n8n - python packages

[simong]

Hi, I need to install a python package via pip for the code node. But there is a problem with the read only file system from cloudron. Is there a workaround?

Have you seen https://docs.cloudron.io/apps/n8n/#custom-node-modules already?

[joseph]

Don't mind me, you want custom pip modules and not custom node modules. Does upstream support this? If you have a doc link, we can adjust our package accordingly.

You can often install things to the /app/data location manually if you can set the right env variables.

try:

export HOME=/app/data

then run the pip install
