Dependency Conflict with prettyplease When Adding leptosfmt

[slanesuke]

Hey there

I'm just getting started with Leptos and following the directions from the Leptos Book for the first tutorial projects. I wanted to add leptosfmt to format my code, but I ran into a dependency conflict related to prettyplease. Not sure if I’m doing something wrong, but I keep getting this error:

cargo add leptosfmt                                                                                                               ─╯

    Updating crates.io index
error: failed to select a version for `prettyplease`.
    ... required by package `leptos_macro v0.7.7`
    ... which satisfies dependency `leptos_macro = "^0.7.7"` of package `leptos v0.7.7`
    ... which satisfies dependency `leptos = "^0.7.7"` of package `leptos-tutorial v0.1.0 (/Users/ianslane/Desktop/Rust_Portfolio/leptos-tutorial)`
versions that meet the requirements `^0.2.25` are: 0.2.30, 0.2.29, 0.2.28, 0.2.27, 0.2.26, 0.2.25

the package `prettyplease` links to the native library `prettyplease02`, but it conflicts with a previous package which links to `prettyplease02` as well:
package `leptosfmt-prettyplease v0.1.33`
    ... which satisfies dependency `leptosfmt-prettyplease = "^0.1.33"` of package `leptosfmt-formatter v0.1.33`
    ... which satisfies dependency `leptosfmt-formatter = "^0.1.33"` of package `leptosfmt v0.1.33`
    ... which satisfies dependency `leptosfmt = "^0.1.33"` of package `leptos-tutorial v0.1.0 (/Users/ianslane/Desktop/Rust_Portfolio/leptos-tutorial)`
Only one package in the dependency graph may specify the same links value. This helps ensure that only one copy of a native library is linked in the final binary. Try to adjust your dependencies so that only one package uses the `links = "prettyplease02"` value. For more information, see https://doc.rust-lang.org/cargo/reference/resolver.html#links.

failed to select a version for `prettyplease` which could resolve this conflict

I tried:

• Following the Leptos Book's setup
• Ran cargo update, but no luck
• Checked cargo tree -d, but it gives the same error
• Tried forcing a single prettyplease version using in Cargo.toml, but the conflict remains

Not sure if I’m missing something obvious, or if this is a bug. Any help would be appreciated! Thanks!

You shouldn’t add leptosfmt as a dependency but install it as a standalone executable by using cargo install instead of cargo add

Ah! Thank you.
