Errors when using "npm start" (in MacOS)

I have been trying for sometime already to just run "npm start" for an old app developed with EmberJs but I get several errors. I had tried the following:

1. Uninstall, cache clean, install Ember-cli
2. Remove the "node_modules" and run "npm install"
3. Updating ember-cli-babel
4. And some few others like updating / removing packages

I haven't open this project for around 3 years so I am pretty sure there are new updates that probably I need to follow but not sure what else to do after the list I just mentioned above.

I uploaded what I get when running "npm start". Any guidance, help, or suggestion I would appreciate it! Thanks in advance!!
