Something similar here on launch vscode. The error is coming from templ-vscode extension.

@bbaulenas - the log you posted show that you're running templ v0.2.707, not v0.2.747. The issue was fixed in https://github.com/a-h/templ/releases/tag/v0.2.731

[bbaulenas]

I'm sorry. That was my error. My go package github.com/a-h/templ/cmd/templ was older than my package github.com/a-h/templ in the project.

Thank you!

@MukundSinghRajput - most of the time, when people report this, it's that they've installed templ on Windows, but are using WSL in VS Code, and haven't installed go, gopls and templ in their WSL virtual machine.

Is that the case here?

[MukundSinghRajput]

@a-h No i am using Ubuntu and all the tools are installed :(

[a-h]

I have a Ubuntu laptop, and it's working OK for me. I added a new feature this morning to help debug issues like this.

If you run this:

go install github.com/a-h/templ/cmd/templ@main
templ info

It should print out a few log lines. It checks the path for various things that templ needs. What do you get?

[MukundSinghRajput]

mukund@mukund:~$ templ info
usage: templ <command> [<args>...]

templ - build HTML UIs with Go

See docs at https://templ.guide

commands:
  generate   Generates Go code from templ files
  fmt        Formats templ files
  lsp        Starts a language server for templ files
  version    Prints the version

@a-h I am getting this on using templ info

[a-h]

In that case, either you forgot to run go install github.com/a-h/templ/cmd/templ@main first, the version of templ that's first in the path is an earlier version, or go install has used a cached version.

The install might be cached, so if you run go install github.com/a-h/templ/cmd/templ@a98204d0eda8c14c468ff90549733064d232c7b5 instead, it should install the specific commit that contains the templ info feature, and therefore print out the log lines.

(✓) os [ goos=linux goarch=amd64 ] (✓) go [ location=/usr/local/go/bin/go version=go version go1.22.5 linux/amd64 ] (✗) gopls [ location=/home/mukund/.local/bin version= message=failed to get gopls version: fork/exec /home/mukund/.local/bin: permission denied ] (✓) templ [ location=/usr/local/go/bin/templ version=v0.2.753 ] I built templ from source and getting this

[a-h]

Great!

It looks like templ can't run the gopls executable at /home/mukund/.local/bin/gopls. It's probably worth checking the ownership of the file, and that the file is marked as executable chmod +x /home/mukund/.local/bin/gopls.

If you run /home/mukund/.local/bin/gopls --version yourself, you should see the same problem that templ is getting.

[MukundSinghRajput]

Thanks it is fixed now.
