敬启者：
我正在尝试使用 .lbx 文件作为参考文献的自有语言支持。该文件已位于 C:\texlive\2019\texmf-dist\tex\latex\biblatex\lbx，名为“basque.lbx”。目前，babel 包支持巴斯克语。
我创建了以下 MWE：
\documentclass[12pt]{article}
\usepackage[basque]{babel}
\usepackage[sorting=none, style=numeric-comp]{biblatex}{biblatex}
\addbibresource{bibliografia.bib}
\begin{document}
\cite{1868VonHelmholtz,1871Thomson,1883Reynolds,1894Reynolds,1922Richardson,1931Tollmien}
{
\let \clearpage \relax
\printbibheading
\printbibliography[heading=subbibliography, type=book, title={Liburu zein monografiak}]
\printbibliography[heading=subbibliography, type=article, title={Aldizkari artikuluak}]
\printbibliography[heading=subbibliography, type=report, title={Txosten teknikoak}]
}
\end{document}
“bibliografia.bib”文件为：
@article{1868VonHelmholtz,
author = {von Helmholtz, H.},
journal = {Philosophical Magazine},
number = {244},
pages = {337--346},
title = {{On Discontinuous Movements of Fluids}},
volume = {36},
year = {1868}
}
@article{1871Thomson,
author = {Thomson, William},
journal = {Philosophical Magazine},
pages = {362--377},
title = {{Hydrokinetic Solutions and Observations}},
volume = {42},
year = {1871}
}
@article{1883Reynolds,
author = {Reynolds, Osborne F. R. S.},
journal = {Royal Society of London},
pages = {84--99},
title = {{An experimental investigation of the circumstances which determine whether the motion of water shall be direct or sinuous, and of the law of resistance in parallel channels}},
volume = {35},
year = {1883}
}
@article{1894Reynolds,
author = {Reynolds, Osborne},
journal = {Proceedings of the Royal Society of London},
number = {336-339},
pages = {123--164},
title = {{On the dynamical theory of incompressible viscous fluid and the determination of the criterion}},
volume = {56},
year = {1894}
}
@book{1922Richardson,
author = {Richardson, Lewis Fry and Lynch, Peter},
edition = {1},
publisher = {Cambridge University Press},
title = {{Weather Prediction by Numerical Process}},
year = {1922}
}
@techreport{1931Tollmien,
address = {Washington},
author = {Tollmien, W.},
booktitle = {Technical Memorandum, 609},
institution = {National Advisory Committe for Aeronautics (NACA)},
pages = {1--35},
title = {{The Production of Turbulence}},
year = {1931}
}
但是，编译过程似乎没有找到前面提到的“basque.lbx”文件。事实上，日志文件提供了以下消息：
Package biblatex Info: Trying to load language 'basque'...
Package biblatex Info: ... file 'basque.lbx' not found.
Package biblatex Warning: Language 'basque' not supported.
(biblatex) Using fallback language 'english' on input line 7.
并加载英语语言文件。关于如何解决这个问题有什么想法吗？我已经尝试了以下帖子中发布的解决方案：biblatex 忽略自己的 lbx 文件。但情况稍有不同，一个\DeclareLanguageMapping命令并不能解决问题。
