如何使用Node require()在包名称上设置默认/回退范围

// 设置环境变量
process.env.DEFAULT_PACKAGE_SCOPE = '@myscope';

// 在代码中使用
const myPackage = require(process.env.DEFAULT_PACKAGE_SCOPE + '/my-package');

function requireWithFallback(mainPackage, fallbackPackage) {
  try {
    return require(mainPackage);
  } catch (e) {
    console.warn(`Failed to load ${mainPackage}, trying fallback...`);
    return require(fallbackPackage);
  }
}

const myPackage = requireWithFallback('@myscope/my-package', '@fallbackscope/my-package');

// config.js
module.exports = {
  defaultScope: '@myscope',
  fallbackScope: '@fallbackscope'
};

// main.js
const config = require('./config');
const myPackage = require(config.defaultScope + '/my-package') || require(config.fallbackScope + '/my-package');
