导出默认数据语法错误：使用TypeScript在next.js上构建时意外导出令牌 [英] export default data SyntaxError: Unexpected token export during bulding on next.js using typescript

问题描述

此处提供的代码=>； https://codesandbox.io/s/sweet-mcclintock-dhczx?file=/pages/index.js

尝试将@iconify-icons/cryptocurrency与next.js和TypeScript一起使用时出现初始错误(仅在TypeScript中发生)。

SyntaxError: Unexpected token export

export default data;

并非所有库都会出现此问题。在我看来，在转写过程中，巴别塔的库语法有问题。

然后，我已尝试使用以下代码转换库next-transpile-module以解决该问题。

const withTM = require("next-transpile-modules")([
  "@iconify-icons/cryptocurrency"
]);

module.exports = withTM();

但是发生了一个新问题。

Error: next-transpile-modules - an unexpected error happened when trying to resolve "@iconify-icons/cryptocurrency"
Error: Can't resolve '@iconify-icons/cryptocurrency' in '/sandbox'
    at getPackageRootDirectory (/sandbox/node_modules/next-transpile-modules/src/next-transpile-modules.js:87:11)
    at Array.map (<anonymous>)
    at generateModulesPaths (/sandbox/node_modules/next-transpile-modules/src/next-transpile-modules.js:99:33)

总而言之，转换模块是我试图实现主要目标的方式。可能没有必要。

推荐答案

导出@iconify-icons/cryptocurrency库的方式意味着您需要单独传输您使用的每个图标包。

const withTM = require("next-transpile-modules")([
  "@iconify-icons/cryptocurrency/usdt"
]);

module.exports = withTM();
