Question

during npm install on windows 10 i am getting this error I am using node v6.10.3 and npm v3.10.10

please help to correct this.

error I am getting

npm ERR! npm v3.10.10 npm ERR! file C:\angular2-helloworld\package.json npm ERR! code EJSONPARSE npm ERR! Failed to parse json npm ERR! Unexpected token '\r' at 5:71 npm ERR!

package.json file contents:

{ "name":"angular2-helloworld", "version":"1.0.0", "scripts":{ "start":"tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ", "tsc":"tsc", "tsc:w":"tsc -w", "lite":"lite-server", "typings":"typings", "postinstall":"typings install" }, "license":"ISC", "dependencies":{ "angular2":"2.0.0-beta.14", "systemjs":"0.19.25", "es6-shim":"^0.35.0", "reflect-metadata":"0.1.2", "rxjs":"5.0.0-beta.2", "zone.js":"0.6.6" }, "devDependencies":{ "concurrently":"^2.0.0", "lite-server":"^2.2.0", "typescript":"^1.8.9", "typings":"^0.7.12" } }

What tsc task do? Also why in your start script you start tsc without npm run but you start tsc:w as npm run tsc:w? — Sharikov Vladislav

\r means a carriage return. NPM is complaining about a carriage return at the very end of line 5. What text editor are you using to make changes to package.json? — Pop-A-Stash

You probably have an invisible character \r at line:

"start":"tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",

That character breaks the json parsing of the package.json file. Try to rewrite that part of the text by hand, or use a regex search to delete it in your text editor.
