We will use Ubuntu for our development environment. We can download the prerequisites using the following commands:
curl -O https://hyperledger.github.io/composer/latest/prereqs-ubuntu.sh
chmod u+x prereqs-ubuntu.sh
./prereqs-ubuntu.sh
It may prompt for your password, since it uses sudo during its execution.
