日志核心问题一眼定位

报错关键文本：

WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
Host key for 192.168.5.20 has changed and you have requested strict checking.
Host key verification failed.

原因

之前连过旧IP/重装/换系统后的树莓派，本地 known_hosts 缓存了旧密钥，现在设备密钥变了，OpenSSH 安全校验直接拒绝连接，管道断开，VSCode连不上。

修复步骤（按顺序执行，1分钟解决）

1. 删除本地冲突主机密钥（必做）

方式A：PowerShell/CMD执行一键清除

ssh-keygen -R 192.168.5.20
ssh-keygen -R raspberrypi_3b

执行完成会提示：# Host 192.168.5.20 found: line 16，已删除冲突行。

方式B：手动删除文件

路径：C:\Users\Administrator\.ssh\known_hosts
用记事本打开，删掉包含 192.168.5.20 的整行，保存关闭。

2. 先手动SSH登录一次，确认信任新密钥

打开CMD/PowerShell执行：

ssh hxkj@192.168.5.20

会弹出提示：

Are you sure you want to continue connecting (yes/no/[fingerprint])?

输入 yes 回车，输入密码正常进入树莓派终端。

这一步是让系统写入新的合法密钥，VSCode后续连接不会拦截。

3. 清理树莓派端旧VSCode服务（可选但推荐）

手动ssh连上树莓派后执行：

rm -rf ~/.vscode-server
exit

4. 重启VSCode重新连接

完全关闭VSCode所有窗口再打开
左侧远程面板找到 raspberrypi_3b，点击重试连接

补充说明

日志里ssh路径检索正常，Windows自带OpenSSH C:\WINDOWS\System32\OpenSSH\ssh.exe 可用，不是ssh工具缺失问题；
过程试图写入的管道不存在 只是密钥校验失败后的连锁报错，根源只有主机密钥不匹配；
后续如果再次重装树莓派、修改IP，重复执行 ssh-keygen -R IP 即可。

兜底方案（上面操作无效时）

修改ssh配置关闭严格主机校验：

VSCode远程SSH面板 → 右上角齿轮 Open SSH Configuration File
选择 C:\Users\Administrator\.ssh\config
给我的 raspberrypi_3b 主机添加两行：

Host raspberrypi_3b
  HostName 192.168.5.20
  User hxkj
  StrictHostKeyChecking no
  UserKnownHostsFile /dev/null

保存后重启VSCode直接连接，不会再校验密钥。
