How to install Root

Download the root file from https://root.cern/install/all_releases/

The binary root file is recommended for the local computer because it doesn't need to construct the specific environment in your local computer.

After finishing the download, you need to source the root in the terminal in order to use it in the terminal.

$ source pathname/root/bin/thisroot.sh

After the command, the root could be used in the terminal.

For the convenience, it is helpful to add a command in the .bash file.

In the linux OS,

$ vim .bash

In the mac OS,

$ vim .zshrc

Then add

source pathname/root/bin/thisroot.sh

in the bash file.

You can source the bash file to use root immediately or the computer do the things in bash file automatically after you restart your computer.
