Replit Failed to Deploy

Problem description:
This project ( works properly in the console, and with ‘Always On’ at the, but will not deploy. I have isolated the problem to two lines of code which the Deployment cannot run.

Expected behavior:
When you hit ‘run’ it should serve the main web page route (‘/’) and should call these two lines of code and display their results, just as it does when you run it in the console.

Actual behavior:
Press ‘Deploy’ and the deployment fails.

Steps to reproduce:
Go to this replit, fork it, and deploy. It produces an error - seems to be a file not found error. However, the same lines of code work when you run the Replit from the console.

The code that will not execute in Deployment is on lines 124 and 125 in

  result1 = subprocess.check_output(["bin/meanings", "salve"], text=True, cwd='whitakers-words') 
  result2 = subprocess.check_output(['./words','~E','man'], text=True, cwd='e2l')

Error message at deployment time:

Would you be able to make this Repl public so that I can fork it and test?

Hello, yes, sorry! I didn’t see your reply until just now. I have made the replit public. Thanks for responding.

Debugging the deployment version is challenging! Using a series of tests and python’s raise to send myself error messages from within deployment, I have been able to ascertain that the directories and files I am trying to call with subprocess do in fact exist, and are in fact executable. Nevertheless python raises the file not found error as indicated above.

Is this forum the right way to ask for technical help with deployments?

Hi @latinlens, I can give you more individual help if you book a debugging session on my calendar: Calendly - Replit Deployments Team
