我想使用该chemfig包并使用安装它本地管理器在 Arch Linux 中。然而，当我尝试pdflatex在 tex 文件上使用时像这个，

%Simplest working example example
%----------------------------------------------------------
Writting chemical formulae with chemfig is straightforward.
\chemfig{O=H}
%----------------------------------------------------------
\vspace{1cm}
%Angles between bonds
%----------------------------------------------------------
To define chemical formulae you can use units that define the angles
\chemfig{A-[1]B-[7]C}
Absolute angles
\chemfig{A-[:50]B-[:-25]C}
Relative angles
\chemfig{A-[::50]B-[::-25]C}
%----------------------------------------------------------
\vspace{1cm}
%Rings
%----------------------------------------------------------
Regular polygons
\chemfig{A*5(-B=C-D-E=)}
Incomplete rings are also possible
\chemfig{A*5(-B=C-D)}
%----------------------------------------------------------
\clearpage
%Branched molecule
%----------------------------------------------------------
Branched molecule \vspace{.5cm}
\chemfig{H-C(-[2]H)(-[6]H)-C(=[1]O)-[7]H}
%----------------------------------------------------------
\vspace{1cm}
%Branched ring
%----------------------------------------------------------
Branched ring
\vspace{.5cm}
\chemfig{A*6(-B=C(-CH_3)-D-E-F(=G)=)}

它给出了以下错误：

并且 pdf 输出很奇怪：
我是 latex 的新手，我主要在 Org-mode (emacs) 中使用它，我注意到当我使用 chemfig 时，它的 pdf 输出不正确，所以我决定pdflatex自己运行并看到这些错误。我有TeX 3.14159265 (TeX Live 2019/Arch Linux)
编辑：这是 pdflatex 的日志档案

那么请告诉我如何解决这个问题？
答案1
simplekv我使用更新了软件包tllocalmgr，虽然这解决了问题chemfig，但我仍然收到其他软件包的错误，因此我卸载了 Arch 的texlive安装，并使用了上游安装程序。这样做之后一切都完美无缺，甚至可以tlmgr正常工作。
所以答案是不使用发行版的包管理器。
