坑1

如果用Sublime编译时由于默认采用了pdfLatex进行编译，而fontspec宏包不是由其实现的，一般会出现


Fatal Package fontspec Error: The fontspec package requires either XeTeX or [\msg_fatal:nn {fontspec} {cannot-use-pdftex}]


解决办法

这个时候建议使用

xelatex

进行编译

xelatex o1.tex # 01.tex 为tex的源码

坑2

编译过程中可能报错其内容为可能带找不到字体的问题。具体内容可能如下：

(c:/texlive/2019/texmf-dist/tex/latex/ctex/fontset/ctex-fontset-windowsnew.def
kpathsea: Running mktextfm KaiTi/OT

The command name is C:\texlive\2019\bin\win32\mktextfm

kpathsea: Running mktexmf KaiTi/OT.mf

The command name is C:\texlive\2019\bin\win32\mktexmf
name = KaiTi/OT, rootname = KaiTi/OT, pointsize =
mktexmf: empty or non-existent rootfile!
Cannot find KaiTi/OT.mf.
kpathsea: Appending font creation commands to missfont.log.
kpathsea: Running mktextfm KaiTi/B/OT

其原因可能是相应的字体无法找到， 比如我电脑上的

楷体

的名字叫

楷体_GB2312

而非

KaiTi


解决办法

将文件

tex/latex/ctex/fontset/ctex-fontset-windowsnew.def

中的内容

\setCJKmainfont
          [ BoldFont = SimHei , ItalicFont = KaiTi] { SimSun }
        \setCJKsansfont
          [ BoldFont = { *~Bold } ] { Microsoft~YaHei }
        \setCJKmonofont { FangSong }
        \setCJKfamilyfont { zhkai } { KaiTi }

修改为：

\setCJKmainfont
          [ BoldFont = SimHei , ItalicFont = 楷体_GB2312 ] { SimSun }
        \setCJKsansfont
          [ BoldFont = { *~Bold } ] { Microsoft~YaHei }
        \setCJKmonofont { FangSong }
        \setCJKfamilyfont { zhkai } { 楷体_GB2312 }

最后再采用

xelatex

进行编译就可以编译通过了。

在我本机搜索到喊KaiTi字样的文件
