Yarn 1.7 can't start webpack - node.js

Question

When trying to open webpack with yarn s I get the following error:
yarn s
yarn run v1.7.0
$ NODE_ENV=development webpack --config webpack.development.js
/bin/sh: webpack: command not found
error Command failed with exit code 127.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
I tried searching on google for the answer most promising seemed https://gist.github.com/DanHerbert/9520689 but still doesn't work. Anyone has any ideas?
This is my package.json:
cat package.json

When I run npm s I get:
npm s

I don't even know why it gets node 10.2.1 when i installed node6.
I have this in webpack.development.js:
cat webpack.development.js
const path = require('path');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const StatusPlugin = require('./front/utils/webpack-status-plugin');
const HappyPack = require('happypack');
const paths = {
src: path.join(__dirname, 'front'),
dest: path.join(__dirname, 'public', 'front'),
};
module.exports = {
context: paths.src,
devtool: 'eval',
entry: {
application: ['babel-polyfill', './application.js'],
admin: ['babel-polyfill', './admin.js'],
portal: ['babel-polyfill', './portal.js'],
},
externals: {
jquery: 'jQuery',

},
output: {

Answer 1

I think you forgot to run npm install

Answer 2

First of all, you'll need to run yarn command, to install the dependencies.
