Electron/Angular 应用程序无法编译，因为缺少 http 模块

Question

I need to work on an Electron/Angular application that was already previously developed, I am just trying to add a feature. The app has not been touched for a while, but now when I try to launch it in development with

ng serve

I get the following error

Your global Angular CLI version (8.3.23) is greater than your local
version (6.0.8). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

in my /config/ directory I do not have a http or http.dev directory, I only have http.template.js file that contains this.

module.exports = {
    authUrl: "",
    apiUrl: "",
    logUrl: ""
};

Here is my environment.ts file

// This file can be replaced during build by using the `fileReplacements` array.
// `ng build ---prod` replaces `environment.ts` with `environment.prod.ts`.
// The list of file replacements can be found in `angular.json`.

import * as http from "../../config/http";
import * as devhttp from "../../config/http.dev";

Object.assign(http, devhttp);

export const environment = {
    production: false,
    http: http
};

                }
            }
        }
    },

}

I do not have a lot of knowledge about this application, so any help would be much appreciated. I just want to get it in a development setting so that I can work on it.

Answer 1

Sounds like the files are missing. Comment out the imports. Next try to figure out the value of http. It could be a boolean but most likely it's an key/value object.

//import * as http from "../../config/http";
//import * as devhttp from "../../config/http.dev";

//Object.assign(http, devhttp);

export const environment = {
    production: false,
    http: http
};
