-bash: mkvirtualenv: command not found

[harrywang]

I setup my Mac correctly by following the tutorial but ran into the following error

$ mkvirtualenv DataVizProj
-bash: mkvirtualenv: command not found

then, I ran (previously ran once)

source /usr/local/bin/virtualenvwrapper.sh

then, it works. Do I have to run source everytime I use mkvirtualenv?

thanks a lot for your help.

Solved:

add

source /usr/local/bin/virtualenvwrapper.sh

to .bash_profile and

source .bash_profile
