我正在将一个 Angular 应用部署到 Netlify。此应用已部署多次，没有出现任何问题。最近，在添加新功能时，我将应用从 Angular 5 升级到 7，并升级了许多依赖项。现在构建失败，信息非常少。

在 Netlify 上，我使用的构建命令是： ng build --target=development --environment=staging 用于开发和 ng build --target=production --environment=prod 用于生产。

Netlify 上的日志是：

我注意到 --target= 和 --environment= 未被处理。在过去的成功部署日志中，这些选项运行良好。因此我假设部署问题与此有关。

有人可以就此提供一些指导吗？

谢谢。
