", line 2, in <module>
import pandas as pd
ImportError: No module named 'pandas'

Don't use sudo in a virtualenv — sudo pip install installs packages into global site-packages, not in virtualenv.
Either install pandas in the virtual environment (pip install after activating venv) or enable access to the global packages (recreate venv with option --system-site-packages or use command toggleglobalsitepackages from virtualenvwrapper).

I had this problem in a virtualenv with pip3 and pandas, tried all these previous answers, none of which actually work. but you can use easy_install pandas. et voilà.

Check "which python" you are running using that command. You may need to export PATH to the python env instead of your default python which might be /usr/lib/bin. It might be installed in your quora env but the python that is being picked up is different and that doesn't have pandas
