【问题描述】:
我已经阅读了有关类似问题的多个主题并尝试了一些建议,但没有结果。
我学习了一些与 React.js 和 WebPack 3 相关的教程。结果,除了 IE 10 及以下版本之外,该应用程序在所有浏览器(目前)上都运行良好。错误指向 bundle.js(一旦我使用配置 Nr.1):SCRIPT1002: Syntax error 和行 - const url = __webpack_require__(83);
使用配置 Nr2.,在本地服务器上 - : SCRIPT1002: Syntax error - 与 eval() 一致
同样的配置,但在远程服务器上运行会产生一些不同的错误:
SCRIPT5009: 'Set' is undefine
WebPack 配置 Nr1.:
const HtmlWebpackPlugin = require('html-webpack-plugin');
const HtmlWebpackPluginConfig = new HtmlWebpackPlugin({
template: './index.html',
filename: 'index.html',
inject: 'body'
})
module.exports = {
entry: './index.js',
output: {
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /\.json$/,
exclude: /node_modules/,
loader: 'json-loader'
},
{
test: /\.css$/,
loader: "style-loader!css-loader"
}
],
rules: [
{
test: /\.js$/,
exclude: /(node_modules)/,
use: {
loader: 'babel-loader',
options: {
presets: ['env', 'react']
}
}
}
]
},
devServer: {
historyApiFallback: true,
contentBase: './'
},
plugins: [HtmlWebpackPluginConfig]
}
WebPack 配置 Nr2.:
const path = require('path');
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const PreloadWebpackPlugin = require('preload-webpack-plugin');
const ScriptExtHtmlWebpackPlugin = require('script-ext-html-webpack-plugin');
const StyleExtHtmlWebpackPlugin = require('style-ext-html-webpack-plugin');
const CompressionPlugin = require('compression-webpack-plugin');
const autoprefixer = require('autoprefixer');
const staticSourcePath = path.join(__dirname, 'static');
const sourcePath = path.join(__dirname);
const buildPath = path.join(__dirname, 'dist');
module.exports = {
stats: {
warnings: false
},
devtool: 'cheap-eval-source-map',
devServer: {
historyApiFallback: true,
contentBase: './'
},
entry: {
app: path.resolve(sourcePath, 'index.js')
},
output: {
path: path.join(__dirname, 'dist'),
filename: '[name].[chunkhash].js',
publicPath: '/'
},
resolve: {
extensions: ['.webpack-loader.js', '.web-loader.js', '.loader.js', '.js', '.jsx'],
modules: [
sourcePath,
path.resolve(__dirname, 'node_modules')
]
},
plugins: [
new webpack.DefinePlugin({
'process.env.NODE_ENV': JSON.stringify('production')
}),
new webpack.optimize.ModuleConcatenationPlugin(),
new webpack.optimize.CommonsChunkPlugin({
name: 'vendor',
filename: 'vendor.[chunkhash].js',
minChunks: Infinity
}),
new webpack.LoaderOptionsPlugin({
options: {
postcss: [
autoprefixer({
browsers: [
'last 3 version',
'ie >= 10'
]
})
],
context: staticSourcePath
}
}),
new webpack.HashedModuleIdsPlugin(),
new HtmlWebpackPlugin({
template: path.join(__dirname, 'index.html'),
path: buildPath,
excludeChunks: ['base'],
filename: 'index.html',
minify: {
collapseWhitespace: true,
collapseInlineTagWhitespace: true,
removeComments: true,
removeRedundantAttributes: true
}
}),
new PreloadWebpackPlugin({
rel: 'preload',
as: 'script',
include: 'all',
fileBlacklist: [/\.(css|map)$/, /base?.+/]
}),
new webpack.NoEmitOnErrorsPlugin(),
new CompressionPlugin({
asset: '[path].gz[query]',
algorithm: 'gzip',
test: /\.js$|\.css$|\.html$|\.eot?.+$|\.ttf?.+$|\.woff?.+$|\.svg?.+$/,
threshold: 10240,
minRatio: 0.8
})
],
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: ['env', 'react', 'es2015'],
plugins: ["transform-es2015-arrow-functions"]
}
},
include: sourcePath
},
{
test: /\.css$/,
exclude: /node_modules/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: [
{ loader: 'css-loader', options: { minimize: true } },
'postcss-loader',
'sass-loader'
]
})
},
{
test: /\.(eot?.+|svg?.+|ttf?.+|otf?.+|woff?.+|woff2?.+)$/,
use: 'file-loader?name=assets/[name]-[hash].[ext]'
},
{
test: /\.(png|gif|jpg|svg)$/,
use: [
'url-loader?limit=20480&name=assets/[name]-[hash].[ext]'
],
include: staticSourcePath
}
]
}
};
这里我还添加了 es2015 到预设中:['env', 'react', 'es2015'] 和 plugins: ["transform-es2015-arrow-functions"] 但没有任何意义。
如果 babel 加载器由于配置错误或其他原因根本无法工作,我认为整个应用程序将无法启动。我认为应该对预设或它们的顺序做一些事情......需要经验丰富的开发人员的建议
更新
我已将 devtool 更改为 inline-cheap-module-source-map 并将错误点指向 overlay.js -> const ansiHTML = require('ansi-html');
【问题讨论】:
-
我已经成功使用UglifyJS 和
--ie8选项使您的代码具有ie-proof。 -
hm.. 我已将
new webpack.optimize.UglifyJsPlugin({ compress: { warnings: false, screw_ie8: true, conditionals: true, unused: true, comparisons: true, sequences: true, dead_code: true, evaluate: true, if_return: true, join_vars: true },output: { comments: false} }),添加到配置中。现在错误指向(module,exports,__webpack_require__)。我在本地运行这个测试 -npm start -
你能把你的 package.json 添加到问题中吗?
