Julia +Pumas@2.7.0 installation error: UndefVarError: `project_resolve_hash` not defined in `Pkg.Types`

Hi @Limei,

Glad you resolved it. The underlying issue is a change in APIs in Julia 1.12 which is what that stack trace says you were running the installer from. By manually adding Julia 1.11.6 you allowed the installer to run with an earlier Julia version that has the older APIs available.

For others finding this: There will be a fix made later today to resolve the issue without needing the workaround you’ve listed above.
