TypeScript经常出现问题，并且首选导入而不是需要

Question

只要有可能，我就会尝试在require上使用import，但在某些情况下，这会破坏类型检查。处理这个问题的正确方法是什么？是否可以强制转换导入？不是所有的require都可以用import替代吗？

左图：Property 'get' does not exist...

右图:用import * as convict from "convict";代替require("convict");

左图：

"use strict";

import * as Busboy from "busboy";
import * as convcit from "convict";
import * as config from "./config";
import * as express from "express";
import * as helmet from "helmet";
import * as logger from "morgan";
import * as path from "path";

import * as requestDebug from "request-debug";
import * as requestJs from "request";

// [ts] Property 'get' does not exist on type 'typeof "PrizmDoc-Node.js-Sample/config"'.
if (config.get("env") !== "production") {
    requestDebug(requestJs);
}

...

右图：

//let convict = require("convict");

import * as convict from "convict";

const config = convict({
    "env": {
        "doc": "The application environment.",
        "format": ["production", "development", "test"],
        "default": "development",
        "env": "NODE_ENV"
    },

...

module.exports = config;

不幸的是，这是您的一个依赖项convict的类型问题。查看@types/convict源代码：

https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/convict/index.d.ts#L122

他们使用export = ...导出定义，根据Typescript手册：

https://www.typescriptlang.org/docs/handbook/modules.html (参见“export =和import = require()”标题)

中断import * from ...导入。所以，你有点被困在这个问题上了。
