problem when running npm run watch

[FyllipeDavid]

You first need to do an npm install cross-env,
then in package.json change the following lines:
"watch": "cross-env NODE_ENV=development webpack --watch --config ./webpack/webpack.config.js",
"production": "cross-env NODE_ENV=production webpack --config ./webpack/webpack.config.js --display-entrypoints",

Thank you so much for this! But I can't find out how to make it build! It gives me errors!

[FyllipeDavid]

My English is not very good. As I understand it you want to know how to fix it? If so, I'll tell you how I did it.
1° npm install cross-env;
2° Add in package.json in watch and production:
watch": "cross-env NODE_ENV=development webpack --watch --config ./webpack/webpack.config.js",
"production": "cross-env NODE_ENV=production webpack --config ./webpack/webpack.config.js --display-entrypoints",

No not that sorry. What I have an issue with is npm run build. I cannot build it and update it to WordPress. When I try updating the files with my own changes, what happens is that the WordPress template won't show up anymore, it'll be blank. When I go to build it it says that the build script is missing. I tried making my own build script but to no avail. This repo is very important to a startup operation I'm in charge of. And this template is perfect for what I have in mind for my team of developers. So finding a fix is important to me. Thank you. I'm sorry about your poor English.

Your script will work after adding npm install cross-env, and then adding cross-env before NODE_ENV, as I put in the example above.
watch": "cross-env NODE_ENV=development webpack --watch --config ./webpack/webpack.config.js",
"production": "cross-env NODE_ENV=production webpack --config ./webpack/webpack.config.js --display-entrypoints",
The main one is npm install cross-env

[elsan32bit]

Yes. I'm saying that I did all of that. Added "production" and "watch" and did npm install cross-env. It still cannot build. I can successfully do npm run watch afterward but not npm run build.

Working good

Hi there. I cannot get it to work. I followed a bunch of tips&tricks, but to no avail. Maybe you guys can help me?

Hello, install cross-env and changed my package.json as follow:

  "scripts": {
    "watch": "cross-env NODE_ENV=development webpack --watch --config ./webpack/webpack.config.js",
    "production": "cross-env NODE_ENV=production webpack --config ./webpack/webpack.config.js --display-entrypoints",
    "rmdist": "rimraf dist"
  },

Getting:

TypeError: object null is not iterable (cannot read property Symbol(Symbol.iterator))

Any idea?

Hi the answer was posted in another thread, here you go.

Working if i replace in webpack/loaders/files:

const [, themeName] = __dirname.match(/\/wp-content\/themes\/([^/]+)\/webpack\/loaders$/)

with

const themeName = __dirname.match(/\/wp-content\/themes\/([^/]+)\/webpack\/loaders$/)

Babel loader uses babel core 7, make sure to update it, you can use: npm install @babel/core @babel/preset-env
