角度迁移（从4迁移到6）警告-无法解决信息流

Question

我几乎没有问题，可以将Angular应用程序从4升级到6。只有这个令人讨厌的警告出现在控制台中：

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但是错误仍然出现。香港专业教育学院也试图添加

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

进入我的tsconfig.json文件。没有任何帮助。此外，通过谷歌搜索我还没有找到一个有用的解决方案。有谁知道得更好吗？

在安装流软件包可解决问题时，有几条评论：

npm install stream --save

在其他来源中，建议使用替换该stream软件包readable-stream，但我知道这不是您的选择。
