Max*_*ich 5 asp.net asp.net-mvc typescript definitelytyped webpack
我对使用TypeScript和Webpack还是比较陌生,但是不幸的是,我的类型声明似乎一直无法解决,因此一直遇到问题。
简单来说,我的项目是一个ASP.NET MVC React应用程序,它使用NPM,TypeScript和Webpack来管理JavaScript依赖项。我遇到的问题是,尽管我的项目可以成功编译,但我180 errors看起来像这样。
Run Code Online (Sandbox Code Playgroud)TS2717 (TS) Subsequent property declarations must have the same type. Property 'webview' must be of type 'DetailedHTMLProps<WebViewHTMLAttributes<HTMLWebViewElement>, HTMLWebViewElement>', but here has type 'DetailedHTMLProps<WebViewHTMLAttributes<HTMLWebViewElement>, HTMLWebViewElement>'.
现在,如果我通过单击类型并按“转到定义”仔细看一下,可以清楚地看到我的项目为同一类型定义了两个引用,如下所示:
问题在于,这两个文件似乎都是我的项目tsconfig.json文件的要求,因为如果没有它们,它们将无法编译。
我的tsconfig.json看起来像这样:
{
"compilerOptions": {
"module": "commonjs",
"moduleResolution": "node",
"target": "es5",
"sourceMap": true,
"lib": [ "es5", "es2017", "dom"]
"removeComments": true,
"typeRoots": [
"/node_modules/@types",
"/Types/"
]
},
"compileOnSave": false,
"exclude": [
"/node_modules/",

我的package.json文件如下所示:

现在,我怀疑这个问题与tsconfig.json文件中的行有关,"lib": [ "es5", "es2017", "dom"]但是如果删除这些引用中的任何引用,则我的项目将无法编译,因为显然我的某些类型是在这些库引用中定义的。
谁能帮助我指导如何解决此问题的正确方向,并在ASP.NET TypeScript中正确引用DOM和React?
编辑:我还尝试过更改tsconfig.json文件以删除“ lib”引用(假设可以使用Polyfill)到“ lib”:[]。但是问题仍然存在。

当您在不同版本中拥有依赖项和具有相同依赖项的子模块时,会出现此错误。解决此问题的正确方法是在您的package.json. 以下示例解释了如何“解决”:package.json
{
"name": "project",
"version": "1.0.0",
"dependencies": {
"left-pad": "1.0.0",
"c": "file:../c-1",
"d2": "file:../d2-1"
},
"resolutions": {
"d2/left-pad": "1.1.1",
"c/**/left-pad": "^1.1.2"
}

文档参考:https ://classic.yarnpkg.com/en/docs/selective-version-resolutions/
我发现了以下 github 问题,我非常确定它确定了您所面临问题的根本原因: https: //github.com/DefinitelyTyped/DefinitelyTyped/issues/25145
因此,您将在版本 16.3.9 获得 @types/react,在版本 16.0.5 获得 @types/react-dom,因为您明确要求了这些。然而,@types/react-dom列出了对@types/react的依赖,如下所示:
"@types/react": "*"
[this]解释为“@types/react 的最新版本”,因此它会安装该包的附加版本。
因此,您将同时使用 types 包的版本 v16.3.9 和 v16.3.12,这会导致错误。
我知道有两种方法可以解决这个问题:
- 更新到 package.json 中 @types/react 包的最新版本
- 将解决方案部分添加到 package.json 中,以告诉 Yarn 以不同的方式解决依赖关系。
由于上述反馈,我相信我已经找到了解决问题的方法。
package.json在文件中创建对包的手动引用@types/react。
“devDependency”:{“@types/react”:“16.4.13”}
我的最终 package.json 文件如下所示:

"react-dom": "16.4.2"

和 tsconfig.json 像这样:
