“You may need an appropriate loader to handle this file type” with Webpack and CSS - css

Question

I an new to webpack, and I have been able to get it to packup my javascript, but the CSS eludes me. I keep getting a:
“You may need an appropriate loader to handle this file type”
One the first line of my css file. The CSS file is simple:
body {
color:red
}
The webpack.config.js looks like this:
module.exports = {
debug: true,
entry: [ './sdocs.js' ],
output: {
filename: './[name].bundle.js'
},
loaders: [
{ test: /\.css$/, loader: "style-loader!css-loader" },
],
}
sdocs.js is also simple and looks like this:
require('./sdocs.css');
Finally the result of running webpack look like this:
ERROR in ./sdocs.css
Module parse failed: C:\Users\Tim\PhpstormProjects\xxx\sdocs.css
Unexpected token (1:5)
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected token (1:5)

I have triple checked, css-loader and style-loader are loaded at the local level. I had them installed globally at first, but i removed them globally and reinstalled them locally. BTW, the debug flag did nothing extra, no change in output, which i thought was weird.
I am running on a windows platform is that matters

Answer 1

Ok,
This is what fixed it for me if anyone runs across this. The issue was in the webpack.config.js. The one the finally worked looked like this:
module.exports = {
debug: true,
entry: [ './sdocs.js' ],
output: {
filename: './[name].bundle.js'
},
module: {
loaders: [
{ test: /\.css$/, loader: "style-loader!css-loader" },
],
}
}
The piece that was missing was moving the loaders key under a modules key.

Answer 2

I tried specifying 'loaders' in 'module' key. But, it didn't work for me. I think for webpack versions above 2.5.1, adding a rule in 'module' works perfectly.
Add this in your webpack.config.js
module: {
rules:[
{ test: /\.css$/, use: [ 'style-loader', 'css-loader' ] }
]
}
When you add it as a rule you wouldn't have to provide tha loaders key separately!

Answer 3

I was facing this problem for about 10 days. so here's the solution i found to fix this problem. After using create-react-app you created a react app, first run the script npm run eject.
Then, go to the following link https://webpack.js.org/loaders/, click on the val-loader and install it as described there, then install the url-loader file.
It has to work now.

Answer 4

I had met the same issue you meet. Maybe you were in dev environment (hot reload), just press ctrl+c to kill the process on terminal, and reopen dev env (npm run dev).
