如果我在orgmode 中插入一个heading，比如： * Hello,world 时,C-c C-e l l 导出的 LaTeX 文件中会自动生成一个 label,如：
\section{Hello,world}
\label{sec:org42786f1}
我在配置中已经将org-latex-prefer-user-labels设置为：
(setq org-latex-prefer-user-labels t)
如何禁止自动生成 label， 因为我想自己指定 label，如：
* Hello,again
\label{sec:hello-again}设置标题的 CUSTOM_ID , 快捷键 C-c C-x p
* Hello, again
:PROPERTIES:
:CUSTOM_ID: hello-again
:END:
设置了 CUSTOM_ID 属性之后，还是不行
* Hello,world
:PROPERTIES:
:CUSTOM_ID: hello-world
:END:
+ hello,one
+ hello,two
+ hello,three
生成的 LaTeX 为：
\section{Hello,world}
\label{sec:orga88409c}
\begin{itemize}
\item hello,one
\item hello,two
\item hello,three
\end{itemize}
Orgmode 版本：
Org mode version 9.1.13 (9.1.13-elpaplus @ /Users/tilabs/.emacs.d/elpa/org-plus-contrib-20180528/)
Emacs 版本：
GNU Emacs 25.3.1 (x86_64-apple-darwin17.5.0, NS appkit-1561.40 Version 10.13.4 (Build 17E199)) of 2018-04-14你检查下 org-latex-prefer-user-labels 是 t 么?
我用的版本:
GNU Emacs 26.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.22.30) of 2018-05-29
Org mode version 9.1.13 (9.1.13-elpaplus @ /home/yyj/.emacs.d/elpa/org-plus-contrib-20180528/)
org-latex-prefer-user-labels 文档里说这样做是标准方法:
When this variable is non-nil, Org will use the value of
CUSTOM_ID property, NAME keyword or Org target as the key for the
\label commands generated.
By default, Org generates its own internal labels during LaTeX
export. This process ensures that the \label keys are unique
and valid, but it means the keys are not available in advance of
the export process.
......
For example, when this variable is non-nil, a headline like this:
** Some section
:PROPERTIES:
:CUSTOM_ID: sec:foo
:END:
This is section [[#sec:foo]].
#+BEGIN_EXPORT latex
And this is still section \ref{sec:foo}.
#+END_EXPORT
will be exported to LaTeX as:
\subsection{Some section}
\label{sec:foo}
This is section \ref{sec:foo}.
And this is still section \ref{sec:foo}.
org-latex-prefer-user-labels 确定是 t, 我在vanilla emacs 下按你说的做的话，是working的。可能是我的配置有毛病，我在排查一下，谢谢!
这个配置是不是有问题啊？

我自己不用 use-package，所以不太熟悉，没看出问题在哪
检查一下你的 elpa 文件夹里是否有多个版本的 org，如果有的话删掉一个，比如 org-20180528xxxx，只留下 org-plus-contrib。可以先看一下命令 org-version 的输出，看看有没有什么问题。
