知道可能是什么原因吗？

附注实际构建基于 Brave，准确地说是版本 1.48.x - https://github.com/brave/brave-browser/tree/1.48.x 但无论如何，构建错误发生在 chrome 的代码中......

Answer 1

同时，我很幸运找到了答案，但我很抱歉在这里提出了这个问题。

答案就在 GitHub 上的 Brave 问题中：https://github.com/brave/brave-browser/issues/21178

基本上在最顶层的 tsconfig.json 文件（包含 chrome 的 src 文件夹的文件夹）中从 es5 更改为 esnext

Answer 2

我浏览了

tsconfig.json

并将这些视为配置，

{
  "compilerOptions": {
    "target": "es5",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": true,
    "noEmit": true,
    "esModuleInterop": true,
    "module": "esnext",
    "moduleResolution": "bundler",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "jsx": "preserve",
    "incremental": true,
    "plugins": [
      {
        "name": "next"
      }
    ],
    "paths": {
      "@/*": ["./src/*"]
    }
  },
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx", ".next/types/**/*.ts"],
  "exclude": ["node_modules"]
}

我不知道为什么已经给出了 es5 而我正在使用 nextJS 14.0.5

我将

"target": "es5"

更改为

"target": "es2017"

并且成功了！ 这是我更改后的 tsconfig.json，

{
  "compilerOptions": {
    "target": "es2017",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": true,
    "noEmit": true,
    "esModuleInterop": true,
    "module": "esnext",
    "moduleResolution": "bundler",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "jsx": "preserve",
    "incremental": true,
    "plugins": [
      {
        "name": "next"
      }
    ],
    "paths": {
      "@/*": ["./src/*"]
    }
  },
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx", ".next/types/**/*.ts"],
  "exclude": ["node_modules"]
}

所以，从技术上来说我们需要改变
