I downloaded the final plunk for angular.io "tour of heroes" but I'm encountering errors. I'm using the package.json file from the first plunk because a package.json file isn't provided in the final plunk. npm start returns the errors below. This is a fresh install of everything as of tonight. I googled some of these errors and saw a few suggestions which I tried but the errors persist. Any idea how to fix?

In your tsconfig.json you need to add

"exclude": [
    "node_modules",
    "typings"
]

so it won't try to compile node_modules and typings folders.

  • @iJungleBoy Can you give more details on what didn't work and what the error is? – taropoo Jan 18 '17 at 06:34
  • I'll have to look into it again. from what I remember it's a bit of a back-and-forth, I believe it was something like "if you try AoT, it fails, find solution in stack-overflow. apply that, then you get all the errors in the non AoT" or something. but I won't be able to look at it for another week or so. thx for the quick reply – iJungleBoy Jan 19 '17 at 07:23
  • Hmm I am not sure, have to see the entire log, let me know I guess :) and np! – taropoo Jan 19 '17 at 20:51

  1. Remove @types/core-js by running the following command: "npm uninstall @types/core-js"

  2. Then install core-js by running the following command: "npm install core-js --save"
