I'm trying out the official 5 Min Quickstart about angular 2 for Typescript. I followed all steps and when I run npm start
it did pop up the expected My First Angular 2 App
message on my firefox browser.
However, when I checked the console, I found error messages:
Error: watch node_modules/angular2/es6/dev/src/common/directives/ng_if.js ENOSPC
I don't know if it's related to the warning message I received earlier when I run npm install
on the root folder of the project:
npm WARN install Couldn't install optional dependency: Unsupported
npm WARN EPACKAGEJSON [email protected] No description
npm WARN EPACKAGEJSON [email protected] No repository field.
Can someone tell me what's wrong my approach? A more detailed console output looks like this:

I resolved this by increasing the amount of inotify watchers :
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
