python3 -m venv ROOTenv source ROOTenv/bin/activate

https://root.cern/install/#build-from-source

==` bash git clone –branch latest-stable –depth=1 https://github.com/root-project/root.git root_src mkdir root_build root_install && cd root_build #+BEGIN_SRC

Need to install cmake brew install cmake

#+END_SRC bash cat ~/setupROOT.sh cmake -DCMAKE_{INSTALLPREFIX}=../root_install ../root_src cmake –build . – install -j4 #+BEGIN_SRC

Then

source ../root_install/bin/thisroot.sh
