error: failed to determine package fingerprint for build script

[radhikabajaj123]

Hello Team,

I am getting

cd native && RUSTFLAGS="-Ctarget-cpu=native" cargo build --release
error: failed to determine package fingerprint for build script for datafusion-comet-proto v0.2.0 (/Users/radhika.bajaj/Documents/datafusion-comet/native/proto)
An I/O error happened. Please make sure you can access the file.

By default, if your project contains a build script, cargo scans all files in
it to determine whether a rebuild is needed. If you don't expect to access the 
file, specify `rerun-if-changed` in your build script.
See https://doc.rust-lang.org/cargo/reference/build-scripts.html#rerun-if-changed for more information.

when I run make release PROFILES="-Pspark-3.4 -Pscala-2.13" while following the instructions to Install DataFusion Comet.

I already have rust installed.

@radhikabajaj123 What happens if you run the following command from the terminal?

ls -l /Users/radhika.bajaj/Documents/datafusion-comet/native/proto

The issues seems to be with permissions to files in that folder?
