错误：架构验证失败，并出现以下错误：数据路径“”不应具有其他属性（项目）

Question

将应用程序从5号角迁移到6号角后，运行ng时会弹出以下错误。

模式验证失败，并出现以下错误：数据路径“”不应具有其他属性（项目）。错误：模式验证失败，并出现以下错误：数据路径“”不应具有其他属性（项目）。在MergeMapSubscriber._registry.compile.pipe.operators_1.concatMap.validatorResult [作为项目]（... / TemplateApp / me-cmf-web-template-angular / node_modules / @ angular-devkit / core / src / workspace / workspace中。 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 ）（位于MergeMapSubscriber.Subscriber._next（... / me-cmf-web-template-angular/node_modules/@angular-devkit/core/node_modules/rxjs/internal/operators/mergeMap.js：55：18）中。

我假设错误与.angular.json文件有关，该文件是从.angular-cli.json重命名的。

我的.angular.json文件如下：

我应该重新构造json文件吗？

任何帮助都会很棒。

Answer 1

我的应用程序的角度为 7.2.3

从 angular.json 中删除 "es5BrowserSupport": true。并且 npm start 现在可以工作了。

Answer 2

只需转到 angular.json 文件并删除

“extractCSS”：正确

于

生产部分。

Answer 3

该问题通常是由于package.json文件中的版本不匹配所致。

在Angular 7应用中，我已更改"@angular-devkit/build-angular": "^0.800.2"为"@angular-devkit/build-angular": "~0.7.0"。

然后npm install删除后运行命令node_modules。

放在一边：^小心使用。如果所使用的程序包发生重大变化，则您的工作代码将来可能无法正常工作。

Answer 4

当我遇到版本错误问题时，以下命令对我有用：

第一次运行：

npm update

第二次运行：

ng update

第三次运行：（它将更新所有不匹配的包）

ng update --all --force

Answer 5

First:

npm uninstall @angular-devkit/build-angular

Next:

npm install @angular-devkit/build-angular@0.12.4

Answer 6

从 9 到 10 的 Angular 升级非常简单（所有其他详细信息都在这里：https : //update.angular.io/?v=9.0-10.0）：

确保您的包文件处于版本控制中并且所有更改都已提交。这将覆盖您的包文件。最好在新的实验分支中尝试。

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

在新模式中，不再允许使用 key es5BrowserSupport，在您的 中删除以下行angular.json：

"es5BrowserSupport": true

然后简单地重新启动您的应用程序：

npm start

Answer 7

更改package.json自：

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

到：

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

Answer 8

因为我解决了这个问题，所以我认为把它贴在这里会很好。

我将文件名 .angular.json 更改为 angular.json 并替换了其中问题的一些属性。

我通过用 angular 官方文档中的属性替换 angular.json 文件来更改文件。

官方Angular 更新指南提供了有关如何更新版本的分步指南。
