I agree with Luna that installing from official GitHub Releases 
are the easiest way.
There is also this project: https://code.dlang.org/packages/ldcup

regarding serve-d - you need to download the code from the github 
and build it locally with the latest LDC compiler.
It should fix the issue.

Also don't forget to switch the version of the "code-d" extension 
to "beta/nightly". Stable is very old and not updating properly.
