Does anyone know how to fix this? Very new to cardano please help.

cardano-node run --topology path/home/cardano/cardano-node/mainnet-topology.json --database-path /home/cardano/cardano-node --socket-path path/home/cardano/cardano-node --port 3000 --config /home/cardano/cardano-node/mainnet-config.json

using this to launch the node and getting this error

cardano-node: FatalError {fatalErrorMessage = “Cardano.Node.Run.readTopologyFile: Cardano.Node.Configuration.Topology.readTopologyFile: path/home/cardano/cardano-node/mainnet-topology.json: openBinaryFile: does not exist (No such file or directory)”}

Hello,

Try changing:

**–topology path/home/cardano/cardano-node/mainnet-topology.json**  
to  
**–topology /home/cardano/cardano-node/mainnet-topology.json**

and change

**–database-path /home/cardano/cardano-node**  
to  
**–database-path /home/cardano/cardano-node/db"**

and change

**–socket-path path/home/cardano/cardano-node**  
to  
**–socket-path /home/cardano/cardano-node/db/node.socket"**
