I can't solve this problem, could it be my mistake?

Did you add the Python buildpack on your app? You can try checking it on the site or just run $ heroku buildpacks -app <your app name> if its not in there add it by running $ heroku buildpacks:set heroku/python -a <your app name>

CodePudding user response：

Your screenshot shows a file that appears to be called parser_twitter, but Windows recognizes it as a Python file. Similarly, chromedriver doesn't have a visible extension, but Windows recognizes it as an executable.

This suggests that Windows Explorer is hiding known file extensions. Those files are almost certainly really named parser_twitter.py and chromedriver.exe.

But your requirements.txt and runtime.txt file extensions are visible. That would mean they are actually called requirements.txt.txt and runtime.txt.txt.

I suggest turning off that "feature" so you can see what your files are actually called:

In File Explorer under View, in the Show/hide group, select the File name extensions check box.

Rename those files to remove the duplicate file extensions, commit, and redeploy.

Aside: If you have committed the chromedriver.exe file you're going to find that it doesn't work on Heroku. See Selenium web driver can't open browser on Heroku, for example.
