Laravel to Python RuntimeError: Can't determine home directory

Question

In my Laravel (php) product we are calling the python script. While I run this script in command prompt it's working fine. But from Laravel controller it raised an error.

Error Output:

Traceback (most recent call last):

We are using laravel process features to execute this python script.

Please let me know how to resolve this issue.

I was having the same problem as you do, I could solved it out by setting up the variable manually as the problem was that

os.environ['HOME']

was being none, which was causing the problem

So you can set it up manually with this code

os.environ['HOME'] = 'C:/Python'

Check that you are using "/" and not "\" when setting up, otherwise it will give you an error.

It solved my problem. I'm using Apache as well and calling a Python script and also make sure that your code has the path of python on the top of your script

#!C:\Python\python.exe

This solution works with Pydev too. I got a `RuntimeError: Can't determine home directory` error when importing matplotlib within Pydev but not when using Anaconda's console. Manually setting `HOME` fixes it. — Leonardo, Mar 25 '20 at 15:07

Attempted to do something similiar [export HOMEPATH="/c/Users/jason/Documents/GitHub/DAIN/my_package"] failed to work – Jun 03 '22 at 06:22
