I am trying to install buck2 on my ubuntu machine. These are the commands I ran (from buck2 site)
rustup install nightly-2023-05-28
cargo +nightly-2023-05-28 install --git https://github.com/facebook/buck2.git buck2
but I am getting this error
error: failed to run custom build command for `buck2_core v0.1.0 (/home/user/.cargo/git/checkouts/buck2-881d6af740402932/8eee9d4/app/buck2_core)`
