Ember serve doesn't work (Error: Couldn't find preset “es2015”)

Question

I am building a web app using Ember. I created the project with ember new test-app and have made no changes to the generated files. When I run ember serve, I immediately receive the following error:

The Broccoli Plugin: [BroccoliMergeTrees: Addon#compileAddon(ember-welcome-page) ] failed with:

I referred to this question for help, but I still received the same error after trying the solution.

I am running ember-cli v2.16.2 and node v8.9.0 on macOS High Sierra. In my node installation, the only three global modules I have installed are bower, broccoli-cli, and ember-cli.

Please do clean reinstall of ember-cli package.

npm uninstall -g ember-cli
npm cache clean --force
npm install -g ember-cli

Then run your ember new command once again and test it.
