什么？ 你还没用过 Cursor？ 智能 AI 代码生成工具 Cursor 安装和使用介绍

Cursor AI IDE 开发者工具

Cursor——ChatGPT的替代品

下载

官网下载Cursor

登录

点击设置
点击sign in

可以使用github账号登录

使用

先别打开任何文件，就可以回答问题了

如果回答的是英文，就它让用中文回答


它能回答，编程问题

如何回答，变成以外的问题，请看后面

可以发现，它默认的是python代码

新建一个文件 main,java

输入文件名，敲回车

编写区，Ctrl+L

就写出的是java代码了

怎么让它问答一个编程以外的问题

新建一个hello.txt文件
然后写一个编程之外的问题

测试有可能不成功
