接收TS2304：找不到名称'文件'| TS2304：运行“npm run tsc”命令时找不到名称“ReadableStream”

Posted 2021-04-04

我有一个使用“watson-developer-cloud”模块的nodejs应用程序。使用“npm install --save watson-developer-cloud”包含此模块。

我在运行“npm run tsc”时看到了下面的问题。

node_modules/ibm-cloud-sdk-core/lib/content-type.d.ts(4,35): error TS2304: Cannot find name 'File'.
node_modules/ibm-cloud-sdk-core/lib/content-type.d.ts(4,42): error TS2304: Cannot find name 'ReadableStream'.

我在Mac上运行它。节点版本10.15.3。我发现很少有文章要求设置节点bin目录和重新加载终端的路径。我这样做了 - 虽然又遇到了同样的问题。

node_modules/ibm-cloud-sdk-core/lib/content-type.d.ts(4,35): error TS2304: Cannot find name 'File'.
node_modules/ibm-cloud-sdk-core/lib/content-type.d.ts(4,42): error TS2304: Cannot find name 'ReadableStream'.

答案

File和ReadableStream类型在dom TypeScript库中定义。

尝试将其添加到您的tsconfig.json：

{
  ...
  "compilerOptions": {
    "lib": [
      ...
      "dom"
    ]
  }
}
