Babel Errors in Webpack Configs after Updating Webpack - javascript

I am trying to update Webpack to a newer versions (by removing node_modules then running yarn), but I am not able to solve all the config errors shown below.
So far in the Webpack config, I have changed query to options, and loaders to rules. In package.json, I have replaced --colors with --color.
Original webpack.config.js [Source]:
const path = require('path')
const webpack = require('webpack')
const CopyWebpackPlugin = require('copy-webpack-plugin')
module.exports = {
entry: {
background: path.join(__dirname, './src/background'),
entry: path.join(__dirname, './src/entry'),
},
output: {
path: path.join(__dirname, './dist'),
filename: '[name].js',
},
plugins: [
new CopyWebpackPlugin([
{ from: 'src/manifest.json' },
{ from: 'images/**/*' }
]),
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: JSON.stringify('production')
}
})
],
resolve: {
extensions: ['.js']
},
module: {
loaders: [{
test: /\.js$/,
loader: 'babel-loader',
query: {
presets: ['react', 'es2015', 'stage-0']
},
exclude: /node_modules/
}]
}
}
Current webpack.config.js:
const path = require("path");
const webpack = require("webpack");
const CopyWebpackPlugin = require("copy-webpack-plugin");
module.exports = {
entry: {
background: path.join(__dirname, "./src/background"),
entry: path.join(__dirname, "./src/entry"),
},
output: {
path: path.join(__dirname, "./dist"),
filename: "[name].js",
},
plugins: [
new CopyWebpackPlugin([
{ from: "src/manifest.json" },
{ from: "images/**/*" },
]),
new webpack.DefinePlugin({
"process.env": {
NODE_ENV: JSON.stringify("production"),
},
}),
],
resolve: {
extensions: [".js"],
},
module: {
rules: [
{
test: /\.js$/,
loader: "babel-loader",
options: {
presets: ["react", "es2015", "stage-0"],
},
exclude: /node_modules/,
},
],
},
};
Still many of the following errors...
ERROR in ./src/background.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):
TypeError: Cannot read property 'babel' of undefined
at Object.module.exports (/home/gameveloster/sidebar/node_modules/babel-loader/lib/index.js:103:36)
but there's no babel in the files stated in the errors, like ./src/background.js.
What is the correct way to fix this issue? Thanks!

the error gives the npm name of a package that does not exist

An error appeared - Cannot find the module, but the problem is that such a module does not exist. The correct module name is babel-plugin-proposal-class-properties (and the error - 'babel-plugin-transform-class-propties'). Please tell me what could be the problem.
I type "npm run start:dev" into the terminal and I get the error output.

Webpack does not recognize ractive-loader

I have a project using ractivejs with webpack. I added the ractive-loader, which can be found here https://www.npmjs.com/package/ractive-loader
When I try to build the project using npm run build:dev, i get the following error message in template:
`ERROR in ./src/Templates/Feed/Main.html 1:2
Module parse failed: Unexpected character '#' (1:2)
You may need an appropriate loader to handle this file type.
> {{#Feeds}}
| {{title}}
| {{/Feeds}}`
Template: Main.html
`{{#Feeds}}
<h1>{{title}}</h1>
{{/Feeds}}`
My webpack looks like this:

from looking at the docs here
https://github.com/rstacruz/ractive-loader
the syntax for adding ractive-loader is just 'ractive' instead of 'ractive-loader'
use: {
test: /\.html$/,
loader: 'ractive'
}
altho it seems they do it a bit differently if you follow their example exactly
module: {
loaders: [
{ test: /\.html$/, loader: 'ractive' }
]
}

webpack4 css bundling not working for custom style names

I'm working on a making my own boilerplate for React using Webpack4 and have run the issue of my css file being bundled and not rendering specific custom styles. As you can see I am using the sass-loader compile all my .sass/scss files together and postcss-loader to autoprefixing, css-loader to load the compiled css files, MiniCssExtractPlugin.loader extracts CSS into separate files, and finally style-loader to inject my css. It does all this correctly buy doesn't seem to actually apply the styles. Could anybody explain why this occurs?

Move react and react-dom to dependencies instead of devDependecies in your package.json then try to build again.
Check this answer for an explanation:
Bower and devDependencies vs dependencies
Your react and react-dom packages are dependencies try moving them there.
Try modifying your webpack config file to some like this:
module.exports = {
entry: [
'./app/app.js',
],
output: {
path: path.resolve(__dirname, 'dist'),
