我尝试使用国际环境政策研究所制作图表。我遇到了问题pdftex每次我尝试编写数学命令时，软件都会返回此错误，我在程序员网站上报告了此错误：otfried/ipe 问题
我尝试设置路径在 .bash_profile 中，但我没有任何结果。Ipe 不断返回错误。
这是我的 .bash_profile
#local bin path:
#LaTeX path:
export PATH=/usr/local/texlive/2018/bin/x86_64-darwin:$PATH
export PATH=$PATH:/Library/TeX/Distributions/.Defaults/TexLive-2018/Contents/Programs/texbin
#export PATH=/usr/local/texlive/2018/bin/x86_64-darwin/pdftex"$"PATH
有解決方案嗎？

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

答案1
这与您使用的操作系统或路径无关，因为 pdfTeX 正在根据链接的日志运行文件。
问题是您混合了文本和数学模式。
要插入内联数学，您可以：
第一个选项：使用“数学符号”按钮并写出等式没有周围环境$...$：
第二种选择：使用“文本标签”按钮并写下等式和周围环境$...$：
要插入显示数学，您必须使用“段落”按钮并像在 LaTeX 中一样书写：
