嗨，我在运行ng serve命令时遇到问题。我的 package.json 文件是

}

在运行 ng serve 时，我得到了这个

node_modules/graphql-tag/lib/index.d.ts(2,57) 中的错误：错误 TS1005：“，”预期。node_modules/graphql-tag/lib/index.d.ts(2,63): 错误 TS1005: ',' 预期。i ∩╜ówdm∩╜ú：编译失败。

以下是错误消息的屏幕截图。请帮我解决。先感谢您！！

我很确定这是一个依赖问题。

您的 Angular 项目确实已经过时（请查看此页面https://angular.io/guide/releases#support-policy-and-schedule），您可能应该花时间将其升级到最新版本。我也建议增加你的依赖版本。您使用的是非常旧的 angular-apollo v1.5，可能与您当前的 graphql-tag 不兼容。如果您没有硬锁定依赖项版本，则很难调试过时的环境。

使用ng update,npm outdated和npm update使您的项目尽可能保持最新。也许删除你的 node_modules 和 package-lock.json 并运行npm install以确保你有一个合适的开发环境。

如果没有 stackblitz 或 github 存储库，将很难为您提供更多帮助。
