webpack (with sass-loader) - scss file @import doe

问题:

My project structure:

webpack.config.js
app--

   --> src
   ---->> components
   ------>>> myComponent.js
   ------>>> myComponent.scss

   --> styles
   ---->> variables.scss

In webpack.config module.exports:

...
resolve: {
    alias: {
       styles: path.join(__dirname, 'app/styles') 
   }
}

In my file - myComponent.scss:

@import "styles/variables";

I am getting this error when building bundle.js:

Module build failed:
@import "styles/variables";
^
      File to import not found or unreadable: styles/variables

How can I @import aliases in sass files?

回答1:

I was able to use, on a stylesheet, an alias that I defined in webpack by using the following:

@import '~alias/variables';

just by prefixing the alias with ~ did the trick for me, as suggested by documentation in here

回答2:

Another fix related to this subject, remove .scss

@import '~scss/common.scss';

should be

@import '~scss/common';

回答3:

Since your webpack.config.js file is already in the /app folder, shouldn’t the alias be:

resolve: {
   alias: {
       styles: path.join(__dirname, 'styles') 
   }
}

?

回答4:

In my case the dependency is a node module, therefore I can import it like this:

@import '~node-module-name/variables';

And when using the actual node module dir name, my editor (PhpStorm) is not showing unresolved path error anymore (the problem which @tkiethanom mentioned). It looks like I need to specify alias in webpack config if I want to use sass style imports (e.g. my-package/colors instead of my-package/_colors.scss), and it seems it doesn't matter what is the name of that alias, as long as I use node module directory name
