在 angular 中从量角器迁移到赛普拉斯给出错误

Question

我正在尝试将 Protractor e2e 测试迁移到 cypress。第一步是运行这个命令：ng add @cypress/schematic 一切顺利，但现在当我输入 ng e2e 时出现错误：

An unhandled exception occurred: Job name "..getProjectMetadata" does not exist. See "C:\Users\WAEL~1.ABB\AppData\Local\Temp\ng-Nojsrx\angular-errors.log" for further details.

我正在使用 angular8, "@angular-devkit/build-angular": "0.803.24" 我尝试了 devkit 的所有其他次要版本，但仍然出现相同的错误。有什么线索吗？

angular.json:

"e2e": {
  "builder": "@cypress/schematic:cypress",
  "options": {
    "devServerTarget": "proj:serve",
    "watch": true,
    "headless": false
  },
  "configurations": {
  "production": {
    "devServerTarget": "proj:serve:production"
  }
}

错误日志：

这看起来像是版本控制问题。

您有 angular8 的标签，这是您运行正在使用的版本吗？我注意到 Angular 不再支持 v8 和更低版本。

另外 @cypress/schematic 是今年发布的，可能不兼容。

我测试了 Angular 8 starter app + @cypress/schematic，并尝试运行 ng e2e 给出了同样的错误。

但是，运行宁“标准”赛普拉斯命令

yarn cypress open

or

npx cypress open

将打开 Cypress 运行ner 并在 /cypress/integration 运行下进行测试。

此外，手动启动 Angular 开发服务器 - ng start 以便可以在 http://localhost:4200.
