python - ImportError: No module named 'pandas' (inside virtualenv)

Question

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

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).
