npm run clean fails about angular2-essential-training HOT 14 CLOSED

I found a solution. In the tsconfig.json file change
"target": "es5", -> "target": "es6",
This got it to work for me.

from angular2-essential-training.

@GlenQu Can you try the following and let me know if that fixes it:

1. Update the @types in the devDependencies to not have carets:

"@types/core-js": "0.9.34",
"@types/node": "6.0.41",

2. Delete the node_modules directory
3. Run npm cache clean
4. Run npm install

Does the local git repository have to be in my MAMP folder?

Tried changing the target but still no joy for me. Upgraded Node and NPM. Any other solutions?

Hi Justin,

Followed the steps you outlined above but still no joy. I am getting the same error. I appreciate your help on this.

from angular2-essential-training.

Got it working. Now I tried multiple things to get it working. I think ultimately I had to reinstall brackets (which I had uninstalled) then reconfigure the npmrc file.

On the npmrc file I changed my editor variable to use forward slashes instead of backslashes. Restarted cmd and "npm start" worked.
