How to configure custom PYTHONPATH with VM and PyCharm? - intellij-idea

Question

I am using IntelliJ with the Python plugin and the Remote Interpreter feature to communicate with my Vagrant VM. It sets up the remote interpreter correctly to use my VM's interpreter. But, I use a custom PYTHONPATH in my VM, and I would like IntelliJ to recognize that path and include the modules in that path when developing.
How do I configure IntelliJ/PyCharm's remote interpreter to use a custom PYTHONPATH on the VM?

Answer 1

For PyCharm 5 (or 2016.1), you can:
select Preferences > Project Interpreter
to the right of interpreter selector there is a "..." button, click it
select "more..."
pop up a new "Project Interpreters" window
select the rightest button (named "show paths for the selected interpreter")
pop up a "Interpreter Paths" window
click the "+" buttom > select your desired PYTHONPATH directory (the folder which contains python modules) and click OK
Done! Enjoy it!

Instructions for editing your PYTHONPATH or fixing import resolution problems for code inspection are as follows:
Open Preferences (On a Mac the keyboard short cut is ⌘,).
Look for Project Structure in the sidebar on the left under Project: Your Project Name
Add or remove modules on the right sidebar
EDIT: I have updated this screen shot for PyCharm 4.5

To me the solution was to go to
Run > Edit Configuration > Defaults > Python
then manage the
"Add content roots to PYTHONPATH" and
"Add source root to PYTHONPATH"
checkboxes, as well as setting the "Working directory" field.
If you have set up your own Run/Debug Configurations then you might want to go to
Run > Edit Configuration > Python > [Whatever you called your config]
and edit it there.
My problem was that I wanted to have my whole repository included in my PyCharm 2016.2 project, but only a subfolder was the actual python source code root. I added it as "Source Root" by right clicking the folder then
Mark directory as > Source Root
Then unchecking "Add content roots to PYTHONPATH" and checking "Add source root to PYTHONPATH" in the Run/Debug config menu. I then checked the folder pathing by doing:
import sys
logger.info(sys.path)
This outputed:
[
'/usr/local/my_project_root/my_sources_root',
'/usr/local/my_project_root/my_sources_root',
'/usr/lib/python3.4', '/usr/lib/python3.4/plat-x86_64-linux-gnu',
'/usr/lib/python3.4/lib-dynload',
'/usr/local/lib/python3.4/dist-packages',
'/usr/lib/python3/dist-packages'
]
However, without the fix it said:
[
'/usr/local/my_project_root/my_sources_root',
'/usr/local/my_project_root', <-- NOT WANTED
'/usr/lib/python3.4',
'/usr/lib/python3.4/plat-x86_64-linux-gnu',
'/usr/lib/python3.4/lib-dynload',
'/usr/local/lib/python3.4/dist-packages',
'/usr/lib/python3/dist-packages'
]
Which meant I got the project root folder included. This messed up the pathing for me.

Answer 4

This was done with PyCharm Community 2019.1
Go to Project Settings
Go to Project Structure and right click on the directory you want to add and click "Sources"
This should add the directory to your pythonpath

Answer 5

An update to the correct answer phil provided, for more recent versions of Pycharm (e.g. 2019.2).
Go to File > Settings and find your project, then select Project Interpreter. Now click the button with a cog to the right of the selected project interpreter (used to be a ...).
From the drop-down menu select Show All... and in the dialog that opens click the icon with a folder and two sub-folders.
You are presented with a dialog with the current interpreter paths, click on + to add one more.

In my experience, using a PYTHONPATH variable at all is usually the wrong approach, because it does not play nicely with VENV on windows. PYTHON on loading will prepare the path by prepending PYTHONPATH to the path, which can result in your carefully prepared Venv preferentially fetching global site packages.
Instead of using PYTHON path, include a pythonpath.pth file in the relevant site-packages directory (although beware custom pythons occasionally look for them in different locations, e.g. enthought looks in the same directory as python.exe for its .pth files) with each virtual environment. This will act like a PYTHONPATH only it will be specific to the python installation, so you can have a separate one for each python installation/environment. Pycharm integrates strongly with VENV if you just go to yse the VENV's python as your python installation.
See e.g. this SO question for more details on .pth files....

Latest 12/2019 selections for PYTHONPATH for a given interpreter.

Answer 8

Well you can do this by going to the interpreter's dialogue box. Click on the interpreter that you are using, and underneath it, you should see two tabs, one called Packages, and the other called Path.
Click on Path, and add your VM path to it.

In Intellij v2017.2 you can go to:
run > edit configurations > click ... next to the field 'Environment variables' > click the green + sign
Name= PYTHONPATH
value= your_python_path

Pycharm 2020.3.3 CE ZorinOS(Linux) File>Settings > Project Structure > {select the folder} > Mark as Source(blue folder icon) > Apply
To verify:
import sys
print(sys.path)
Selected path should be listed here.
