CentOS rbenv update

1 minute read


Rbenv of CentOS seemed to be old, so update

First of all


rbenv update

Even if

> rbenv update
Updating rbenv
 |  fatal: unable to access 'https://github.com/sstephenson/rbenv.git/': SSL connect error
Updating rbenv-update

Get angry.



> cd ${rbenv root) #=> /usr/local/rbenv
> git remote add origin [email protected]:sstephenson/rbenv.git
> git pull origin master

will do. What, how to use git normally. Then, the commands required for plugins will be installed. Then

> rbenv update

Updating rbenv-update

It seems that the update was successful.

However, the latest version of ruby was 2.7.0-preview2, which was the same.

Good grief.
