Could not find a valid tsserver version

[ghostbuster91]

Hi,

I am trying to setup neovim with typescript language support through lsp. I use nix.
I already saw #336 and #28

I tried multiple things but whatever I do I always get the same error message:

RPC[Error] code_name = InternalError, message = "Request initialize failed with message: Could not find a valid tsserver version. Exiting."

I even provided explicitly path to the tsserver:

    require("lspconfig")["tsserver"].setup({
                on_attach = on_attach,
                capabilities = capabilities,
                cmd = { 
          "/nix/store/mis3pr62zjli08kdxg6lqhvkjbiih7kq-typescript-language-server-0.9.6/bin/typescript-language-server",
          "--stdio",
          "--tsserver-path",
          "/nix/store/cq9s34idhmcwqiy4jb89ghlpr6x6wiz1-typescript-4.5.5/lib/" }
    })

Calling typescript-language-server explicitly with above parameters doesn't yield any errors.

/nix/store/mis3pr62zjli08kdxg6lqhvkjbiih7kq-typescript-language-server-0.9.6/bin/typescript-language-server \
--stdio \
--tsserver-path /nix/store/cq9s34idhmcwqiy4jb89ghlpr6x6wiz1-typescript-4.5.5/lib/ \
--log-level 4 \
--tsserver-log-file=ts-logs.txt --tsserver-log-verbosity=verbose

I wish the error message was a little bit more descriptive.

Did it find tsserver at all? If so, why was it considered as invalid?

Could someone point me to a direction how can I debug that further?

Thanks in advance!

Running from the terminal doesn't reproduce because the discovery of typescript is only triggered after the LSP initialize message was received which doesn't happen when running manually like that.

I guess there could be some extra verbose log messages added to debug cases like that.

I've added additional logs that will be visible with --log-level 3 or higher that should make it is easy to debug this issue.

Thanks that was really fast, I will try with the newest version and let you know what I find.

@ghostbuster91 I ran into the same problem. You should have been targeting lib a few more levels down:

/nix/store/cq9s34idhmcwqiy4jb89ghlpr6x6wiz1-typescript-4.5.5/lib/node_modules/typescript/lib/

@carbonizer Thanks a lot! It worked like a charm :)

I get permission denied on this? any idea: Spawning language server with cmd: /nix/store/v4lcvq8ymzgyzc5iinpp 3lc5lvvgrl36-typescript-language-server-2.1.0/lib/node_modules/type script-language-server/lib/ failed with error message: EACCES: per

Check the path. It looks kinda broken to me (there is a space in one place and also not sure about the directory structure):

/nix/store/v4lcvq8ymzgyzc5iinpp 3lc5lvvgrl36-typescript-language-server-2.1.0/lib/node_modules/type script-language-server/lib/
