从 Org-mode 导出到 Beamer 时出错

tag-icon • tag-icon beamer emacs org-mode export
从 Org-mode 导出到 Beamer 时出错

当我尝试从 org 导出到 beamer 时，我收到以下消息：

处理 LaTeX 文件 ./ppt.tex... org-latex-compile：未生成 PDF 文件 ./ppt.pdf：[未定义的控制序列]

我不知道这是什么意思。有人能帮我理解并修复这个错误吗？也许我没有正确配置emacs适合这种出口吗？

这是我从 TeX.SX 中的一个问题中复制的文件的一部分.emacs。我不确定我是否配置了 AUCTeX，shell-escape但我希望.emacs在最终的 pdf（无论是文章还是 beamer 演示文稿）中包含一些 python 行时，文件中有正确的代码。

    ;; Org mode and bearmer export
(require 'ox-beamer)
(setq org-latex-to-pdf-process 
  '("pdflatex --shell-escape -interaction nonstopmode -output-directory %o %f"
"pdflatex --shell-escape -interaction nonstopmode -output-directory %o %f"
"pdflatex --shell-escape -interaction nonstopmode -output-directory %o %f"))


(defun my-beamer-bold (contents backend info)
 (when (eq backend 'beamer)
  (replace-regexp-in-string "\\`\\\\[A-Za-z0-9]+" "\\\\textbf" contents)))

(add-to-list 'org-export-filter-bold-functions 'my-beamer-bold)

(setq org-src-fontify-natively t)
(org-babel-do-load-languages
 'org-babel-load-languages
 '((python . t)
  (latex . t)))
(setq org-confirm-babel-evaluate nil)
(setq org-babel-python-command "ipython --pylab --pdb --nosep --classic --no-banner --no-confirm-exit")

(setq org-latex-listings 'minted)
(setq org-latex-minted-options
   '(("fontsize" "\\footnotesize")("bgcolor" "black")("obeytabs" "true")))

(require 'ox-latex)
(setq org-src-fontify-natively t)
(setq org-latex-pdf-process
   '("pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"
    "pdflatex -shell-escape -interaction nonstopmode -output-directory %o   %f"
    "pdflatex -shell-escape -interaction nonstopmode -output-directory %o %f"))
(setq org-src-preserve-indentation t)

以下是ppt.org我无法翻译成pdf的文件！

我已将您提供的代码添加到我的 emacs 设置中（可以在我的 github 上找到，抱歉进行了宣传），并使用 emacs 24.4.1 。

错误来自句子/what/, when, how。Beamer 不太喜欢使用\emph{}章节标题中使用的和其他命令。避免这种情况的一种方法是使用 LaTeX 命令：** \protect\emph{what}, when, how。

结果是：

目前我还没有找到仅使用 org 命令的解决方案，如果有人有的话，我很感兴趣。
