Problem

You want to install rbenv, but when you are trying to clone the code with:

git clone https://github.com/rbenv/rbenv.git ~/.rbenv

you get the following error:

fatal: unable to access 'https://github.com/rbenv/rbenv.git/': SSL received a record that exceeded the maximum permissible length.

Solution

If you are behind a proxy server make sure that you add your proxy server details in your ~/.bash_profile and source the file afterwards.

So first add the details of your proxy like:

export http_proxy=http://xxx.xxx.xxx.xxx:8080
export https_proxy=https://xxx.xxx.xxx.xxx:8080

And finally source the file before running the installation again:

source ~/.bash_profile
