I'm trying to use orml-tokens in my Substrate project and encountered the following error:

    error[E0603]: module `group` is private
     --> /home/kianoush/.cargo/registry/src/github.com-1ecc6299db9ec823/frame-support-procedural-tools-3.0.0/src/syn_ext.rs:47:53
      |
  47  |                 let syn::group::$name { token, content } = syn::group::$parse(input)?;
      |                                                                 ^^^^^ private module

      | ^^^^^^^^^

      | ^^^^^^^^^

I'm using frame-support-procedural-tools v3.0.0 How can I resolve this issue? Are there any workarounds or specific dependency versions I should use to avoid this error?

Using rustc version: rustc 1.68.0-nightly (574b64a97 2022-12-31)

This looks like an issue with mistmached versions, what version of Susbtrate are you using in your project?

You can try to update Substrate if you are using an old version, and have the frame-support-procedural-tools v3.0.0 to the last one: see Cargo.toml.

Or update the library is failling manually with:

cargo update -p syn

See this old question on StackExchange: Substrate Node Template Build Error, syn::group private
