角度依赖或版本问题。怎么解决？

Question

您能帮我合并下面项目依赖项的版本吗（请不要使用版本 17，而应使用旧版本）！

这是我的

package.json

文件：

"dependencies": {
    "@angular/animations": "^15.0.0",
    "@angular/common": "^15.2.9",
    "@angular/compiler": "^15.0.0",
    "@angular/core": "^15.0.0",
    "@angular/forms": "^15.0.0",
    "@angular/platform-browser": "^15.0.0",
    "@angular/platform-browser-dynamic": "^15.0.0",
    "@angular/platform-server": "^15.0.0",
    "@angular/router": "^15.0.0",
    "@angular/ssr": "15.0.0",
    "express": "^4.18.2",
    "rxjs": "~7.5.0",
    "tslib": "^2.3.0",

  },
  "devDependencies": {
    "@angular-devkit/build-angular": "^15.0.0",

    "@types/jasmine": "~4.3.0",
    "@types/node": "^18.18.0",
    "jasmine-core": "~4.5.0",
    "karma": "~6.4.0",

    "karma-jasmine": "~5.1.0",
    "karma-jasmine-html-reporter": "~2.0.0",

错误信息：

  Data path "" must have required property 'browserTarget'.

我在

angular.json

中尝试了无数版本和修改。他们都没有找到解决方案。

Answer 1

该问题通常是由于 package.json 文件中的版本不匹配造成的。

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

然后我执行以下步骤 删除节点模块 删除 package-lock.json npm 我

旁白：小心使用^。如果使用的包发生重大变化，您的工作代码将来可能无法工作。

或 从 angular.json 文件中删除这两行：

"vendorSourceMap":"true", “evalSourceMap”：“true”。
