node.js - 未定義 File:使用 TypeScript 創建 File 物件時
我在 Node.js 中用 TypeScript 編寫了一個程式(不是 API 或網頁應用程式),只是個控制台應用程式。我已經配置了 TypeScript 設定。但當我建立一個 File 物件時,它給我錯誤。
UnhandledPromiseRejectionWarning: ReferenceError: File is not defined
My Code
// .......
var file = new File(["asdasdsa"], 'metadata.json');
console.log(file.name);
// ......
ts 配置 json 內容

關於 TypeScript 配置,我有遺漏什麼嗎。我想用 TypeScript 建立一個 File 物件
答案#1
我在使用 node v18.15.0 時遇到這個錯誤。更新到 v20.10.0 修正了這個問題,而且在我的 ts-node 腳本中 File 已經被定義,無需任何匯入。
