I want to run third part tool written in python on my ubuntu machine (corgy tool).
However I don't know how to add additional modules to Python path.
cat doc/download.rst
There is currently no setup.py, so you need to manually add
the download directory to your PYTHON_PATH environment variable.
How can I add directory to PYTHON_PATH?
I have tried:
export PYTHON_PATH=/home/user/directory:$PYTHON_PATH && source .bashrc
export PATH=/home/user/directory:$PATH && source .bashrc
python
import sys
sys.path.append("/home/user/directory/")
But when I try to run this tool I get:
Traceback (most recent call last):
File "examples/dotbracket_to_bulge_graph.py", line 4, in <module>
import corgy.graph.bulge_graph as cgb
ImportError: No module named corgy.graph.bulge_graph

Create a .bash_profile in your home directory. Then, add the line
PYTHONPATH=$PYTHONPATH:new_dir
EXPORT $PYTHONPATH
Or even better:
if [ -d "new_dir" ] ; then
PYTHONPATH="$PYTHONPATH:new_dir"
fi
EXPORT $PYTHONPATH
The .bash_profile properties are loaded every time you log in.
The source command is useful if you don't want to log in again.
@fedorqui's answer above was almost good for me, but there is at least one mistake (I am not sure about the export statement in all caps, I am a complete newbie).
There should not be a $ sign preceding PYTHONPATH in the export statement. So the options would be:
Create a .bash_profile in your home directory. Then, add the line
PYTHONPATH=$PYTHONPATH:new_dir export PYTHONPATHOr even better:
if [ -d "new_dir" ] ; then PYTHONPATH="$PYTHONPATH:new_dir" fi export PYTHONPATH
