我在使用 babel-loader 时遇到了一些问题,并且无法终生找出问题所在。看起来 babel-loader 根本没有在编译,我怀疑 babel-loader 甚至没有被使用。即使我删除了use:
块中的所有内容,结果也是一样的。将debug: true
标志添加到选项不会更改控制台中的输出。但是,排除/包含选项确实有效,因此我确信正在使用该配置。有谁知道可能是什么问题?
var path = require('path');
module.exports = {
mode: 'development',
entry: './project/src/rovbasekart.js',
output: {
filename: 'rovbase.js',
path: path.resolve(__dirname, './project/src/dist')
},
module: {
rules: [{
test: /\.js$/,
include: [path.resolve(__dirname, '/project/src/')],
exclude: [/node_modules/, './project/src/dist', './project/src/lib'], // ignore all files in the node_modules folder
use: {
loader: 'babel-loader',
options: {
presets: [['@babel/preset-env', { "targets": { "browsers": "ie 11"}}]],
babelrc: false
}
}
}]
},
devtool: 'inline-module-source-map',
resolve: {
extensions: ['.js'],
alias: {
Rovbase: path.resolve('./project/src/'),
Verktoylinje: path.resolve('./project/src/verktoylinje'),
Verktoy: path.resolve('./project/src/verktoylinje/Verktoy'),
Styles: path.resolve('./project/src/styles')
}
}
};
