javascript - Big.js Typescript 错误：当提供 `--isolatedModules` 标志时，无法访问全局常量枚举。ts(2748)

我在一个 Typescript React 应用中使用 big.js，以及以下代码

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

使用 RoundingMode 时给出以下错误

在提供 '--isolatedModules' 标志时，无法访问环境常量枚举。ts(2748)

为什么会发生这个错误，有没有办法解决？谢谢！

test.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
};
