Issue upgrading from 0.3.1 to 0.4.x

[Neighborkid01]

Hello,

I have a project I haven't been able to work on in a while and am just getting back to it. I'm trying to upgrade from Leptos 0.3.1 to a later version (eventually 0.5.0).
I wanted to move to 0.4.x and fix any issues and then move from there to 0.5.
My current Cargo.toml and the version I'm migrating from are here

When I run cargo leptos build, I get the following error:

error[E0599]: no method named `line` found for struct `proc_macro::LineColumn` in the current scope
   --> /Users/razor_crest/.cargo/registry/src/index.crates.io-6f17d22bba15001f/leptos_macro-0.4.10/src/lib.rs:397:30
    |

    |                              |
    |                              field, not a method

For more information about this error, try `rustc --explain E0599`.

I've tried adding leptos_macro to my Cargo.toml so that I can explicitly set the version, but I still get the same error on other 0.4.x versions.

If I only update the Leptos version to 0.4 and don't update it to have features = ["nightly"], I get syntax errors for my components as expected, but as soon as I add the nightly feature to leptos, leptos_meta, or leptos_router, I get the error.

Any help would be appreciated as I'm not quite sure what dependency this issue actually stems from. I don't know if it's from leptos_macro or somehow in proc_macro, or if I need to pin a specific version of a dependency...

Thanks!

You should just need to rustup update nightly. There was a breaking change in this nightly API in about late July, which caused this issue until people updated Leptos version and nightly compiler.

Thank you!
