自上次更新graphics-def（2017-06-12）以来，我在使用auto-pst-pdf和时收到错误消息pstricks。这些错误消息涉及\stockwidth和长度，如果我没记错的话，stockheight它们是由类定义的，但我没有使用。在控制台中输入仍然会产生正确的pdf文件，但有6个错误，所以我想知道上次更新中是否存在错误。memoirs
这是一个产生错误的非常简单的代码：
\documentclass[border=3pt]{standalone}
\usepackage{pst-plot, auto-pst-pdf}%
\begin{document}
\begin{pspicture}
\psaxes[ticks=none, labels=none, arrows=->](0,0)(-3,-3)(3,3)[$x$,-135] [$y$,180]
\uput[dl](0,0){$ O $}
\end{pspicture}
\end{document}
以及 .log 文件的相关部分：
! Missing number, treated as zero.

\stockwidth
l.5 \begin{document}
? s
OK, entering \scrollmode...
! Illegal unit of measure (pt inserted).
<to be read again>
\stockwidth
l.5 \begin{document}
Dimensions can be in units of em, ex, in, pt, pc,
cm, mm, dd, cc, nd, nc, bp, or sp; but yours is a new one!
I'll assume that you meant to say pt, for printer's points.
To recover gracefully from this error, it's best to
delete the erroneous units; e.g., type `2' to delete
two letters. (See Chapter 27 of The TeXbook.)
! Undefined control sequence.
<argument> ...tockwidth \paperheight \stockheight
\fi \ifdim \paperwidth >\z...
l.5 \begin{document}
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.
! Missing number, treated as zero.

l.5 \begin{document}
A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)

如能得到任何解释/解决方法，我将非常感激。
