除非代码在async function或模块中，否则不能使用await。您可以做的是：

const readline = require('node:readline/promises');
const rl = readline.createInterface({input: process.stdin, output: process.stdout});

async function main(){
    const answer = await rl.question('What is your favorite food? ');
    console.log(`Oh, so your favorite food is ${answer}`);
}

main();
