XeLaTeX cannot compile

\documentclass{article}
\usepackage{academicons}
\begin{document}
\aiOrcid
\end{document}

under my environment, frozen TeX Live 2017:

• XeLaTeX Version 3.14159265-2.6-0.99998 (TeX Live 2017)
• academicons 2017/05/15 v1.8.0
• fontspec 2017/11/09 v2.6g

while LuaLaTeX Version 1.0.4 (TeX Live 2017) can.

The error messages are

This patch solves the error.

@e-kwsm the error reads The font "academicons" cannot be found.. Have you installed the Academicons font on your system? Please read the package instructions before using it.

@diogo-fernan

Have you installed the Academicons font on your system?

Yes.

$ tlmgr info --list academicons 2> /dev/null | tail -n9
Included files, by type:
run files:
  texmf-dist/fonts/truetype/public/academicons/academicons.ttf
  texmf-dist/tex/latex/academicons/academicons.sty
doc files:
  texmf-dist/doc/fonts/academicons/README details="Readme"
  texmf-dist/doc/fonts/academicons/academicons.pdf details="Package documentation"
  texmf-dist/doc/fonts/academicons/academicons.tex

Only LuaLaTeX can find the bundled font, as documented in fontspec:

• fontspec-doc-fontsel.tex#L67

  In \LuaTeX, fonts found in the \textsc{texmf} tree can also be loaded by name.

• fontspec-doc-fontsel.tex#L97-L102

  \XeTeX\ and \LuaTeX\ also allow fonts to be loaded by file name instead of font name.
  When you have a very large collection of fonts, you will sometimes not
  wish to have them all installed in your system's font directories.
  In this case, it is more convenient to load them from a different location on your disk.
  This technique is also necessary in \XeTeX\ when loading OpenType fonts that are present within your \TeX\ distribution, such as \path{/usr/local/texlive/2013/texmf-dist/fonts/opentype/public}.
  Fonts in such locations are visible to \XeTeX\ but cannot be loaded by font name, only file name; \LuaTeX\ does not have this restriction.

  (Emphasis added)

Or, you mean we have to manually do something like cp /usr/local/texlive/2017/texmf-dist/fonts/truetype/public/academicons/academicons.ttf /usr/local/share/fonts/truetype/academicons?
I don't think it's a good idea.

[diogo-fernan]

The packages requires the font to be installed on the system, as per the documentation, where it is visible to all programs, not just TeX.

[e-kwsm]

The packages requires the font to be installed on the system

The design is not good.
This patch simplifies installation and maintenance. I was confused the situation where LuaLaTeX worked but XeLaTeX didn't though academicons was installed by tlmgr.
Why not?
Those who wants to use academicons for other softwares can install it on a system by themselves.

Implemented the suggestion in 8fe8286 and uploaded a new version to CTAN, which should be synchronized across repositories during the next day.

Thanks. :)
