Answer 1

Check the "shebang" line of your binstubs (all the files in bin/) they should all look like #!/usr/bin/env ruby for example:

$ head -n 1 bin/*
==> bin/bundle <==
#!/usr/bin/env ruby

==> bin/rails <==
#!/usr/bin/env ruby

==> bin/rake <==
#!/usr/bin/env ruby

==> bin/setup <==
#!/usr/bin/env ruby

==> bin/spring <==
#!/usr/bin/env ruby

==> bin/webpack <==
#!/usr/bin/env ruby

==> bin/webpack-dev-server <==
#!/usr/bin/env ruby

==> bin/yarn <==
#!/usr/bin/env ruby

If you see one that looks like this:

#!/usr/bin/env ruby2.5 

That will cause a problem

Found the problem... the cache in heroku dyno needs to be purged. Heroku made a plugin that can do just that. Install it:

$ heroku plugins:install heroku-repo

And run:

$ heroku repo:purge_cache -a appname

Then commit something or run heroku repo:reset and deploy again.
