4 years ago I see you are getting this error message: network failure seems to have happened. Perhaps there was some network error, or crates.io was down while you were trying to run the example. When you run a Rust program that has certain dependencies for the first time, Rust downloads them from crates.io. My guess is that there was some network error the moment you tried. Can you please try again and let me know if the problem persists.

I learned the Husky example from the
https://alphaville.github.io/optimization-engine/docs/example_navigation_ros_codegen#run-the-example-code-generation-program.When I run create_open_solver.py, the program always building optimizer.

Exception: Rust build failed
how should i solve this problem? Rust, clang, opengen, matplotlib are be installed sucessfully.
