我尝试创建新的 Angular 项目并收到此错误。我在这里粘贴了我的错误以及 Angular 的版本及其使用的依赖项（ng 版本）。我使用安装程序安装了 Node.js，并使用 cmd 命令安装了 Angular cli。但我无法创建新项目（ng new project-name）请帮我解决这个问题。提前致谢

这是一些过时的软件包在 angular-cli 中出现的错误，它已在 github 的存储库中解决，但他们尚未将其发布到 npmjs ，您可以通过两种方式解决：

1. 安装软件包时使用“--legacy-peer-deps --force”
2. 在“jasmine”处更新 package.json，就像https://github.com/angular/angular-cli/commit/b34ed5c4007f9ef08b370219081b4d23f9f24fb8中的最新提交一样

这是 angular-cli github 存储库上此错误的一个未解决问题https://github.com/angular/angular-cli/issues/20719
