[tsserver 2304] [E] Cannot find name 'Deno'.

[Smithx10]

After installing Deno and configuring CoC neovim is showing errors that "[tsserver 2304] [E] Cannot find name 'Deno'."

Although completions are working.

Tested with same version of deno as you, can't reproduce.

[yaegassy]

@Smithx10 Do you have coc-deno installed? Or is it coc-denoland? In the case of coc-denoland, please report it to the coc-denoland issue.

---

As an additional note, for coc-denoland, you also need to set "tsserver.enable": false.

[Smithx10]

Any Ideas ?

I found this problem too, I fixed disabling of coc-tserver in current workspace because it was making conflict with it.

coc-tserver enabled and coc-deno enabled.

Doesn't find Deno Doesn't find top level await

coc-tserver not enabled and coc-deno enabled.

Finds Deno and suggest change "Denos" for "Deno" Finds top level await

[fannheyward]

I'm using coc-tsserver 1.6.8 and coc-deno 3.2.0, can't reproduce this issue, don't need to disable coc-tsserver.

Could you show your javascript configuration? I'm guessing that deno-ts is overriding tsserver in your environment or my configuration is prioritizing tsserver over deno-ts because when I disabled tsserver, deno-ts runs fine as you just show here.

@Classy-Bear I am having the same problem - did you find a resolution?

Not yet, meanwhile I have coc-tserver disabled because I don't use it anymore. I will investigate why this happens and let you know if I find something useful.

[maheshsundaram]

OK sure, thank you. I also disabled coc-tsserver as a workaround. At least it's simple to do.

Still can't reproduce this error.

console.log(Deno.args[0]);

.vim/coc-settings.json

{
  "deno.enable": true,
  "deno.lint": true,
  "deno.unstable": true
}

coc-deno 3.3.0 and coc-tsserver 1.7.0.

@Classy-Bear @maheshsundaram

Is there a minimum reproducible procedure?

This is the procedure I tried, coc-deno has no problem and is behaving correctly.

---

1. Preparation

mkdir -p /tmp/deno-check
cd /tmp/deno-check
nvim check.ts

The code is this one from the official manual. https://deno.land/manual@v1.9.0/getting_started/first_steps#making-an-http-request

2. Run:CocCommand deno.initializeWorkspace and checked and <CR>.

@Classy-Bear

If you really tried the same steps as I did (from creating the directory) and the problem persists, I don't know the cause of the problem either.

There seems to be nothing wrong with your various settings.

Try other machine environments using docker, vagrant, virtualbox, etc. and you may find the cause of your problem to be solved.

[Classy-Bear]

Yeah I will try that, thanks for your amazing help. Definitely is a problem with my environment, when I run :CocCommand deno.initializeWorkspace It flashes (The error goes away, it shows some warnings in the code and then the ts-server errors returns).

[Lite5h4dow]

im having the same issue and my imports arent working

[igorbrasileiro]

Is is possible to use coc-deno with another coc extension to show twind class suggestions that depends on coc-tsserver? I'm trying to port this extension https://github.com/tw-in-js/vscode-twind-intellisense/ that would depends on coc-tsserver like this one https://github.com/fannheyward/coc-styled-components/

[fannheyward]

@igorbrasileiro I don't think we can use these extensions with coc-deno or Deno LSP, cause typescript-styled-plugin etc plugins can only work as TypeScript plugins with tsconfig.json.
