IntelliJ IDEA 2025 安装使用教程及常见问题解决方案

如下图，巴适的很！

卸载 IDEA

首先，如果电脑上有安装老版本的 IDEA , 需要卸载掉，没有安装则不用管。

下载 IDEA 

访问 IDEA 官网： IDEA 2025.3.2 版本的安装包：

开始安装

安装步骤如下图所示 :

1. 双击 .exe 安装包开始安装 ；
2. 自定义 IDEA 的安装路径，这里我选择安装在了 E:/ 盘下，点击下一步按钮；
3. 勾选创建桌面快捷方式，点击下一步按钮；
4. 点击安装按钮；
5. 等待安装成功…；
6. 安装成功后，先不要勾选运行 IDEA, 直接点击完成按钮；

脚本

脚本工具download : https://pan.baidu.com/s/1Cb6Yl-rBxTSqdHs8wL7zWw

提取码：3jmy

4. 关注后回复 “idea2025” 获取解压密码

 

下载成功后，将它解压到一个英文路径中。

进入到 /scripts 文件夹下，有两个 install 前缀的脚本，如下图所示：

• install-all-users.vbs : Windows 系统，点击执行此脚本；

 

双击 install-all-user.vbs 脚本 。然后，点击弹框中的确定按钮，需要等待个 10s – 30s 时间。

提示 Done , 则表示执行成功。

双击桌面的 IDEA 快捷启动图标，来打开 IDEA 。不要指定区域！！

如下图提示操作：

勾选 Activation code ，复制下面的码，输入后，点击 Activate 基本都能成功, 提示 Key is invalid, 重启一下电脑再试试：
