how to set $PYTHONPATH on OS X Yosemite 10.10.5?

Question

I am using terminal which uses -bash shell

ps -p$$ -ocommand=    --->    -bash

echo $PATH returns:

-bash: /usr/local/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Users/alex_fimm_dev/Desktop/Databases/Mongo/mongodb/bin:/Users/alex_fimm_dev/Desktop/Databases/Mongo/mongodb/bin:/usr/local/Cellar/android-sdk/24.4.1_1/tools:/usr/local/Cellar/android-sdk/24.4.1_1/platform-tools

echo $PYTHONPATH -----> returns nothing

Need to set $PYTHONPATH to a /directory/of/choice

Unsuccessfully I have tried:

export PYTHONPATH=$PATH:/directory/of/choice

Also write to: nano .bash_profile:

export PYTHONPATH=$(/directory/of/choice)

Also I have closed terminal in between to check for changes.

Answer 1

export path in all following files:

private/etc/profile

like:

export PYTHONPATH="/directory/of/choice"

did the trick for me. As described in:
