我正在尝试使用webpack 2和typescript 2配置我的angular 2,并且我遇到了Duplicate Identifier错误。我已经搜索了多种解决方案,到目前为止还没有人帮助过。
错误:
typings\globals\core-js\index.d.ts
`Duplicate identifier 'PropertyKey'
typings\globals\core-js\index.d.ts
`Duplicate identifier 'Promise'
typings\globals\es6-promise\index.d.ts
`Duplicate identifier 'Promise'
typings\globals\es6-shim\index.d.ts
`Duplicate identifier 'PropertyKey'
我尝试将环境依赖项添加到我的typings.json文件中但没有成功,并且还试图完全删除globalDependencies并且只是保留ambientDependencies:
{
"globalDependencies": {
"core-js": "registry:dt/core-js#0.0.0+20160725163759",
"es6-shim": "github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd",
"es6-collections": "registry:dt/es6-collections#0.5.1+20160316155526",
"es6-promise": "registry:dt/es6-promise#0.0.0+20160614011821",
"jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
"node": "registry:dt/node#6.0.0+20160909174046"
},
"ambientDependencies": {
"es6-shim": "registry:dt/es6-shim#0.31.2+20160215162030"
}
}
我已经尝试排除tsconfig.json文件中的整个typings目录,但这会导致其他错误,例如:
node_modules\@angular\platform-browser\src\facade\collection.d.ts:8:8
Cannot find name 'Map'.
我当前的tsconfig.json如下:
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": false,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false,
"suppressImplicitAnyIndexErrors": true
},
"exclude":[
"node_modules",
"typings/main",
"typings/main.d.ts"
],
"awesomeTypescriptLoaderOptions":{
"useWebpackText":true
}
}
我还尝试将以下内容添加到tsconfig.json的exclude数组中:
"browser"
"browser.d.ts"
最后,我的webpack.config.js如下:
var webpack = require('webpack');
var HtmlWebPackPlugin = require('html-webpack-plugin');
var path = require('path');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
context: path.resolve('app'),
entry: {
'app':'./main.ts'
},
output:{
path: path.resolve('dist'),
publicPath:'/',
filename: 'bundle.js'
},
resolve:{
extensions:['', '.js', '.ts']
},
devtool:'module-inline-source-map',
watch:true,
devServer: {
historyApiFallback: true,
stats: 'minimal'
},
module:{
loaders: [
{
test:/\.ts$/,
exclude:/node_modules/,
loaders: ['awesome-typescript-loader', 'angular2-template-loader']
},
{
test: /\.html$/,
loader: "html"
},
{
test: /\.css$/,
exclude: path.resolve('app'),
loader: ExtractTextPlugin.extract({fallbackLoader: 'style-loader', loader: 'css-loader'})
},
{
test: /\.css$/,
include: path.resolve('app'),
loader: 'raw'
},
{
test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)?(\?v=[0-9]\.[0-9]\.[0-9])?$/,
loader: 'file?name=fonts/[name].[hash].[ext]?'
},
{
test: /\.eot(\?v=\d+\.\d+\.\d+)?$/,
loader:'file'
},
{
test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/,
loader:'url?limit=10000&mimetype=application/octet-stream'
},
{
test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
loader:'url?limit=10000&mimetype=image/svg+xml'
}
]
},
plugins: [
new ExtractTextPlugin("styles.css"),
new HtmlWebPackPlugin({
template: path.resolve('app/index.html')
}),
new webpack.ProvidePlugin({
$: "jquery",
jquery:"jquery",
jQuery:"jquery",
"windows.jQuery":"jquery",
"window.Tether":'tether'
})
]
}
如果有人对此有任何见解,我将非常感谢您的帮助。
谢谢!
只是在Dave V提供答案后显示更改的更新:
以下文件夹已从typings目录中删除:
globals/es6-promise
globals/es6-shim
browser
输入root中的index.d.ts删除了以下引用:
/// <reference path="globals/es6-promise/index.d.ts" />
/// <reference path="globals/es6-shim/index.d.ts" />
另外,我在tsconfig.json排除数组中添加了"typings/browser.d.ts"
,因为它引用了es6-shim
内的browser/ambient
:
"exclude":[
"node_modules",
"typings/main",
"typings/main.d.ts",
"typings/browser.d.ts"
]
答案 0 :(得分:1)
您无法使用es6-promise
和core-js
,因为它们都涵盖Promise
概念,并且有自己的定义。您只需选择一个(如果您使用的是Angular,则建议使用core-js
)。
