How to fix "Exception: Install 'email_validator' for email validation support" in Heroku?

Question

When I open my app in Heroku, it gives me this error:

2022-04-10T19:49:02.067488+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=likeblogs.herokuapp.com request_id=765d2963-1ae8-47f4-958f-672ee4a7d99a fwd="189.102.131.238" dyno= connect= service= status=503 bytes= protocol=https

I have already declared the requirements.txt and set gunicorn and in my Procfile like this :

web: gunicorn main.py:app

I have these errors:

Why would you switch from nice, text-based content to an image? [Please don't post screenshots of text](https://meta.stackoverflow.com/a/285557/354577).

If you select it and click the `{}` button or Ctrl+K the code block will be indented by four spaces, which will cause it to be rendered as code. — ChrisGPT was on strike, Apr 10 '22 at 22:51
Either way, that's just the last few lines of the error output. Please show us _all of it_. — ChrisGPT was on strike, Apr 10 '22 at 22:52
The clipped error message says "*Exception: Install 'email_validator' for email validation support*". Have you tried that? See related: [WTForms: Install 'email_validator' for email validation support](https://stackoverflow.com/q/61356834/2745495) — Gino Mempin, Apr 10 '22 at 23:19

Maybe you mean

web: gunicorn main:app

The .py shouldn't be included: the format is $(MODULE_NAME):$(VARIABLE_NAME).

Maybe it's an issue with file paths. What do the logs tell you? – Tim Apr 10 '22 at 21:45

Have you included `email_validator` in requirements.txt? – Tim Apr 10 '22 at 22:04
I'll see in a minute – torzin Apr 10 '22 at 22:08
no i din't include – torzin Apr 10 '22 at 22:10
You'll need to include it. The error message says you simply need to install it, and you can do so by adding it to requirements.txt. – Tim Apr 10 '22 at 22:17
