When I try to install and build the SUI binary on my local system with this command:

cargo install --git https://github.com/MystenLabs/sui.git --bin sui --branch devnet

I face this error:

Please specify a package, e.g. `cargo install --git https://github.com/MystenLabs/sui.git anemo-benchmark`.

After some digging, I found the solution and was able to install and build it error-free and completely using some modification in the above command:

For Devnet:

cargo install --locked --git https://github.com/MystenLabs/sui.git sui --branch devnet

For Testnet:

cargo install --locked --git https://github.com/MystenLabs/sui.git sui --branch devnet

This way, you can install and build SUI on your local machine and start on your way!

Best of luck.
