将应用程序从 Angular 5 迁移到 6 后，运行 ng serve 时会出现以下错误。

架构验证失败，并显示以下错误： 数据路径“”不应有其他属性（项目）。 错误：架构验证失败，并显示以下错误： 数据路径“”不应有其他属性（项目）。 在 MergeMapSubscriber._registry.compile.pipe.operators_1.concatMap.validatorResult [as project] (.../TemplateApp/me-cmf-web-template-angular/node_modules/@angular-devkit/core/src/workspace/workspace.js:210:42) 在 MergeMapSubscriber._tryNext (/.../me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/operators/mergeMap.js:65:27) 在 MergeMapSubscriber._next (.../me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/operators/mergeMap.js:55:18) 在 MergeMapSubscriber.Subscriber.next (/home/training/Attinad_Projects/TemplateApp/me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/Subscriber.js:64:18) 在 MergeMapSubscriber.notifyNext (.../TemplateApp/me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/operators/mergeMap.js:84:26) 在 InnerSubscriber._next (.../me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/InnerSubscriber.js:25:21) 在 InnerSubscriber.Subscriber.next (/.../me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/Subscriber.js:64:18) 在 MapSubscriber._next (.../me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/operators/map.js:52:26) 在 MapSubscriber.Subscriber.next (/.../me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/Subscriber.js:64:18) 在 SwitchMapSubscriber.notifyNext (.../me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/operators/switchMap.js:77:26)

我认为错误出现在.angular.json文件中，我将其从.angular-cli.json重新命名。

我的.angular.json 文件如下：

{
    "$schema": "./node_modules/@angular/cli/lib/config/schema.json",

如果需要的话，我应该如何重新组织JSON文件呢？

这个问题通常是由于你的package.json文件中版本不匹配引起的。

在我的Angular 7应用程序中，我将"@angular-devkit/build-angular": "^0.800.2"更改为"@angular-devkit/build-angular": "~0.7.0"。

然后我删除了node_modules后运行了命令npm install。

另外：要小心使用^。如果所使用的软件包发生重大变化，您的可工作代码可能在未来无法正常工作。

同时使用相同的package-lock.json文件也可以解决该问题。

它对我也起作用了，谢谢。不知道为什么它在0.800.2版本中不能工作？ - Gajen
我猜这是由于主要版本不匹配造成的。 - Sasikumar

@Sasikumar 谢谢，删除 node_modules 并运行 npm i 对我有用。我的问题是我有两个分支，其中一个有更新的 Angular 版本。 - Elhakim

我的应用程序是基于Angular 7.2.3的。

从angular.json中删除 "es5BrowserSupport": true。 然后现在运行npm start就可以了。

将 es5BrowserSupport 设置为 true 是提高首次加载性能的好方法。禁用它并不是一个解决方案... - C0ZEN

你需要从 angular.json 中移除 es5BrowserSupport 这个键，因为在 Angular ^v10 中不再允许使用它。 - user3025289

只需打开 angular.json 文件并删除

"extractCss": true

在

生产环境部分。

当我遇到版本错误问题时，以下命令对我有效：

首先运行：

npm update

第二次运行：

ng update

第三次运行： （它将更新所有不匹配的软件包）

npm update --all --force

ng update --all --force wth error Error: Unknown argument: all - Bill
“ng update --all --force”是一个打字错误。应该更新为“npm update --all --force”。 - Danny Bullis

首先：

npm uninstall @angular-devkit/build-angular

下一步：
npm install @angular-devkit/build-angular@0.12.4
10

将 Angular 从 9 升级到 10 非常简单（所有额外的详细信息都在这里：https://update.angular.io/?v=9.0-10.0）：

确保您的软件包文件已经版本控制并且所有更改都已提交。这将覆盖您的软件包文件。最好在新的实验分支中尝试它。

npm install -g npm-check-updates
ncu -u
ng update --all --force

在新架构中，不再允许使用键 es5BrowserSupport，请从您的 angular.json 文件中删除以下行：

"es5BrowserSupport": true

那么只需重新启动您的应用程序：

npm start

自从我解决了这个问题，我想在这里发布一下。
我将文件名从.angular.json更改为angular.json，并替换其中的一些属性。

我通过用官方Angular文档中的属性替换angular.json文件来更改文件。
官方Angular更新指南提供了逐步更新版本的指南。

将package.json文件从以下代码更改为:

"@angular-devkit/build-angular": "^0.13.5",

致：

"@angular-devkit/build-angular": "^0.12.1",

angular.json文件的格式需要符合Angular6的要求。您可以检查下面的angular.json文件或者创建一个新的Angular6项目，然后检查'project'头部的格式。

我遇到了类似但并非完全相同的问题（也出现在 angular.json 文件中）：

模式验证失败，具有以下错误： 数据路径"['server']"不应该具有额外的属性(scripts)。 错误： 模式验证失败，具有以下错误： 数据路径"['server']"不应该具有额外的属性(scripts)。 at MergeMapSubscriber._registry.compile.pipe.operators_1.concatMap.validatorResult [as project] (D:\Angular7\uHome\node_modules@angular-devkit\core\src\workspace\workspace.js:215:42) at MergeMapSubscriber._tryNext (D:\Angular7\uHome\node_modules\rxjs\internal\operators\mergeMap.js:69:27) at MergeMapSubscriber._next (D:\Angular7\uHome\node_modules\rxjs\internal\operators\mergeMap.js:59:18) at MergeMapSubscriber.Subscriber.next (D:\Angular7\uHome\node_modules\rxjs\internal\Subscriber.js:67:18) at MergeMapSubscriber.notifyNext (D:\Angular7\uHome\node_modules\rxjs\internal\operators\mergeMap.js:92:26) at InnerSubscriber._next (D:\Angular7\uHome\node_modules\rxjs\internal\InnerSubscriber.js:28:21) at InnerSubscriber.Subscriber.next (D:\Angular7\uHome\node_modules\rxjs\internal\Subscriber.js:67:18) at MapSubscriber._next (D:\Angular7\uHome\node_modules\rxjs\internal\operators\map.js:55:26) at MapSubscriber.Subscriber.next (D:\Angular7\uHome\node_modules\rxjs\internal\Subscriber.js:67:18) at SwitchMapSubscriber.notifyNext (D:\Angular7\uHome\node_modules\rxjs\internal\operators\switchMap.js:86:26)

我不得不从我的 angular.json 文件中删除了 scripts 属性……分享这些信息是为了帮助未来遇到此问题的人。

当我将 Angular 从版本 8 升级到 10 时，我遇到了非常类似的错误，即 Schema validation failed with the following errors: Data path "" should NOT have additional properties(serverTarget)..

解决方案是从下面的 "serve" 中删除所有 "serverTarget" 引用。以下是错误的内容：

"serve": {
  "builder": "@angular-devkit/build-angular:dev-server",
  "options": {
    "browserTarget": "my_app:build"
    "serverTarget": "my_app:server"
  },
  "configurations": {
    "production": {
      "browserTarget": "my_app:build:production",
      "serverTarget": "my_app:server:production"
    }
  }
},

以下内容是正确的并且编译成功的：
"serve": {
  "builder": "@angular-devkit/build-angular:dev-server",
  "options": {
    "browserTarget": "my_app:build"
  },
  "configurations": {
    "production": {
      "browserTarget": "my_app:build:production"
    }
  }
},

对于那些正在使用 Angular Universal 的人来说，这是一个奖励。如果你想在本地运行SSR，那么确实需要 serverTarget。但是为了做到这一点，您必须在 angular.json 中创建一个新部分，例如：
"serve-ssr": {
  "builder": "@nguniversal/builders:ssr-dev-server",
  "options": {
    "browserTarget": "my_app:build",
    "serverTarget": "my_app:server"
  },
  "configurations": {
    "production": {
      "browserTarget": "my_app:build:production",
      "serverTarget": "my_app:server:production"
    }
  }
},

然后运行命令： ng run my_app:serve-ssr。

实际上，当我将Angular从版本10升级到8并想要改进一些东西时，我遇到了这个错误。然后我理解错了serverTarget的设置，并把它搞砸了。希望这能对那些在项目中使用Angular Universal的人有所帮助。
