node.js - 尝试在工作线程中加载bcrypt时出现“模块未自注册”错误

Question

有问题的样本项目：https://github.com/Suvitruf/bcrypt-child-process-crash-proof

const {Worker, isMainThread} = require('worker_threads');

if(isMainThread)
    console.log("I'm ok, because I'm alpha main");
else
    console.log("I'm sad, because I can't load bcrypt");

const bcrypt = require('bcrypt');

function runTestWorker(workerData) {
    return new Promise((resolve, reject) => {
        const worker = new Worker('./index.js', workerData);

        worker.on('message', resolve);
        worker.on('error', reject);
        worker.on('exit', (code) => {
            if (code !== 0)
                reject(new Error(`Worker stopped with exit code ${code}`));
        })
    })
}

async function run() {
    const result = await runTestWorker('I will crash your app  (｡•́︿•̀｡)');
    console.log(result);
}

if(isMainThread)
    run().catch(err => console.error(err));

如果尝试在工作线程中加载bcrypt，则会出现错误：

Error: Module did not self-register.

    at Module.load (internal/modules/cjs/loader.js:630:32)

    at Object.Module._extensions..js (internal/modules/cjs/loader.js:749:10)

信息：


节点v11.10.0
bcrypt v3.0.4


我该如何解决？

同样的问题，这似乎是bcrypt自身的问题。

解决此问题的临时方法：

const { isMainThread } = require("worker_threads");

var bcrypt;
if (isMainThread) bcrypt = require("bcrypt");

let bcryptFunction = (...param) => {
  if (bcrypt == undefined) return Promise.reject("Not in main threads")
  return bcrypt.hash(...param)
}
