当我运行`ngnew`时，npm有一个依赖问题
我跑ng new在终端。我最终收到了 npm 错误
- 新建文件夹
ng new在新文件夹中运行- 设置名称并接受默认值（并使用 SCSS）
- 看着它在最后创建文件和错误

回答
我在一个新项目等中遇到了同样的问题。
在生成的内容中，package.json您应该看到一行内容，"jasmine-core": "~3.7.0"但似乎其他依赖项（我相信karma基于此处的错误输出）需要jasmine-core3.8.0 或更高版本。只需编辑说"jasmine-core": "~3.7.0",是的行，"jasmine-core": "~3.8.0",然后手动运行npm install，它应该会成功。
然后，您应该能够ng serve --open从同一目录运行并让它运行得很好。
