如何修复Node.js抛出er；//未处理的'error‘事件

try {
    // 可能抛出错误的代码
    throw new Error('Something went wrong!');
} catch (err) {
    console.error('Caught an error:', err);
}

const EventEmitter = require('events');
const myEmitter = new EventEmitter();

myEmitter.on('error', (err) => {
    console.error('Error occurred:', err);
});

// 触发错误事件
myEmitter.emit('error', new Error('An error happened!'));

process.on('uncaughtException', (err) => {
    console.error('Uncaught Exception:', err.message);
    process.exit(1); // 强制退出进程
});

async function fetchData() {
    try {
        const response = await fetch('https://api.example.com/data');
        const data = await response.json();
        return data;
    } catch (error) {
        console.error('Fetch error:', error);
    }
}
