I tried to follow the instructions from official github to install.
but still can't make sourcekit-lsp work in my vscode on ubuntu.

Can someone teach me how to install it on ubuntu18.04?
thanks

At which step does it break? Do you get any error messages?

using this command:
swift build -Xcxx -I~/swift5/usr/lib/swift

the error message i got:

Could you try using absolute path for Xcxx instead of the one starting with ~? I got burned by it when I tried to install sourcekit-lsp

Could you try installing libncurses5-dev and libncurses5 and try again? It helped when I tried to install sourcekit-lsp on 18.10 (Using sourcekit-lsp on Ubuntu 18.10)
