I'm trying to run heroku and can't seem to get the application to run.
The error log states:

I can see that it can't find the file from my app that lives on my desktop - 'abc.csv' - but I can assure you it is there and that the filename is typed correctly. After all - the app runs perfectly when I run it locally. It's when I try to deploy it when the issue comes up.
回答1:
When you deploy your application to Heroku it will be hosted on a server somewhere that doesn't have access to your local machine, nor the files on your local machine. The application will run fine locally as it is able to see the abc.csv file.
To fix the error, you will need to upload the abc.csv file to Heroku. If you have used git, then you can do this by uploading the csv file to your repository and using a relative path.
