rn 如何使用node模块的代码

[leo-lucky-hub]

npm install --save universal-speedtest

import { UniversalSpeedtest, SpeedUnits } from "universal-speedtest";

const universalSpeedtest = new UniversalSpeedtest({ measureUpload: true, downloadUnit: SpeedUnits.MBps }); universalSpeedtest.runSpeedtestNet().then((result) => { console.log(result); });

错误如下： error: Error: Unable to resolve module perf_hooks from /Users/develop/ReactNative/Test/node_modules/universal-speedtest/dist/Speedtest.js: perf_hooks could not be found within the project or in these directories: node_modules 2 | Object.defineProperty(exports, "__esModule", { value: true }); 3 | exports.Speedtest = void 0; > 4 | const perf_hooks_1 = require("perf_hooks"); | ^ 5 | const path = require("path"); 6 | const worker_threads_1 = require("worker_threads"); 7 | const UrllibHelper_1 = require("./helpers/UrllibHelper"); at ModuleResolver.resolveDependency (/Users/develop/ReactNative/Test/node_modules/metro/src/node-haste/DependencyGraph/ModuleResolution.js:158:15) at DependencyGraph.resolveDependency (/Users/develop/ReactNative/Test/node_modules/metro/src/node-haste/DependencyGraph.js:231:43) at Object.resolve (/Users/develop/ReactNative/Test/node_modules/metro/src/lib/transformHelpers.js:129:24) at resolve (/Users/develop/ReactNative/Test/node_modules/metro/src/DeltaBundler/traverseDependencies.js:396:33) at /Users/develop/ReactNative/Test/node_modules/metro/src/DeltaBundler/traverseDependencies.js:412:26 at Array.reduce ()enter code here at resolveDependencies (/Users/develop/ReactNative/Test/node_modules/metro/src/DeltaBundler/traverseDependencies.js:411:33) at processModule (/Users/develop/ReactNative/Test/node_modules/metro/src/DeltaBundler/traverseDependencies.js:140:31) at async addDependency (/Users/develop/ReactNative/Test/node_modules/metro/src/DeltaBundler/traverseDependencies.js:230:18) at async Promise.all (index 4)

个人理解，是因为无法使用@type/node/perf_hooks.d.st里面的代码

rn的运行环境不是node，并不能直接使用依赖node模块的代码

[leo-lucky-hub]

那应该如何使用node的模块呢

[sunnylqm]

有替代品的话用替代品，没有的话没辙

rn的运行环境不是node，那它的运行环境是什么？
