Javascript Big.js Typescript错误：当'--隔离模块'；提供标志。ts（2748）

我在Typescript react应用程序中使用了

big.js

，下面的代码

const toFixedRounding = {
  [Rounding.ROUND_DOWN]: RoundingMode.RoundDown,
  [Rounding.ROUND_HALF_UP]: RoundingMode.RoundHalfUp,
  [Rounding.ROUND_UP]: RoundingMode.RoundUp,
};

使用

RoundingMode

当提供'--isolatedModules'标志时，无法访问环境常数枚举。ts（2748）

为什么会出现这种错误，有没有办法解决？谢谢大家!

测试.tsx

import JSBI from "jsbi";
import invariant from "tiny-invariant";
import _Decimal from "decimal.js-light";
import _Big, { RoundingMode } from "big.js";
import toFormat from "toformat";

import { BigintIsh, Rounding } from "../constants";

const Decimal = toFormat(_Decimal);
const Big = toFormat(_Big);

const toSignificantRounding = {
  [Rounding.ROUND_DOWN]: Decimal.ROUND_DOWN,
  [Rounding.ROUND_HALF_UP]: Decimal.ROUND_HALF_UP,
  [Rounding.ROUND_UP]: Decimal.ROUND_UP,
};

const toFixedRounding = {
  [Rounding.ROUND_DOWN]: RoundingMode.RoundDown,      // <==== error occurs here
  [Rounding.ROUND_HALF_UP]: RoundingMode.RoundHalfUp, // <==== error occurs here
  [Rounding.ROUND_UP]: RoundingMode.RoundUp,          // <==== error occurs here
};

从“JSBI”导入JSBI；
从“微小不变量”导入不变量；
从“Decimal.js light”导入_Decimal；
从“Big.js”导入_Big，{RoundingMode}；
从“toFormat”导入toFormat；
从“./constants”导入{BigintIsh，舍入}；
常量十进制=toFormat（_十进制）；
const Big=toFormat（_Big）；
const to significantorounding={
[四舍五入.向下四舍五入]：十进制.向下四舍五入，
[四舍五入.向上四舍五入]：十进制.向上四舍五入，
[四舍五入，四舍五入]：十进制，四舍五入，
};
常数toFixedRounding={
[取整。向下取整]：取整模式。向下取整//
