Install the Pre-requisites for Ubuntu

Use the following commands or follow the installing pre-requisites guide to prep the environment for Hyperledger Fabric installation.

curl -O https://gist.githubusercontent.com/skarlekar/6cab70ee0d8cecf60d66f9beabd40acf/raw/fb976b2986e2d2e59aa4ea8caf8f10016e85af41/prereqs-ubuntu.sh

chmod u+x prereqs-ubuntu.sh

Next run the script to install the pre-requisites.

./prereqs-ubuntu.sh

After the installation is complete you should see a message stating that the following components are installed:

1. node
2. npm
3. docker
4. python

At this point remember to log out and log back in to ensure you have access to the newly deployed binaries.

Verify that you have access to the binaries installed as follows:

docker -v
npm -v
node -v
python
