最新バージョンのwebpackにアップグレードした後、次のエラーが表示されます。
WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema. - configuration has an unknown property 'postcss'. These properties are valid: object { amd?, bail?, cache?, context?, dependencies?, devServer?, devtool?, entry, externals?, loader?, module?, name?, node?, output?, plugins?, profile?, recordsInputPath?, recordsOutputPath?, recordsPath?, resolve?, resolveLoader?, stats?, target?, watch?, watchOptions? } For typos: please correct them. For loader options: webpack 2 no longer allows custom properties in configuration. Loaders should be updated to allow passing options via loader options in module.rules.
これがpostcssモジュールを示す私のwebpack設定です：
module: { loaders: [ // JavaScript / ES6 { test: /\.js$/, exclude: /node_modules/, loader: 'babel-loader' }, { test: /\.jsx?$/, include: path.resolve(__dirname, '../src/components'), exclude: /node_modules/, loader: 'babel-loader' }, // Sass { test: /\.scss$/, include: path.resolve(__dirname, '../src/sass'), exclude: /node_modules/, loader: 'style!css!postcss!sass' }, // CSS { test: /\.css$/, loader: 'style!css!postcss' }, // JSON { test: /\.json$/, exclude: /node_modules/, loader: 'json-loader' }, // Images // Inline base64 URLs for <=8k images, direct URLs for the rest { test: /\.(png|jpg|jpeg|gif|svg)$/, loader: 'url', include: [ path.resolve(__dirname, '../public'), path.resolve(__dirname, '../src/sass') ], exclude: /node_modules/, query: { limit: 8192, name: 'images/[name].[ext]?[hash]' } }, // Fonts { test: /\.(woff|woff2|ttf|eot)(\?v=\d+\.\d+\.\d+)?$/, loader: 'url', include: path.resolve(__dirname, '../src/sass'), exclude: /node_modules/, query: { limit: 8192, name: 'fonts/[name].[ext]?[hash]' } } ] }, postcss: function() { return [ autoprefixer({ browsers: ['last 2 versions'] }) ]; }
修正は、autoprefixerがファイルの先頭に含まれていることを確認し、postcssをプラグインセクションに移動することです。
const autoprefixer = require('autoprefixer');
plugins: [
// Shared code
new webpack.optimize.OccurrenceOrderPlugin(),
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor',
filename: 'vendor.bundle.js',
minChunks: Infinity
}),
new webpack.LoaderOptionsPlugin({
options: {
context: __dirname,
postcss: [
autoprefixer
]
}
})
]
