我试图通过Webpack ProvidePlugin全局使用下划线,但是它没有识别下划线,并且在控制台中我收到以下错误。
VM43994:1 Uncaught ReferenceError: _ is not defined(…)
我在index.js中导入下划线(现在我可能不需要供应商捆绑?),我的webpack配置如下所示。在一个阶段,我认为我有它工作(在做供应商捆绑之前),但我现在认为我可能是错的,因为我觉得我已经尝试过我尝试过的所有途径。任何帮助将不胜感激。
const webpack = require('webpack');
const path = require('path');
const precss = require('precss');
const autoprefixer = require('autoprefixer');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const postcssImport = require('postcss-import');
module.exports = {
context: __dirname + '/frontend',
devtool: 'source-map',
entry: {
app: './index.js',
vendor: ['underscore'],
},
output: {
filename: 'bundle.js',
path: path.join(__dirname, './static'),
},
module: {
loaders: [
{ test: /\.js$/, loader: 'babel', exclude: /node_modules/, query: { presets: ['es2015'] } },
{ test: /\.css$/, loader: ExtractTextPlugin.extract('style', 'css?sourceMap&importLoaders=1!postcss') },
],
},
plugins: [
new ExtractTextPlugin('si-styles.css'),
new webpack.ProvidePlugin({ underscore: 'underscore' }),
new webpack.optimize.CommonsChunkPlugin(/* chunkName= */'vendor', /* filename= */'vendor.bundle.js', Infinity),
],
postcss: function(webpack) {
return [
postcssImport({ addDependencyTo: webpack }), // Must be first item in list
precss,
autoprefixer({ browsers: ['last 2 versions'] }),
];
},
};

多一点调查和this seems to work
{
plugins: [
new webpack.ProvidePlugin({
_: 'underscore'
})
]
}
同样在您的TS文件中,您可以添加window['_'] = require('underscore')
