css-loader doesn't work anymore with v0.15.1

[gitawego]

after updated to v0.15.1 from v0.14.x, css loader doesn't work any more.

here is the config:

const sassLoaders = [
  "css",
  "sass?" + ["outputStyle=expanded",
    "includePaths[]=" + nodeModulesPath,
    "includePaths[]=" + bowerComponentsPath].join("&")
].join("!");

later on

{
        test: /\.scss$/,
        loader: ExtractTextPlugin.extract("style-loader", sassLoaders, {
          publicPath: './'
        })

      },

I've noticed in file /node_modules/css-loader/lib/processCss.js, wether I use sourcemap or not, the variable inputMap is always string null.. and it crashes postcss.

var result = pipeline.process(inputSource, {
        from: options.from,
        to: options.to,
        map: {
            prev: inputMap,
            sourcesContent: true,
            inline: false,
            annotation: false
        }
    });

so the final way I do for now is modify file /node_modules/css-loader/lib/loader.js, at line 17, detect if map is not null before stringify it

if(map && typeof map !== "string") {
        map = JSON.stringify(map);
    }

with this hack, it works without map....

Confirmed.

The solution above works for me as well.

Thanks! Your fix works for me

[harrisrobin]

Confirmed. I simply downgraded to 0.14x instead of modifying library code.

[phatshambler]

Same here, fix works.

[dreampulse]

I have the same problem..

[mmahalwy]

same here. I get it from extract-text-plugin which requires any latest version.

0.14x works for me. Been debugging this all day.. : - (

[pthorn]

Same here. Reverted to 0.14.5.
