错误：此模块使用'export ='声明，只能使用使用“allowSyntheticDefaultImports”时默认导入旗帜。文件错误：

1 从“表单数据”导入表单数据； ~~~~~~~~

node_modules/@kintone/rest-api-client/node_modules/form-data/index.d.ts:10:1

10 导出=表单数据； ~~~~~~~~~~~~~~~~~~~~

这是文件的代码：

【解决方案1】：

请尝试将allowSyntheticDefaultImports: true 添加到tsconfig，看看是否能解决问题。

这是一个类似查询的链接： This module is declared with using 'export =', and can only be used with a default import when using the 'esModuleInterop' flag

此外，以下是一些编译器选项： https://www.typescriptlang.org/docs/handbook/compiler-options.html

希望这会有所帮助。

【解决方案2】：

您应该将 allowSyntheticDefaultImports 设置为 false 而不是 true
