Not showing the real missing module
here I miss-spelled postcss-loader to postcss-loadedr, and use it with stylus-loader to import some .styl file, can we have the error log showing the real missing module inseatd of b.styl?
I encountered the same issue with sass-loader, it's rather frustrating when being pointed in the wrong direction regarding errors
Could you provide a repro, or even better contribute a test via a PR? Thats would help me a great deal to fix this issue!
Well, I am using the vue webpack template, here are the steps I found to reproduce the issue:
- install the template (
vue init webpack friendly-errors-demo) (just follow the wizard to complete) - open the file
src/components/Hello.vueand change the style tag from this
<style scoped>
...
</style>
to this
<style scoped lang="scss">
...
</style>
which should trigger something like this:

A slightly more advanced reproduction, but with a clearer demonstration of the error would be if you create a separate scss file and attempt to import that, which results in something like below:

as you can see, on the left the plugin tells me that there's a problem with the import of ./style.scss while the browser clearly shows that it's sass-loader not being found causing the problem.
Hope that helps, if you need more info let me know
Any progress on this?
Just encountered this, from my debugging:
function isModuleNotFoundError (e) {
const webpackError = e.webpackError || {};
return webpackError.dependencies
&& webpackError.dependencies.length > 0
&& e.name === 'ModuleNotFoundError'
&& e.message.indexOf('Module not found') === 0;
}
it's not e.name === 'ModuleNotFoundError' it's webpackError.name === 'ModuleNotFoundError'.
Though it gets glued up at the top with other output, while the details are at the very bottom.
