windows 8 :The syntax of the command is incorrect. npm ERR! code ELIFECYCLE

I had tough time setting up this simpe solution on windows ,seems like it is very outdated

bundle.js 3.11 kB 0 [emitted] main [0] ./src/app/index.js 40 bytes {0} [built] The syntax of the command is incorrect. npm ERR! code ELIFECYCLE

output :

bundle.js 3.11 kB 0 [emitted] main [0] ./src/app/index.js 40 bytes {0} [built] The syntax of the command is incorrect. npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! reactbasic1@1.0.0 build: webpack -d && copy src/index.html dist/index.html && webpack-dev-server --content-base sr c/ --inline --hot npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the reactbasic1@1.0.0 build script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Not sure if it is very outdated . Dev dependencies: “devDependencies”: { “babel-core”: “^6.25.0”, “babel-loader”: “^7.1.1”, “babel-preset-es2015”: “^6.24.1”, “babel-preset-react”: “^6.24.1”, “babel-preset-stage-2”: “^6.24.1”, “webpack”: “^3.0.0”, “webpack-dev-server”: “^2.5.0” }

I changed as below, in package.json After change :

  "scripts": {
    "start": "npm run build",
    "build": "webpack -d && copy src\\index.html dist\\index.html /Y && webpack-dev-server --content-base src/ --inline --hot", 
    "build:prod": "webpack -p && copy src\\index.html dist\\index.html"
  },

Before change :

"scripts": {
"start": "npm run build",
"build": "webpack -d && copy src/index.html dist/index.html && webpack-dev-server --content-base src/ --inline --hot",
"build:prod": "webpack -p && cp src/index.html dist/index.html"
},
