我試圖讓webpack解析一個使用新的異步/等待語法的javascript文件,但它一直給我一個解析錯誤。使用webpack解析異步函數的問題
這裏是我的webpack.config.js文件:
module.exports = {
entry: {
foo: './foo.js'
},
output: {
filename: 'webpack-compiled.js'
},
module: {
loaders: [
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
}
]
}
}
我的package.json文件:
{
"name": "async-func-test",
"version": "1.0.0",
"description": "",
"main": "foo.js",
"scripts": {
"buildWithBabel": "babel foo.js --out-file babel-compiled.js",
"buildWithWebpack": "webpack --progress --colors"
},
"author": "",
"license": "ISC",
"devDependencies": {
"babel-cli": "^6.18.0",
"babel-core": "^6.18.2",
"babel-loader": "^6.2.8",
"babel-plugin-syntax-async-functions": "^6.13.0",
"webpack": "^1.13.3"
}
}
我babel.rc文件:
{
"plugins": [
"syntax-async-functions"
]
}
而FOO .js文件:
async function asyncFunc() {
return 123
}
asyncFunc().then(x => console.log(x))
如果我運行npm腳本'buildWithBabel',它運行良好,沒有錯誤,並創建了正確輸出的babel-compiled.js。
但是,如果我跑故宮腳本「buildWithWebpack」,我得到了以下錯誤消息:
ERROR in ./foo.js Module parse failed: C:\Users\Redark\Desktop\asyncFuncTest\node_modules\babel-loader\lib\index.js!C:\Users\Redark\Desktop\asyncFuncTest\foo.js Unexpected token (1:6) You may need an appropriate loader to handle this file type. SyntaxError: Unexpected token (1:6)
我不需要改造異步功能,只是對其進行分析。我不知道爲什麼它不適用於webpack,因爲它應該使用.babelrc中的「syntax-async-functions」插件?
