我有三个文件webpack.config.base,webpack.config.dev,webpack.config.prod及相应的代码:
** webpack.config.base **
const webpack = require('webpack');
const path = require('path');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const parentDir = path.join(__dirname, '../');
module.exports = {
entry: [
path.join(parentDir, 'index.js'),
],
resolve: {
extensions: ['.js', '.jsx', '.json'],
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
loader: 'babel-loader',
},
{
test: /\.(png|jpg|jpeg|gif|svg|woff|woff2)$/,
use: [
{
loader: 'image-webpack-loader',
options: {
bypassOnDebug: true,
},
},
'url-loader?limit=10000',
],
},
{
test: /\.scss$/,
loader: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: ['css-loader', 'sass-loader'],
}),
},
],
},
output: {
path: `${parentDir}/dist`,
filename: 'bundle.js',
},
plugins: [
new ExtractTextPlugin({
filename: 'main.css',
}),
new webpack.DefinePlugin({
'process.env.NODE_ENV': JSON.stringify(process.env.NODE_ENV || 'development'),
}),
new webpack.optimize.OccurrenceOrderPlugin(),
new webpack.NoEmitOnErrorsPlugin(),
],
};
** webpack.config.dev **
const webpack = require('webpack');
const merge = require('webpack-merge');
const path = require('path');
const parentDir = path.join(__dirname, '../');
const config = require('./webpack.config.base.js');
module.exports = merge(config, {
devServer: {
inline: true,
colors: true,
progress: true,
hot: true,
open: true,
bail: true,
quiet: true,
contentBase: parentDir,
port: 7070,
historyApiFallback: true,
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
],
});
生产:
const webpack = require('webpack');
const config = require('./webpack.config.base.js');
config.plugins = config.plugins.concat([
new webpack.optimize.DedupePlugin(),
new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }),
new webpack.DefinePlugin({
'process.env.NODE_ENV': JSON.stringify('production'),
}),
]);
module.exports = config;
package.json中的脚本是
"dev": "./node_modules/.bin/webpack-dev-server --mode development --config ./webpack/webpack.config.dev.js",
使用npm run dev webpack dev服务器退出,状态代码为-1。任何人都可以告诉我哪里出错了?我正在使用的版本是:
"webpack": "^4.6.0",
"webpack-cli": "^2.1.2",
"webpack-dev-server": "^3.1.4"
提前致谢。我已经尝试在单个文件中使用它,它运行良好,但如果在三个不同的文件中这样划分,那么它会产生此错误。所有这些文件都在根目录下的webpack文件夹中。
答案 0 :(得分:0)
这三个选项产生了一个问题:
bail: true,
quiet: true,
colors: true
我删除了,现在工作正常。如果有人能够更新它为什么会如此,那么将有助于进一步理解。
