Which package do I have to install to fix this issue? Thanks.

Maybe you can refer this link sourcekit-lsp/Development.md at main · apple/sourcekit-lsp · GitHub

Linux

Install the following dependencies of SourceKit-LSP:

  • libsqlite3-dev, libncurses5-dev, python, ninja-build
$ export PATH="<path_to_swift_toolchain>/usr/bin:${PATH}" 
$ swift package update 
$ swift build -Xcxx -I<path_to_swift_toolchain>/usr/lib/swift -Xcxx -I<path_to_swift_toolchain>/usr/lib/swift/Block

@Zhao_Xin

Still the same.

I think you are missing

-Xcxx -I<path_to_swift_toolchain>/usr/lib/swift 

in addition to

-Xcxx -I<path_to_swift_toolchain>/usr/lib/swift/Blocks

which you specified.

Let me know if adding that option helped.
