EDIT: My .json package

This error is caused by the absence of TypeScript definition files. Make sure your version of angular is correct. These definitions have been removed from automatic inclusion in the recent beta. You can install these definitions locally using typings or tsd .

  • Views: npm install -g typings
  • Tsd: npm install -g tsd

Then run the appropriate commands for the tool to establish the definitions that it complains about.

try

npm remove lite-server

npm install -g at the same time

npm install -g lite-server

npm install -g typescript

I encountered the same problem when running npm install and adding type versions in the devdependencies section of the Package.json file. The problem was solved.

I had a similar problem because I neglected launching

npm install

after the quick start has been started. This solved the problem for me.
