角材料(8)S2591:找不到名称'require' [英] Angular Material (8) S2591: Cannot find name 'require'

问题描述

我正在尝试将日期/时间记录到javascript控制台中.我收到的错误消息如下，是由下面的代码生成的.

I am trying to log date/time into the javascript console. The error message I am getting is as follows and was generated by the code below.

ETA:该代码确实有效.日期将转到控制台.只是错误消息仍然存在

ETA: the code does work. The dates are going to the console. It is just the Error Message remains

消息:

src/app/kdc/services/customers.api.service.ts(60,9)中的

ERROR:错误TS2591:找不到名称"require".您需要安装类型吗节点的定义?尝试 npm i @ types/node ，然后将 node 添加到tsconfig中的类型"字段.

ERROR in src/app/kdc/services/customers.api.service.ts(60,9): error TS2591: Cannot find name 'require'. Do you need to install type definitions for node? Try npm i @types/node and then add node to the types field in your tsconfig.

注意:我已经对 tsconfig.json 文件进行了更改，并且还完成了 npm i @ types/node 和 npm i @ types/node--save 运行 npm 时，结果是 3个高安全性漏洞(请参见下文)

NOTE: I have already made changes to the tsconfig.json file and have also done npm i @types/node and npm i @types/node --save When running npm result was 3 high-security vulnerabilities (see below)

这时我该怎么办?`

customer.api.service.ts

   getCustomers(): Observable<Customers[]> {
        return this.httpclient.get<Customers[]>(this._url)
        .pipe( catchError(this.handleError));
        
    } 

    handleError(error:HttpErrorResponse){
        let rval = Math.random().toString(36).substring(7).toUpperCase();
        require('log-timestamp');
        console.error('MSG NO :' + rval );
        console.error(error);
        return throwError(rval + " <-> " + error.name + " <-> " + error.statusText );
     } 

ETA 我在这里找到了消息升级到Angular4后找不到名称"require" 并更改了我的 tsconfig.app.json 文件-可能过大了，但效果很好...

ETA I found the message here Cannot find name 'require' after upgrading to Angular4 and made the change to my tsconfig.app.json file - it may be overkill, but it worked ...

  "compilerOptions": {
    "outDir": "./out-tsc/app",
    "types": [ "node" ],
    "typeRoots": [ "../node_modules/@types" ]
  },

推荐答案

请确保将类型放在tsconfig.app.json中，而不是tsconfig.json中.

Make sure you put the type in your tsconfig.app.json not your tsconfig.json

  "compilerOptions": {
    "module": "esNext",
    "types": ["node"]
  },

还要确保组件中的系统税看起来像这样

Also make sure your systax in your component look like this

const someLib = require("someLib"); // make sure the name is match with your package name

然后停止角度cli，然后再次运行

Then stop angular cli then run again
