I know Angular2 beta has just been released but I can't reproduce the steps from their official site tutorial ( https://angular.io/guide/quickstart ). Maybe someone has had similar issues and knows what to do in order to fix the this? When I try to start the application with npm start command I get output like this:
0 info it worked if it ends with ok 1 verbose cli [ 'node', '/usr/local/bin/npm', 'start' ] 2 info using [email protected] 3 info using [email protected] 4 verbose run-script [ 'prestart', 'start', 'poststart' ] 5 info prestart [email protected] 6 info start [email protected] 7 verbose unsafe-perm in lifecycle true 8 info [email protected] Failed to exec start script 9 verbose stack Error: [email protected] start: `concurrent "npm run tsc:w" "npm run lite" ` 9 verbose stack Exit status 127 9 verbose stack at EventEmitter.<anonymous> (/usr/local/lib/node_modules/npm/lib/utils/lifecycle.js:213:16) 9 verbose stack at EventEmitter.emit (events.js:110:17) 9 verbose stack at ChildProcess.<anonymous> (/usr/local/lib/node_modules/npm/lib/utils/spawn.js:14:12) 9 verbose stack at ChildProcess.emit (events.js:110:17) 9 verbose stack at maybeClose (child_process.js:1015:16) 9 verbose stack at Process.ChildProcess._handle.onexit (child_process.js:1087:5) 10 verbose pkgid [email protected] 11 verbose cwd /Users/tmrovsky/Documents/angular2/angular2-quickstart 12 error Darwin 13.4.0 13 error argv "node" "/usr/local/bin/npm" "start" 14 error node v0.12.2 15 error npm v2.7.4 16 error code ELIFECYCLE 17 error [email protected] start: `concurrent "npm run tsc:w" "npm run lite" ` 17 error Exit status 127 18 error Failed at the [email protected] start script 'concurrent "npm run tsc:w" "npm run lite" '. 18 error This is most likely a problem with the angular2-quickstart package, 18 error not with npm itself. 18 error Tell the author that this fails on your system: 18 error concurrent "npm run tsc:w" "npm run lite" 18 error You can get their info via: 18 error npm owner ls angular2-quickstart 18 error There is likely additional logging output above. 19 verbose exit [ 1, true ] I had: typescript 1.7.5 version node 0.12.2 version
Maybe someone could help solve the problem :) ?

To solve the Missing script: "start" error, make sure to add a start command to the scripts object in your package. json file and open your shell or IDE in the root directory of your project before running the npm start command.
npm start is the short form for npm run start . So, its one and the same thing. Show activity on this post.
Change the start field in package.json from
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" " to
"start": "concurrently \"npm run tsc:w\" \"npm run lite\" " If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
