我正在学习 node.js,需要readline
用于一个项目。我直接从readline 模块示例中获得了以下代码。
const readline = require('readline');
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.question('What do you think of Node.js? ', (answer) => {
// TODO: Log the answer in a database
console.log('Thank you for your valuable feedback:', answer);
rl.close();
});
但是当我通过
node try.js
命令运行代码时,它不断给出如下错误:
rl.question('What is your favorite food?', (answer) => {
^^
