《配置巴别塔》-《预置》-《Webpack》中的阶段0
提问于 2017-06-26 16:54:30
我尝试在我的webpack.config.js中添加babel-preset-stage 0，下面是我的配置代码：
module.exports = {
entry: './app/app.jsx',
output: {
path: __dirname,
filename: './public/bundle.js'
},
resolve: {
root: __dirname,
alias: {
},
extensions: ['', '.js', '.jsx']
},
module: {
loaders: [
{
loader: 'babel-loader',
query: {
presets: ['stage-0', 'react', 'es2015']
},
test: /\.jsx?$/,
exclude: /(node_modules|bower_components)/
}
]
}
};
然而，我最终得到了这个错误：
ERROR in ./app/app.jsx
Module build failed: TypeError: Path must be a string. Received undefined

当我删除预设中的“阶段0”时，它工作得非常好。以下是我的dev依赖项：
"devDependencies": {
"babel-core": "^6.5.1",
"babel-loader": "^6.2.2",
"babel-preset-es2015": "^6.5.0",
"babel-preset-react": "^6.5.0",
"babel-preset-stage-0": "^6.24.1",
"webpack": "^1.12.13"
}

建议在项目的根目录中添加.babelrc，然后：
{
"presets": [
"es2015",
"stage-0",
"react"
]
