Font TeX Gyre Termes Unable to Use

Question

I am using the newest editions of MacOS, MacTeX, TeXMaker, and all the packages that I am using.

This is the code I have:

\documentclass[12pt, letterpaper]{article}
\usepackage{fullpage}

\usepackage{tex-gyre}
\usepackage{fontspec}
\setmainfont{TeX Gyre Termes}

\usepackage[doublespacing]{setspace}
\usepackage[backend=biber,
style=authoryear]{biblatex}
\addbibresource{SiouanAdpositions.bib}

\title{Blah Blah Blah}
\author{Noah Blah Blah\\[.4cm]{Supervisory Professor: Dr. Blah Blah}}
\date{October 5th, 2020}

\usepackage{graphicx}
\graphicspath{ {./images/} }

\usepackage{float}

\usepackage[nottoc,numbib]{tocbibind}

\usepackage{forest}

\usepackage{multicol}
\usepackage[mcolblock]{leipzig}
\makeglossaries

\begin{document}
asdf
\end{document}

I have also tried not using \usepackage{tex-gyre} I have tried manually downloading the font and putting it in the local tex folder, etc.

This is the error it gives me when I do include \usepackage{tex-gyre}:

! LaTeX Error: File `tex-gyre.sty' not found.

When I try installing this:

However, it seems the package is definitely loaded:

This is the error it gives me when I do not include \usepackage{tex-gyre}:

! Package fontspec Error: The font "TeX Gyre Termes" cannot be found.

Thank you so much for your time and help!

EDIT: I also tried adding \usepackage{tg-termes} which resulted in:

! Package fontspec Error: The font "TeX Gyre Termes" cannot be found.

Result of running those two commands:

To preemptively fix the problems you’ll get if you try \setmainfont{texgyretermes-regular.otf}, here is the recommended way to load the font:

\setmainfont{texgyretermes}[
  UprightFont = *-regular ,
  BoldFont = *-bold ,
  ItalicFont = *-italic ,
  BoldItalicFont = *-bolditalic ,
  Extension = .otf ,
  Scale = 1.0 ]

This tells fontspec what filenames to search for. If the italic font were named something like texgyretermes-mediumitalic.ttf, you would instead write ItalicFont = *-mediumitalic , Extension = .ttf.

I don’t have MacTeX to test on. On another OS, I would tell you to first reinstall the package with

sudo tlmgr update --self --all
sudo tlmgr install --reinstall tex-gyre

Then rebuild the font caches XeTeX and LuaTeX use with

sudo fc-cache -f -s -v
sudo luaotfload-tool -f -u -p -v

If you have some out-of-date files in the TeX Live subdirectory of your user folder, maybe clear those out.

Another solution would be to run sudo nano ${kpsewhich --var-value=TEXMFLOCAL}/fonts/TeXGyreTermes.fontspec to create a configuration file in your local TeX tree, and edit it to have the following contents:

\defaultfontfeatures[TeXGyreTermes]{
  UprightFont = texgyretermes-regular.otf ,
  BoldFont = texgyretermes-bold.otf ,
  ItalicFont = texgyretermes-italic.otf ,
  BoldItalicFont = texgyretermes-bolditalic.otf ,
  Ligatures = Common
}

This should enable commands like \setmainfont{TeXGyreTermes} even if your installation is not able to look up the font by its display name.

@DavidCarlisle and @Davislor answered the question in the comments.

What eventually worked for me was completely updated the entire TeXLive Manager, reinstalling TeX Gyre Termes, and then, instead of using \setmainfont{TeX Gyre Termes}, I used \setmainfont{texgyretermes-regular.otf}.

Thank you everyone for your help!!!
