solana-lldb can not debug solana program?

[takanara1994]

I followed the tutorial of how to do "Source level debugging"(https://solana.com/docs/programs/debugging), but in solana-lldb step,after type file target/deploy/learn_solana.debug, it show that error: ~/Projects/learn_solana/target/deploy/learn_solana.debug' doesn't contain any 'host' platform architectures: x86_64, i386.Did I do something wrong?

Can you provide more details:

1. the machine, OS etc that you were debugging on?
2. The output of file ~/Projects/learn_solana/target/deploy/learn_solana.debug
