Below is quoted from the article
We recommend installing with npm when:
You aren't using a machine with amd64 or arm64.
You are installing code-server on Windows.
You're on Linux with glibc < v2.28 or glibcxx < v3.4.21.
You're running Alpine Linux or are using a non-glibc libc. See #1430 for more information.
Installing code-server with npm builds native modules on install.
This process requires C dependencies; see our guide on installing with npm for more information.
