Any solution? Deploying v2

It looks like the script is looking for the Uniswap V1 contract address on whichever network you are running on.
Do you have Uniswap V1 Factory deployed on that network, and is the Uniswap V1 Factory contract address listed in your installation_data.json file?

@Yudiz-Blockchain you must deploy the V1 first, I had the same problem
