How to Create Virtual Environments in Spack: Isolating Software Environments Made Easy
As of my last update in September 2021, Spack does not natively provide a built-in virtual environment functionality similar to Python's virtualenv or Anaconda environments. However, you can achieve similar isolation and environment management using Spack's environments feature. Spack environments allow you to create isolated environments for specific sets of packages, similar to how virtual environments work. Here's how you can create a virtual environment-like environment using Spack: 1.
