Currently utilizing extract-text-webpack-plugin version 2.0.0-rc.3 with Webpack version 2.2.1 and encountering an error during the build process:
/node_modules/extract-text-webpack-plugin/index.js:259
var shouldExtract = !!(options.allChunks || chunk.isInitial());
^
TypeError: chunk.isInitial is not a function
Here is a snippet of my webpack.config.js:
'use strict';
const argv = require('yargs').argv;
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const webpack = require('webpack');
module.exports = (function () {
let config = {
entry : './' + process.env.npm_package_config_paths_source + '/main.js',
output : {
filename : 'main.js'
},
watch : !!argv.watch,
vue : {
loaders : {
js : 'babel-loader',
sass : ExtractTextPlugin.extract("css!sass?sourceMap")
}
},
module : {
rules : [
{
test : /\.js$/,
use : 'babel-loader',
exclude : '/node_modules/'
},
{
test : /\.vue$/,
use : 'vue-loader',
options : {
loaders : {
'scss' : 'vue-style-loader!css-loader!sass-loader',
'sass' : 'vue-style-loader!css-loader!sass-loader?indentedSyntax'
},
}
}
]
},
plugins : [
new webpack.DefinePlugin({
'process.env' : {
npm_package_config_paths_source : '"' + process.env.npm_package_config_paths_source + '"'
}
}),
new ExtractTextPlugin("style.css")
],
resolve : {
alias : {
'vue$' : 'vue/dist/vue.common.js'
}
},
babel : {
"presets" : ["es2015", "stage-2"],
"comments" : false,
"env" : {
"test" : {
"plugins" : ["istanbul"]
}
}
},
devtool : "#source-map"
};
if (process.env.NODE_ENV === 'production') {
config.plugins = [
new webpack.DefinePlugin({
'process.env' : {
NODE_ENV : '"production"',
npm_package_config_paths_source : '"' + process.env.npm_package_config_paths_source + '"'
}
}),
new webpack.optimize.UglifyJsPlugin(),
new ExtractTextPlugin("style.css")
];
config.devtool = "#source-map";
}
return config;
})();
Removing
new ExtractTextPlugin("style.css")plugins array allows the build to run without errors, but it does not generate the expected style.css file.
Upon adding the option allChunks: true, the error message changes to:
/node_modules/webpack/lib/Chunk.js:80
return this.entrypoints.length > 0;
^
TypeError: Cannot read property 'length' of undefined
