"Failed to check for clangd update: TypeError: Invalid comparator: Features:" error when running "clangd: Check for language server update"

[HighCommander4]

When I try to run the command "clangd: Check for language server update", I get the following error in a popup:

Failed to check for clangd update: TypeError: Invalid comparator: Features:

The stack trace in the devtools console (not that it seems very helpful) is:

The call that's throwing is this rangeGreater(releasedVer, installedVer) call.

Going into it, we have:

> releasedVer.raw
'15.0.1'
> installedVer.raw
'16.0.0
Features:'

I'm guessing that Features: shouldn't be there?

While debugging this, I discovered that vscode-clangd is not picking up the latest code in node-clangd -- rather, it is picking up the latest node-clangd release, 0.1.4, which does not contain some fixes such as this one, which may fix this (as well as #384).

Filed clangd/node-clangd#18 to release a new version of node-clangd so vscode-clangd can pick up the fixes.

[HighCommander4]

I figured out how to get vscode-clangd to consume the latest node-clangd locally, and confirmed that this bug still exists with the latest node-clangd.

Proposed fix at clangd/node-clangd#21
