tsc: not found on npm start

Although I have installed the dependencies with npm install and can see the package typescript when I do npm list typescript, I still get this error. Only when I npm install -g typescript concurrently I can manage to get npm start working. The angular2-quickstart guide does not state this so I suppose I should not have any problems without installing with the -g option. If -g is a must, then the guide should state this I guess.

vagrant@local:~/angular2-quickstart$ npm start

> angular2-quickstart@1.0.0 start /home/vagrant/angular2-quickstart
> tsc && concurrently "tsc -w" "lite-server" 

sh: 1: tsc: not found

I had to copy typescript from devDependencies to

  "dependencies": {
    "typescript": "^2.4.0"

@olivierto I had the same issue. Try adding this to your Dockerfile

RUN npm install -g tsc \
    && npm install -g concurrently \
    && npm install -g typescript \

For me, that only solved part of the issue. For some reason, npm install did not save the dependencies after installing them. So I had to manually run npm install in the docker container, i.e. docker run angular npm install and then docker run angular npm run typings install.

This is only a workaround, of course. But at least it gets things going. I have yet to find a solution.

Hope that helps!
