獲取錯誤模塊未找到：'dgram'in postgres heroku app

Question

我正在嘗試將postgres插件合併到同樣使用react的heroku應用程序中。根據該SO線程

> heroku local web 
[OKAY] Loaded ENV .env File as KEY=VALUE Format 
[WARN] ENOENT: no such file or directory, open 'Procfile' 
[OKAY] package.json file found - trying 'npm start' 
9:21:18 PM web.1 | > test-app@0.1.0 start /Users/oliverpike/dev/heroku/ofp-react 
9:21:18 PM web.1 | > react-scripts start 
9:21:19 PM web.1 | Starting the development server... 
9:21:25 PM web.1 | Failed to compile. 
9:21:25 PM web.1 | Error in ./~/dns/~/native-dns/lib/server.js 
9:21:25 PM web.1 | Module not found: 'dgram' in /Users/oliverpike/dev/heroku/ofp-react/node_modules/dns/node_modules/native-dns/lib 

顯然DGRAM內置節點：當我嘗試在本地運行的應用程序，我碰到下面的錯誤 Does node.js have built-in support for UDP(datagams)?

這裏的NPM的輸出I DGRAM：

> npm i dgram 
dgram@1.0.1 node_modules/dgram

顯然你試圖在客戶端應用程序中使用Sequelize和PG節點模塊，但是這些模塊只是在節點環境中運行，不應該在客戶端應用程序中使用。
