Hmm, something may have gotten messed up in your VM @fengkeven. Those are the files for logging your bash commands. I want to say that they don’t exist, and that’s why you’re seeing those messages - but I’m not sure. I feel like this won’t work, but you could try exiting the terminal and opening a new one. Don’t exit it with the x - type exit into it or use the trash can icon at the top right of the terminal.
If you’re not too far into it, you can start over using the instructions here. You may need to end up going that route.
Curious, if you type ls -a in the terminal, what do you see?
