我在运行我的Webpack3和Angular4 AoT时遇到错误(仅在AoT中发生)。我收到的错误是ERROR in Expected 'styles' to be an array of strings.
。我已经尝试过这里提出的其他几种方法https://github.com/webpack-contrib/style-loader/issues/123,但没有运气。
以下是我的webpack配置:
const webpack = require('webpack');
const autoprefixer = require('autoprefixer');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const { ENV, IS_PRODUCTION, APP_VERSION, IS_DEV, dir, DEPS, IN_MEM_DB } = require('./helpers');
const { CheckerPlugin } = require('awesome-typescript-loader');
const AotPlugin = require('@ngtools/webpack').AotPlugin;
module.exports = function(options = {}) {
return {
context: dir(),
resolve: {
extensions: ['.ts', '.js', '.json', '.css', '.scss', '.html'],
modules: [
'node_modules',
dir('src')
]
},
performance: {
hints: false
},
output: {
path: dir('dist'),
filename: '[name].js',
sourceMapFilename: '[name].map',
chunkFilename: '[id].chunk.js'
},
module: {
exprContextCritical: false,
rules: [
{
test: /\.html$/,
loader: 'raw-loader'
},
{
test: /\.json/,
loader: 'json-loader'
},
{
test: /\.(png|woff|woff2|eot|ttf|svg|jpeg|jpg|gif)$/,
loader: 'url-loader',
query: {

}
},
{
test: /\.css/,
use: ['to-string-loader', 'css-loader' ,'postcss-loader?sourceMap']
},
{
test: /\.scss$/,
use: ['to-string-loader', 'css-loader', 'postcss-loader?sourceMap', 'sass-loader?sourceMap']
},
]
},
plugins: [
new AotPlugin({
tsConfigPath: './tsconfig.json',
entryModule: 'src/app/app.module#AppModule'
}),
new CopyWebpackPlugin([
{
from: 'src/assets',
to: 'assets'
},
{
from: 'node_modules/twemoji/2/svg',
to: 'assets/svgs'
}
]),
new webpack.NamedModulesPlugin(),
new webpack.DefinePlugin({
ENV,
IS_PRODUCTION,
DEPS,
APP_VERSION,
HMR: options.HMR,
IS_DEV,
IN_MEM_DB
}),
new CheckerPlugin(),
new webpack.LoaderOptionsPlugin({
options: {
context: dir(),
tslint: {
emitErrors: false,
failOnHint: false,
resourcePath: 'src'
},
postcss: function() {
return [ autoprefixer ];
},
sassLoader: {
includePaths: [
dir('node_modules', '@swimlane', 'ngx-ui', 'release'),
dir('node_modules', '@swimlane', 'ngx-ui', 'release', 'styles')
]
}
}
})
]
};
};

除了上述方法之外,我还尝试过Extract Text Webpack插件,但也没有运气。这是我尝试使用ETWP 3.0.0-beta3的配置
{
test: /\.css/,
use: ExtractTextPlugin.extract({
fallback: "style-loader",
use: ['to-string-loader', 'css-loader' ,'postcss-loader?sourceMap']
})
},
{
test: /\.scss$/,
exclude: /\.component.scss$/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: ['css-loader', 'postcss-loader?sourceMap', 'sass-loader?sourceMap']
})
},
{
test: /\.component.scss$/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: ['to-string-loader', 'css-loader', 'postcss-loader?sourceMap', 'sass-loader?sourceMap']
})
}

我很好奇是否有人看到我可能正在做的任何事情,而其他案件可能没有。
此外,是否有人知道如何调试可能导致此问题的文件?我无法从我收到的错误中找到任何有用的错误。
