Cannot read property 'length' of undefined #36
Description
Hello,
My project uses webpack@3.10.0 and I am seeing the below error when I run webpack -p command to build my project.
ERROR in ./node_modules/css-loader!./node_modules/sass-loader/lib/loader.js!./stylesheets/main.scss
Module build failed: TypeError: Cannot read property 'length' of undefined
at module.exports (..\node_modules\postcss-value-parser\lib\unit.js:7:23)
at ..\node_modules\css-loader\node_modules\postcss-minify-gradients\dist\index.js:65:65
at Array.forEach (native)
at ..\node_modules\css-loader\node_modules\postcss-minify-gradients\dist\index.js:60:22
Here is my webpack.config.js:
module: [
{
test: /\.scss$/,
include: APP_DIR,
loaders: ['style-loader', 'css-loader', 'sass-loader'],
},
I have a potential fix in place in unit.js which removes the above error:
module.exports = function (value) {
var pos = 0;
var length = Object.prototype.toString(value) === '[object Array]'
? value.length
: 0;
...
}
Do you think this is a valid fix? If yes, I can send a PR for this..
Thanks..

@sacredMonster I had this issue because i was doing
@importinside my css files. You should import your global css files insideindex.js. For some reason the new version of css-loader fromreact-scripts4.0.3did not like this
