Module not found: Error: Cannot resolve 'file' or 'directory' (import sass in webpack)

Question

My project structure is:

/src/styles/main.scss

@import 'materialize/sass/materialize.scss';

....

I also try @import './materialize/sass/materialize.scss'; here notwork.

It only work when I import the lib in index.js

/src/index.js (this worked)

import './styles/reset.css';
import './styles/main.scss';
import './styles/font-awesome/font-awesome.scss';

webpack loader:

loaders: [
  {
    test: /\.js?/,
    exclude: [/node_modules/, /styles/],
    loaders: ['babel'],
    include: path.join(__dirname, 'src')
  },
  {
    test: /\.scss$/,
    loader: 'style!css!sass'
  },
  {
    test: /\.css$/,
    loader: "style-loader!css-loader"
  },
  {
    test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/,
    loader: 'url-loader?limit=10000&mimetype=application/font-woff'
  },
  {
    test: /\.(ttf|eot|svg)(\?v=[0-9]\.[0-9]\.[0-9])?$/,
    loader: 'file-loader'
  }

]

But got error:

It looks like webpack search for a wrong directory, not search fonts folder under materialize.

I got error every time when I put import sass lib in main.scss, which force me to put import to index.js. Anyway to workaround ?

Update:

I found there are config in \src\styles\materialize\sass\components\_variables.scss:

$roboto-font-path: "../fonts/roboto/" !default;

But it is relate to components, is this webpack 's bug?

I think it is a problem related to css-loader or sass-loader, somehow they are not really resolving the paths correctly when inside node_modules. And that is the reason why you have those errors.

Look at the error:

Error: Cannot resolve 'file' or 'directory' ../fonts/roboto/Roboto-Bold.woff in E:\Project\simple-redux-boilerplate\src\styles

It seems that the css-loader is trying to find ../fonts/ inside your src/styles folder.

As a workaround, you can specify the "correct" place where the fonts are placed as your $roboto-font-path variable. If installed via npm install materialize-css you can do the following:

$roboto-font-path: '~materialize-css/fonts/roboto/';

The tilde (~) character will say to your loaders to look into node_modules. Then, when resolving your paths, your loaders will look to the correct place and there will be no errors.

I think (and tested it locally) you don't need to use the tilde character to look at node_modulesusing sass-loader.

If you don't want to look into node_modules (because you prefer to download the dependencies manually) you can just use the relative paths. In your case $roboto-font-path: './materialize/fonts/roboto/'; should fix it.

Update:

You can also try using resolve-url-loader, that tries to fix the urls for you.
