End Of Script Output Before Headers Error With Python Script

I've read multiple SO posts regarding this, but can't seem to get this to work. This is my first time working with Python on Apache so I would appreciate the help I can get! So ult

Solution 1:

As per the discussion, there were multiple problems here, which were solved by examining the error.log written by apache and then making appropriate changes.

The first error was:

[Tue Nov 20 17:49:06.593901 2018] [cgi:error] [pid 47854] [client ::1:50462] AH01215: (13)Permission denied: exec of '/Applications/XAMPP/xamppfiles/htdocs/myurl.py' failed: /Applications/XAMPP/xamppfiles/htdocs/myurl.py [Tue Nov 20 17:49:06.595547 2018] [cgi:error] [pid 47854] [client ::1:50462] End of script output before headers: myurl.py

The relevant part here is:

(13)Permission denied: exec of '/Applications/XAMPP/xamppfiles/htdocs/myurl.py' failed

Permissions needed to be set on the .py file being executed to allow the user running the apache process to execute the script. This was done using chmod.

Then, another error was presented:

[Tue Nov 20 17:59:04.720816 2018] [cgi:error] [pid 48715] [client ::1:50555] AH01215: python3: No such file or directory: /Applications/XAMPP/xamppfiles/htdocs/myurl.py [Tue Nov 20 17:59:04.720884 2018] [cgi:error] [pid 48715] [client ::1:50555] End of script output before headers: myurl.py

The relevant part is:

python3:Nosuchfileordirectory

This shows that the system could not find a python3 binary to execute. The correct path to the python3 interpreter had to be determined using which python3. This was then edited into the shebang line of the script.
