How can I get the \nameref command of the hyperref package to work while the enumitem package is loaded? The following gives an error while removing the enumitem fixes it.

\documentclass{article}

\usepackage{enumitem}
\usepackage{hyperref}

\begin{document}

\begin{description}
  \item [{Test\label{Test}}] Some text
\end{description}

\nameref{Test}

\end{document}

I tried to change the order of the packages but that does not help either.

Something like this should work. 

\documentclass{article}

\usepackage{enumitem}
\makeatletter
\newcommand\enit@descriptionlabel@hook[1]{}
\def\enit@description@i#1#2#3#4{%
  \ifnum#1>#3\relax
    \enit@toodeep
  \else
    \enit@list{}%
      {\let\enit@type\tw@
       \advance#1\@ne
       \labelwidth\z@
       \enit@align@left
       \let\makelabel\descriptionlabel
       \enit@style@standard
       \enit@preset{#2}{#1}{#4}%
       \enit@calcleft
       \let\enit@svlabel\makelabel
       \def\makelabel##1{%
         \NR@gettitle{##1}%
         \labelsep\z@
         \ifenit@boxdesc
           \enit@svlabel{\enit@align{\enit@format{\enit@descriptionlabel@hook{##1}}}}%
         \else
           \nobreak
           \enit@svlabel{\enit@format{\enit@descriptionlabel@hook{##1}}}%
           \aftergroup\enit@postlabel
         \fi}%
       \enit@before
       \enit@negwidth}%
     \enit@keyfirst
  \fi}

\usepackage{hyperref} 
\AtBeginDocument{\let\descriptionlabel\NRorg@descriptionlabel}
\renewcommand\enit@descriptionlabel@hook[1]{\NR@gettitle{#1}#1}
\begin{document}


\begin{description}
  \item [{Test}\label{Test}] Some text
\end{description}

\nameref{Test}

\end{document}

So to get it working enumitem must add a hook, and hyperref must then use it.

    Apparently it's not "the best we have" :) – Alan Munn Jul 17 '19 at 20:47

    @UlrikeFischer Thanks for checking. I get ! Undefined control sequence. <argument> ...el \fi }\enit@before \enit@negwidth l.42 \item [{Test}\label{Test}] Some text The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g., `\hobx'), type `I' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined. – Daniel Jul 18 '19 at 08:24

    Is your enumitem version up-to-date? – Ulrike Fischer Jul 18 '19 at 08:26
  • @UlrikeFischer Thanks. Updating my system did the trick! Any idea why the author of enumitem does not fix his package in this way? Or is there a downside? – Daniel Jul 18 '19 at 09:09

    I wrote to the enumitem maintainer. If he changes enumitem, I can adapt nameref to get it working directly. – Ulrike Fischer Jul 18 '19 at 09:11

This is a known issue with enumitem documented in section 12.2 of the documentation. The workaround suggested there is to let \makelabel to \descriptionlabel in the before code of the list, and that indeed seems to work, but as Ulrike points out in the comments, it's not really a complete solution.

\documentclass{article}

\usepackage{enumitem}
\usepackage{hyperref}

\begin{document}

\begin{description}[before=\let\makelabel\descriptionlabel]
  \item [{Test\label{Test}}] Some text
\end{description}

\nameref{Test}

\end{document}
