Node 18+中Jest+jsdom环境下vm.runInContext无法访问window对象

开发项目时通过vm.runInContext加载测试所需的所有公共文件，该逻辑在Node 16中运行正常，但在Node 18及以上版本（如Node 20）中尝试访问window对象时，抛出"window is not defined"错误。

}

Jest配置文件 #

const config = {
testEnvironment: 'jsdom',
setupFilesAfterEnv: [ "<rootDir>/jestSetup.js"],
testMatch: ["<rootDir>/test/__test__/mytest.test.js"],
};

jest初始化文件（jestSetup.js） #

const vm = require('node:vm');
const fs = require( "fs" );

const ctx = vm.createContext(global);
ctx.hello = "helloworld";
ctx.window = "window";
const sContents = 'var a =1'


try {
  const result = vm.runInContext(`${sContents}; console.log(hello); console.log(window) `, ctx);
} catch(e) {
  console.log(e.stack, 'err1');
  console.log('x is', ctx.x)
}

  
module.exports = config;

Node 20中运行错误信息 #

evalmachine.<anonymous>:12
    ; console.log(hello); console.log(window) 
                                      ^
    ReferenceError: window is not defined
