我想去角度教程，并有这个ts和webpack配置
这是tsconfig
{
"compilerOptions": {
"target": "es5",
"module": "es2015",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": ["es6", "dom"],
"noImplicitAny": true,
"suppressImplicitAnyIndexErrors": true,
"typeRoots": [
"node_modules/@types/"
]
},
"exclude": [
"node_modules"
]
}
这是webpack.config.js
var path = require('path');
var webpack = require('webpack');
var UglifyJSPlugin = require('uglifyjs-webpack-plugin');
module.exports = {
entry: {
'polyfills': './src/polyfills.ts',
'app': './src/main.ts'
},
output:{
path: path.resolve(__dirname, './public'),
publicPath: '/public/',
filename: "[name].js"
},
resolve: {
extensions: ['.ts', '.js']
},
module:{
rules:[
{
test: /\.ts$/,
use: [
{
loader: 'awesome-typescript-loader',
options: { configFileName: path.resolve(__dirname, 'tsconfig.json') }
} ,
'angular2-template-loader'
]
}
]
},
plugins: [
new webpack.ContextReplacementPlugin(
/angular(\\|\/)core/,
path.resolve(__dirname, 'src'),
{}
),
new UglifyJSPlugin()
]
}
这是我的项目根源
但是当我运行项目时，我得到了那些错误 .
[at-loader]中的错误./node_modules/@types/node/index.d.ts:6208:55 TS2304：找不到名称'Map' . [at-loader]中的错误./node_modules/@types/node/index.d.ts:6215:55 TS2304：找不到名称'Set' .

安装类型corejs
npm install --save-dev @types/core-js也将它添加到tsConfig
