Why not install dependencies?

I run the npm init --yes , then write the dependencies to the package.json file. That's what it is: `

 { "name": "webpack-tutorial", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", }, "devDependencies": { "babel-core": "^6.18.2", "babel-loader": "^6.2.7", "babel-plugin-transform-runtime": "^6.15.0", "babel-preset-es2015": "^6.18.0", "css-loader": "^0.25.0", "jade": "^1.11.0", "node-sass": "^3.12.5", "sass-loader": "^4.0.2", "vue": "*", "vue-html-loader": "^1.2.3", "vue-loader": "*", "vue-style-loader": "^1.0.0", "webpack": "*" }, "keywords": [], "author": "", "license": "ISC" }` 

After running the npm install command, and now some errors appear, what to do about it?
