Angular Ubuntu上出现macOS上没有发生的错误

当我将我的应用程序部署到Ubuntu并运行ng b-prod时，它给出了下面的错误，但是在安装npm后，在两个系统上新签出的完全相同的项目在macOS上没有给出错误

另外，我已经运行了数周，没有更改提到的CSS文件，它以前在Ubuntu box上运行。两个系统上都更新了全局npm包，且版本相同

它声称在“/home/ubuntu/front/src”中找不到“@angular/material/core/theming/prebuild/indigo pink.css”，但很明显该文件位于node_模块中

src/styles.css中有问题的行是：

@导入“~@angular/material/core/theming/prebuild/indigo-pink.css”

正如我所说的，这在macOS中100%的工作正常，并且一直工作到今天早上。有什么问题吗

也许，因为你使用的是不同版本的角度材质2。 在beta.3版中，您需要使用此链接更改预构建的主题

@import '~@angular/material/prebuilt-themes/indigo-pink.css';

Wow-谢谢。显然，我犯了一个错误，没有完全更新我的开发环境。你是个救生员！我很乐意帮忙！
