我遇到了一个我认为来自 webpack 的错误。这里是:
index.js:9 Uncaught ReferenceError: global is not defined
at eval (index.js:9)
at Object.<anonymous> (bundle.js:2548)
at __webpack_require__ (bundle.js:622)
at fn (bundle.js:48)
at eval (client:1)
at Object.<anonymous> (bundle.js:2541)
at __webpack_require__ (bundle.js:622)
at bundle.js:668
at bundle.js:671
我的 webpack 是:
import webpack from 'webpack';
import merge from 'webpack-merge';
import path from 'path';
import isDev from 'isdev';
import { Dir } from './src/utils';
const TARGET = process.env.npm_lifecycle_event;
let Config = {
entry: [
'babel-polyfill',
'react-hot-loader/patch',
path.join(Dir.src, 'client.js'),
],
output: {
path: path.join(Dir.public, 'build'),
filename: 'bundle.js',
},
target: 'node',
resolve: {
modules: [Dir.src, 'node_modules'],
extensions: ['*', '.js', '.jsx', '.json'],
},
module: {
rules: [
{
test: /\.js?$/,
enforce: 'pre',
loader: 'eslint-loader',
exclude: /node_modules/,
include: Dir.src,
},
{
test: /\.js?$/,
loader: 'babel-loader',
exclude: /node_modules/,
},
],
},
plugins: [
new webpack.optimize.OccurrenceOrderPlugin(),
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: JSON.stringify(process.env.NODE_ENV),
},
}),
],
};
if (TARGET === 'build:prod' && !isDev) {
Config = merge(Config, {
bail: true,
devtool: 'source-map',
output: { publicPath: '/build/' },
plugins: [
new webpack.optimize.DedupePlugin(),
new webpack.optimize.UglifyJsPlugin({
comments: false,
dropDebugger: true,
dropConsole: true,
compressor: {
warnings: false,
},
}),
],
});
}
if (TARGET === 'server:dev' && isDev) {
Config = merge(Config, {
devtool: 'eval',
entry: ['webpack-hot-middleware/client'],
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.NoEmitOnErrorsPlugin(),
],
});
}
const WebpackConfig = Config;
export default WebpackConfig;
这个错误只有在我添加了 Redux 建议的服务器端渲染后才开始出现。所以我在 ./src/utils/store.js 中使用带有window.__PRELOADED_STATE__的 store 水化,它也在index.ejs中,这是呈现给客户端的文件。
如果有的话,这也是我的 .babelrc:
{
"presets": ["es2015", "react", "stage-0"],
"env": {
"development": {
"plugins": ["react-hot-loader/babel"],
},
},
"plugins": [
"babel-root-import"
],
}
希望任何人都可以对此提供帮助-我在研究和试验中还没有找到解决方案。谢谢!
