How to set PYTHONPATH for python application. Please check details section for more understanding.

[Anju Thakur]

I am having python application with below structure and setting PYTHONPATH environment veriable but not working for me.

​

Please suggest.​

​

Python Directory ( root dir) ---> sub directory 1

​ ----> sub directory 2 --> subdirA --->.Entryfile.py ( running webserver will run from Entry file.py).

​

​

Command : CF push appname -p pythonDirectory

Command: CF set-env appname PYTHONPATH home/vcap/app

​

​Note ~ I am pushing exploded format of application.

This one is not totally obvious. The `cf set-env` can work, but the buildpack itself is also going to set PYTHONPATH, which will override your `cf set-env`.

 

What you can do to make this work is to add a `.profile` file to the root of your project, i.e. the directory from which you are running `cf push` or in your case where you point `-p` which is `pythonDirectory`. This file will be uploaded with your app & it will be sourced before your app runs.

 

In that file, just put something like this:

export PYTHONPATH="$PYTHONPATH:$HOME"

That will append a path onto the exiting PYTHONPATH set by the buildpack. It add's $HOME which points to `/home/vcap/app` which is the root of the files that you have pushed. If you wanted to point to a subdirectory, just change it to `$HOME/subdir` or whatever path you need in your project.

 

Hope that helps!
