If you see “command not found,” don’t throw your laptop. You probably forgot to restart the terminal. Close it, open it again, and try. Computers are drama queens.
Another classic: permission errors. If you see “EACCES,” you’re basically a teenager asking for the car keys. Add sudo in front of commands to act like an adult. Or use nvm, which avoids this drama entirely.
Lastly, if nothing works, blame the moon. Developers do it all the time. Then post your error on Stack Overflow and wait for a stranger in Japan to solve it. The internet is magical.
