如何修复错误[ERR_ASSERTION]：构造函数已经存在！ （“inversify-restify-utils”：“^ 3.4.0”）和（“inversify-restify-utils”：“^ 3.4.0”）

Question

node_modules / restify-errors / lib / index.js：67 assert.equal（typeof module.exports [name]，'undefined'，^ AssertionError [ERR_ASSERTION]：构造函数已经存在！

"inversify": "^4.13.0",
"inversify-binding-decorators": "^4.0.0",
"inversify-restify-utils": "^3.4.0",
"js-yaml": "^3.12.0",
"lodash": "^4.17.11",
"reflect-metadata": "^0.1.12",
"restify": "^7.2.1",
"restify-cors-middleware": "^1.1.1",
"winston": "^3.0.0"

private setPlugins(): void {
        const cors = corsMiddleware(this.config.cors);

        this.server.pre(cors.preflight);

    this.server.use(
        restify.plugins.acceptParser(this.server.acceptable),
        cors.actual
    );
}

它应该能够运行

npm run serve

该模块附带了一组构造函数，可用于使用默认状态代码创建Error对象。

npm i restify-errors --save-dev

只需将此软件包安装到您的项目中，因为在您使用Inversifyjs时需要它
