Installation is failing with `error[E0277]: the trait bound `vergen::feature::build::Build: vergen_lib::entries::Add` is not satisfied`

This is on OpenSuse Tumbleweed using cargo from the OpenSuse repo: cargo 1.92.0 (344c4567c 2025-10-21) (built from a source tarball)

error: could not compile `openapi-tui` (build script) due to 1 previous error
warning: build failed, waiting for other jobs to finish...
error: failed to compile `openapi-tui v0.10.2`, intermediate artifacts can be found at `/tmp/cargo-install4pCOIY`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

I then tried using podman with the following command:

podman run --rm -ti -v $(pwd)/examples:/opt zaghaghi/openapi-tui -i /opt/petstore.json
openapi-tui error: Something went wrong
Error:
   0: Permission denied (os error 13)

So that did not work either.

Finally tried the binary download, and that worked.

Just logging these issues incase it is something important.

@nicc777, it works with the “--locked” argument.

@nicc777, it works with the “--locked” argument.

Thanks - I tried, but it just fails with another error:
