Build fails on fresh install

I'm new to Solana and struggling to find a single example repo that actually builds and works.

Build fails with

Error: `idl-build` feature is missing. To solve, add
[features]
idl-build = ["anchor-lang/idl-build"]
in `/path/to/CRUD-dApp/anchor/programs/journal/Cargo.toml`.
Warning: run-commands command "anchor build" exited with non-zero status code

 ——————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

 >  NX   Ran target anchor for project anchor (47s)

         With additional flags:
           build

    ✖    1/1 failed
    ✔    0/1 succeeded [0 read from cache]

Adding the idl-build = ["anchor-lang/idl-build"] line also fails with:

Error: IDL doesn't exist
Warning: run-commands command "anchor build" exited with non-zero status code

I downgraded to anchor 0.29.0 and it seems to build now.
