2.0.0 Error: Path must be a string. Received undefined

[sarendipitee]

I consistently receive this error in every project that I've upgraded to 2.0.0:

ERROR in ./~/css-loader!./~/stylus-loader!src/styles.styl

Doesn't matter what file. Happens on first stylus file it tries to load and aborts.

Webpack.config.js:

module: {
        loaders: [
            {test: /\.styl$/, loader: 'style-loader!css-loader!stylus-loader'},
        ]
}

Turning source maps off is a work around, it's waiting on #104 to be merged...

Did you guys die? @mzgoddard @shama

@nfour Sometimes I wonder that myself.

I'm getting this for new node versions:

   189| @import './print/print'
   190|
   191| /* Components */
   192| @import './components/**/*'
   193|

Doesn't happen for node v5.1.0, but for 6.2.0+

any ideas guys?

my solution :

npm install webpack@v1.14.0 --save-dev
npm install stylus@v0.54.5 --save-dev
npm install stylus-loader@v2.4.0 --save-dev

(node v7.2.0)

it works 😀

Thank you LinZap! We have a team of 5 devs and our projects stalled while onboarding new members because they had a newer version of node than the rest of us (since they had just recently set up their dev environment, and our environments are nearly 2 years old now). Anyway, your solution got us back up and running. Thanks!!!
