xshell打开的ssh会话中，markdown实时预览如何生效？

[yxs]

vimplus安装完成之后，使用vim打开*.md文件并没有出现一个预览窗口。

@yexuesong 你好,markdown实时预览需要有界面的操作系统,你xshell访问的是server版本的linux吗?

[yxs]

@chxuan 嗯，有道理，应该装个gnome，还需要配置X11吗？还是说只要图形组件。

另外，我现在clean掉了一些不想要的插件，导致了报这个错？之前YCM都是正常可工作了的。
The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). YCM core library too old; PLEASE RECOMPILE by running the install.py script. See the documentation for more details.

为什么会导致这种情况？

跑了次install.py ，这个提示的log没有找到。
