[SOLVED] update ruby in mac

update ruby in mac

I do not have RVM installed. I want to install ruby 2.5.1. When I install RVM with "rvm install ruby-2.5.1", I get the error: "-bash: rvm: command not found".

My default ruby version in my iMac is 2.3.3

When I run "ruby -v" I'm getting this,

ruby 2.3.3p222 (2016-11-21 revision 56859) [universal.x86_64-darwin17]

But the latest version is 2.5.1

When I try to install rvm it's getting this message.

NOTE: GPG version 2.1.17 have a bug which cause failures during fetching keys from remote server. Please downgrade or upgrade to newer version (if available) or use the second method described above.

I tried these to solve my problem URL's to solve, but no use.

Solution

Finally i updated successfully with the help of this link...

https://www.computersnyou.com/5307/setup-homebrew-and-rvm-on-mac-osx-10-11-ei-capitan/

I typed this command,

\curl -sSL https://get.rvm.io | bash -s stable

After that i used this command,

type rvm | head -n 1

It's printing "rvm is a function"

After that i used this command,

rvm install ruby-head

After some time RVM installed.

When i type this command

ruby -v

I'm getting this message "ruby 2.6.0dev (2018-05-16 trunk 63444) [x86_64-darwin17]"
