Hi there , I met this problem when try to deploy in Lesson 5 brownie Simple Storage

ValueError: Unable to expand environment variable in host setting: 'https://rinkeby.infura.io/v3/$WEB3_INFURA_PROJECT_ID'

I think the cause is from infura setting ,but don't know where go wrong.also I found out infura change project ID to API key,but in .env file I still typed " export WEB3_INFURA_PROJECT_ID "

Hello @michaelclubman515

Please remember to add: dotenv: .en on your brownie-config.yaml. Additionally you can just copy and paste the export commands to the terminal and execute then before running the code.
