我在测试我的 Angular 10.0.3 应用程序时得到一个空白页。这里是 server.js：

const express = require('express');

const app = express();

app.use(express.static('./src'));
app.get('/*', (req, res) =>
    res.sendFile('index.html', {root: './src'}),
);

app.listen(process.env.PORT || 8080);

包.json：

          }
        }
      }
    }},
  "defaultProject": "fsdoblakoangular"
}

当我开始通过ng serve --open它工作正常。但是当我想通过node server.js项目目录启动它时 - 我得到一个空白页。

我正在使用这篇文章，并从底部使用了一个 repo。我认为路径有什么问题 - 脚本无法编译。

这很愚蠢，但是在更改文件后，sctipts - "start": "ng serve"我package.json忘记了构建项目。
