I believed that I successfully installed Ruby and RedisDump, however, when I run redis-dump or redis-load, terminal just told me "command not found". I don't know how to solve this problem.
The point is I had problem on installation of Ruby and Redisdump before, but I just tried a lot fixing suggestions online, and luckily solved the problem, I believed. So I don't know if I truly properly installed Ruby and RedisDump, or is this just another problem I need to solve?
To be honest, I am very new to this coding world but I am here to learn, thank you guys!
