Can't seem to build latest code

Can't seem to build the latest clone code using cargo build. Always getting below error in opentelemetry.

error: failed to run custom build command for `opentelemetry-otlp v0.10.0`

any idea?

It appears that something in OpenTelemetry's build dependencies is calling either cargo fmt or rustfmt (directly). The command seems to indicate that rustfmt doesn't exist on your machine. I would love to have a better error message around this or documentation, but I'm not sure where it's coming from precisely.

To unblock you though, does running the following command — and then trying a new build — fix this for you?

rustup component add rustfmt

@abernix thnx for pointing out the issue. after knowing the issue the debugging was much easier.
my problem seems to be that i installed rust using brew and it didn't seem to install components like rustup, rustfmt etc. I had to uninstall via brew and installed rust again via rustup.rs. Rebuilding the code works fine now. thanks.
