solana account <address>
When I get account info, I have this error:
Error: RPC request error: cluster version query failed: error sending request for url (http://localhost:8899/): error trying to connect: tcp connect error: Connection refused (os error 111)
The error is indicating that the CLI RpcClient can not communicate with the Solana validator.
This is usually caused by not having solana-test-validator
running in another terminal. Many make the mistake of thinking that the localhost is running the validator all the time... it's not.
In one terminal do: solana-test-validator
which will startup up the local validator
Open a second terminal and do solana account
- This will return account info for the default keypair
