切换Docker到Podman后，VS Code Dev Containers扩展报错求助

从Docker切换到Podman构建镜像后，CLI环境下可正常构建运行容器，但使用VS Code的Dev Containers扩展连接容器时触发段错误，核心报错为Segmentation fault (core dumped)，同时伴随userEnvProbe is taking longer than 2 seconds. Process not found提示，完整错误日志如下：

解决方案 #

1. 调整userEnvProbe配置 #

段错误大概率和环境变量探测超时有关，在.devcontainer/devcontainer.json中强制指定探测类型或禁用探测：

// 方式1：使用loginShell探测
"userEnvProbe": "loginShell"

// 方式2：直接禁用探测（适合快速验证）
"userEnvProbe": "none"

2. 更新依赖版本 #

• 升级Podman到最新稳定版，修复Podman与VS Code扩展的兼容性问题
• 更新VS Code的Dev Containers扩展到最新版本，确保扩展支持Podman的最新特性

3. 清理VS Code远程服务器缓存 #

容器内的VS Code服务器文件可能损坏，执行以下命令清理后重新连接：

# 替换<container-name>为你的容器名称或ID
podman exec -it <container-name> rm -rf /root/.vscode-server

4. 检查容器内Node.js环境 #

VS Code服务器依赖特定版本的Node.js，若容器内Node版本不匹配可能触发段错误：

• 查看日志中VS Code服务器版本（如6c3e3dba23e8fadc360aed75ce363ba185c49794）对应的Node版本要求
• 在容器内安装匹配的Node.js版本
