Unresolved Import Error with Yew Framework

[jinseok9338]

rust-analyzer version: (0.2.853)

rustc version: (rustc 1.61.0 (fe5b13d68 2022-05-18))

I have noticed that rust analyzer spit out an unresolved import error when importing function component in Yew framework.
When spinning up the yew project with trunk serve it works fine and rust is not complaining but the rust analyzer seems to be angry that you can't import function component

I have attached the picture

What does the theme module look like?

this is theme that I copied and tweaked but the structure is all the same
It's not just ThemeProvider. Rust-analyzer throws error when I import function component.
From above Rust-analyzer doesn't throw error when importing LandingPages. It's because LandingPages is a struct component, not a function component

[Veykril]

Does the #[styled_component(ThemeProvider)] properly expand in your theme module? You can check by clicking on it and then running the command Expand Macros Recursively accessible by pressing ctrl + shift + p

[jinseok9338]

No it does not... Can you tell me how to fix the problem??

[Veykril]

If proc-macros don't expand you either have them disabled in your settings or something else is failing when we run the build scripts most likely, can you check your Rust Analyzer Language Server Logs logs for errors?

this is the log

Hmm, that error is irrelevant unfortunately.

#10894

Thanks to your keen insight I was able to "what" the error was but unable to find the answer to the problem and upon looking up the problem, I am not the only one.

[Veykril]

Oh actually I just realized your rust-analyzer version, that one is very much outdated. I'd recommend trying to reinstall it assuming it stopped auto-updating itself.

[jinseok9338]

Thanks ... but since I am using gitpod. The one I am using is the most updated one... Thanks for your input. I am sure they will update the extension, but in the meantime ignoring the error message will do :)
