这对我来说很管用:

把它放在dev和prod环境文件下。

environment.ts

declare const require: any;

export const environment = {
 appVersion: require('../../package.json').version,
};

任何组件的示例用法:

import { environment } from 'src/environments/environment';

     constructor() {
        console.log(environment.appVersion);
      }

在Angular 12中，从'../../package.json'导入{version};给出一个错误:

. / src /环境/环境。ts:10:13-20 -错误:不应该从默认导出模块导入命名的导出'version'(作为'version'导入)(只有默认导出可用)

继续导入版本，而不会带来包的全部内容的安全隐患。Json到构建中，你可以做:

export const environment = {
  ...
  VERSION: require('../../package.json').version,
};

如果遇到无法找到名称“要求”错误，请参阅https://stackoverflow.com/a/43129815/418819和https://stackoverflow.com/a/54004979/418819

为angular cli用户提供简单的解决方案。

添加声明模块'*.json';在src / typings.d.ts

然后在src/environments/environment.ts上:

import * as npm from '../../package.json';

export const environment = {
  version: npm.version
};

:完成)

这个https://github.com/angular/angular-cli/issues/5190有一个有趣的解决方案，使用shell文件来生成版本。ts文件。@sanjeev在这个论坛上有一个类似的解决方案。

这个解决方案使用Node, javascript和fs模块来实现相同的功能。在linux中工作是肯定的。在Windows中应该工作正常，因为Node/fs是跨平台的…对吧?

add a line to package.json: { "version": "0.0.1", ... "scripts": { "version": "node gen_version.js $npm_package_version", ... }, ... } create gen_version.js (note: it's not typescript) var fs = require('fs'); // arg[0]: node path // arg[1]: this script's path // arg[2]: 1st arg on command line console.log('current version: ' + process.argv[2]) path = 'src/environments/version.ts' script = 'export class Constants {' script += ' static readonly version = \'' + process.argv[2] + '\'' script += '}' fs.writeFile(path, script, function (err, file) { if (err) throw err; console.log('file saved:', path); }); Run it from npm: npm run version > omnitool@0.0.1 version ... > node gen_version.js $npm_package_version current version: 0.0.1 file saved: src/environments/version.ts use from your app: import {Constants} from "../environments/version" ... console.log('Version:', Constants.version)

打印稿

import { Component, OnInit } from '@angular/core';
declare var require: any;

@Component({
  selector: 'app-version',
  templateUrl: './version.component.html',
  styleUrls: ['./version.component.scss']
})
export class VersionComponent implements OnInit {
  version: string = require( '../../../../package.json').version;

  constructor() {}

  ngOnInit() {

  }
}

HTML

<div class="row">
    <p class="version">{{'general.version' | translate}}: {{version}}</p>
</div>

尝试DyslexicDcuk的答案，结果是找不到name require

然后，阅读https://www.typescriptlang.org/docs/handbook/modules.html中的“可选模块加载和其他高级加载场景”部分帮助我解决了这个问题。(Gary在这里提到了https://stackoverflow.com/a/41767479/7047595)

使用下面的声明来要求package.json。

declare function require(moduleName: string): any;

const {version : appVersion} = require('path-to-package.json');
