Youplot Installation on Ubuntu-24.04 to Plot Data in Terminal

You're using conda (likely via Anaconda or Miniconda), and you're aiming to install YouPlot using Ruby via gem. This method is useful if you want to keep everything isolated in a conda environment — great for avoiding system-wide changes.

Step 1: Create or activate a conda environment

This keeps Ruby and YouPlot isolated from your system.

$ conda create -n youplot-env
$ conda activate youplot-env

Step 2: Install Ruby from conda-forge

This installs the Ruby interpreter and RubyGems.

conda-forge provides up-to-date Ruby builds that are well-maintained.

$ conda install -c conda-forge ruby

Step 3: Install compilers (for native extensions)

Some Ruby gems require native code to be compiled during installation (C extensions).
youplot may need this to compile dependencies like ffi.

$ conda install -c conda-forge compilers

Step 4: Install YouPlot via RubyGems

This installs the uplot command.

gem is Ruby’s package manager, like pip for Python.

$ gem install youplot

Step 5: Test It

Once done, test:

$ uplot --help

If uplot is not found, try:

$ which uplot
