角度通用-运行node.js时发出警告

我有angular 7站点-我已经将其转换为服务器端渲染（主要指）

我正在AWS上运行使用“Forever”的站点。我总是在我以前的错误日志文件中看到以下错误：

(node:23488) [DEP0005] DeprecationWarning: Buffer() is deprecated due to 
security and usability issues. Please use the Buffer.alloc(), 
Buffer.allocUnsafe(), or Buffer.from() methods instead.

我在代码中没有使用任何类型的缓冲区，所以我猜它可能来自我正在使用的节点模块。从上面的日志消息中，我无法检测哪个模块有问题

我当前的package.json如下所示：

"dependencies": {
  "@angular/animations": "^7.0.0",
  "@angular/common": "^7.0.0",
  "@angular/compiler": "^7.0.0",
  "@angular/core": "^7.0.0",
  "@angular/forms": "^7.0.0",
  "@angular/http": "^7.0.0",
  "@angular/platform-browser": "^7.0.0",
  "@angular/platform-browser-dynamic": "^7.0.0",
  "@angular/platform-server": "^7.0.0",
  "@angular/router": "^7.0.0",
  "@nguniversal/express-engine": "^7.0.2",

  "chart.js": "^2.7.3",

  "express": "^4.16.2",

  "he": "^1.2.0",
  "jquery": "^3.3.1",
  "jw-angular-social-buttons": "^1.0.0",
  "moment": "^2.23.0",
  "ng2-validation": "^4.2.0",
  "primeicons": "^1.0.0",
  "primeng": "^6.1.7",
  "prismjs": "^1.15.0",
  "rxjs": "~6.3.3",
  "ts-loader": "^5.3.2",
  "webpack": "^4.28.3",
  "webpack-cli": "^3.1.2",
  "webpack-dev-server": "^3.1.14",
  "zone.js": "~0.8.26"
} 

有没有办法获取更多日志？我现在可以忽略此错误消息吗

提前谢谢

编辑- My package.json包含以下内容：

"build-both": "ng build --prod --output-path=dist/browser && ng run 
ecokrypt-uiapp:server --configuration=publiclocal 
--output-path=dist/server",
"webpack-server": "webpack --config webpack.server.config.js 
--ouput dist/server.js --progress --colors",
"build-and-pack": "npm run build-both && npm run webpack-server",

当我构建应用程序时（npm运行build and pack）：我在控制台中看到以下内容：我看到2条与某些系统相关的警告。Import（）

迟回答比不回答好

这是webpack cli使用的旧包xhr2，有一个

要解决此问题，请遵循该步骤上的建议：

npm i xhr2--save

能否添加完整的生成日志？在问题中添加了生成日志。您是否解决了此问题？我相信是在角科里诺，我仍然看到同样的错误。唯一的问题是我的网站是工作良好，所以并没有费心去挖它忽略它！其中一个依赖项应根据以下提示更新其代码库：
