【C++Debug日记】Resolver error: Error: The VS Code Server failed to start，解决！！

今日正常启动vscode ssh准备编辑写写代码，结果无法连接到远端服务器，我用Xterm试了一下，发现远端服务器可以照常连接，故排除了服务器本身的连接问题；
具体报错信息如下：

可以看到报错信息：
Resolver error: Error: The VS Code Server failed to start
那么问题就肯定来源于VSCODE啦，故首先排除本地vscode上有问题（我用的挺正常的，连接其他服务器也都无问题），那么就是远端服务器问题啦。

故尝试以下步骤来解决：

1. ctrl-shift-p后选择
2. Remote-SSH:kill VS Code Server on Host...
3. 重新打开对应的远端服务器即可
