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');

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)

这个答案只针对Angular 12+。它使用Webpack 5。

根据webpack5文档

新规范不支持这一点，您将得到一个警告。而不是:

import { version } from './package.json';
console.log(version);

use:

import pkg from './package.json';
console.log(pkg.version);

另外，你必须在tsconfig.json中提供

"compilerOptions": {
  ...
  "allowSyntheticDefaultImports": true
  "resolveJsonModule":true
  ...

你可以看包装。Json就像任何其他文件一样，带有http。像这样:

import {Component, OnInit} from 'angular2/core';
import {Http} from 'angular2/http';

@Component({
    selector: 'version-selector',
    template: '<div>Version: {{version}}</div>'
})

export class VersionComponent implements OnInit {

    private version: string;

    constructor(private http: Http) { }

    ngOnInit() {
        this.http.get('./package.json')
            .map(res => res.json())
            .subscribe(data => this.version = data.version);
    }
}

如果你正在使用webpack或angular-cli(使用webpack)，你可以只需要package。Json，然后显示那个道具。

const { version: appVersion } = require('../../package.json')
// this loads package.json
// then you destructure that object and take out the 'version' property from it
// and finally with ': appVersion' you rename it to const appVersion

然后是分量

@Component({
  selector: 'stack-overflow',
  templateUrl: './stack-overflow.component.html'
})
export class StackOverflowComponent {
  public appVersion

  constructor() {
    this.appVersion = appVersion
  }
}
