this weird cause i've been playing rails days, how uninstalled self?

this started happening since exited out of terminal , re-opened it. i'm lost , new rails have no thought of means, trying follow tutorial. thanks!

you trying install software scheme installation of ruby, set there apple.

rvm or rbenv install things private sandbox in home directory. error shows file isn't going there, rvm or rbenv isn't initialized correctly.

if run rvm, execute rvm info command-line, , @ info output, sanity check.
