Using node 6.9.1

        "underscore": "^1.8.3",
        "winston": "^2.3.1"
      }
    }

Is it because of the node modules which i have used?

Or is it the problem during the loading of modules?

Answer 1

It seems that your package.json is not a valid JSON.

Update:

Kudu uses the following code to read the package.json file, see line 179 of selectNodeVersion.js.

json = existsSync(packageJson) && JSON.parse(fs.readFileSync(packageJson, 'utf8'));

So, before you push the package.json to github, you can use the code below to verify the file on your local:

var fs = require("fs");
var json = JSON.parse(fs.readFileSync("./package.json", 'utf8'));
console.log(json);

For example, I added one more } at line 38 in package.json your provided above, I would get the same error as yours:

Or you can just use the command npm install to check it:
