Angular 迁移(从 4 到 6)警告 - 无法解析流

Question

我将 Angular 应用程序从 4 升级到 6 时几乎没有遇到任何问题。只有这个令人恼火的警告出现在我的控制台中:

WARNING in ./node_modules/sax/lib/sax.js
Module not found: Error: Can't resolve 'stream' in 'D:\user\app\node_modules\sax\lib'

我已经尝试删除 node_modules 指令并执行 npm install 但错误仍然出现。我也尝试添加

"paths": {
        "sax": [
            "../node_modules/sax/lib/sax.js"
        ]
    }

进入我的tsconfig.json文件。没有任何帮助。另外通过谷歌搜索我还没有找到有用的解决方案。有人可能更了解吗？

有一些评论说安装流包可以解决问题:

npm install stream --save

其他sources ，建议将 stream 包替换为 readable-stream，但我知道这不适合您。
