vscoder-server无法离线安装插件

问题：用vscode在远程服务器上离线安装vsix插件时，显示Unable to connect to VS Code server: Error in request.

(py37) [jyh@*]$ code --install-extension workspace/GrapeCity.gc-excelviewer-4.2.59.vsix 
Unable to connect to VS Code server: Error in request.
Error: connect ENOENT /run/user/1013/vscode-ipc-b4d67f3e-a9c0-4052-8e90-abb4a64d2754.sock
    at PipeConnectWrap.afterConnect [as oncomplete] (node:net:1495:16) {
  errno: -2,
  code: 'ENOENT',
  syscall: 'connect',
  address: '/run/user/1013/vscode-ipc-b4d67f3e-a9c0-4052-8e90-abb4a64d2754.sock'
}

原因：错误消息中的 IPC（Inter-Process Communication）路径可能不再有效。这可能是因为服务器端已关闭或其IPC文件已被移动、删除或因权限问题而无法访问。查看相应目录下的文件，发现确实找不到对应的.sock文件

解决办法：将环境变量VSCODE_IPC_HOOK_CLI设为任意存在的.sock文件路径。再通过命令行安装插件即可。
