Issues while installing Hyperledger Composer

Question

I am trying to install Hyperledger on ubuntu, but after this command, it is showing error

mkdir ~/fabric-tools && cd ~/fabric-tools curl -O https://raw.githubusercontent.com/hyperledger/composer-tools/master/packages/fabric-dev-servers/fabric-dev-servers.zip unzip fabric-dev-servers.zip

Error as

FABRIC_VERSION is Unset

Answer 1

The mkdir (Make directory) and cd(Change Directory) Command is fine but you need to change your curl command as you have replaced the .tar.gz file with .zip and tar -xvf with unzip 

Try the following command which may help you to install Hyoerledger without errors

mkdir ~/fabric-dev-servers && cd ~/fabric-dev-servers

curl -O https://raw.githubusercontent.com/hyperledger/composer-tools/master/packages/fabric-dev-servers/fabric-dev-servers.tar.gz
tar -xvf fabric-dev-servers.tar.gz
