我最近安装了 Ubuntu 18.04（不升级，全新安装）。在 Ubuntu 18.04 中，Inkscape 中的渲染 LaTeX 功能不起作用。以下是错误输出：

*** WARNING - the DELAYBIND command has been deprecated, and will be

           removed in the next version. For now you can restore

           the behaviour by using -dREALLYDEALYBIND but if you

           require continued use of this command you should contact

           the Ghostscript developers. Commercial customers of

           Artifex should email their support contact, free users

           are encouraged to talk to us on the #ghostscript IRC

           channel on irc.freenode.net.



Unrecoverable error: undefined in DELAYBIND

PostScript/PDF Interpreter finished. Return status 65280 executed command : /usr/bin/gs -q -dDELAYBIND -dWRITESYSTEMDICT -dNODISPLAY -dNOEPS "/tmp/psin5eNNQ0"

The interpreter seems to have failed, cannot proceed !

从谷歌搜索，我发现问题是由于ghostscript而出现的。Render>LaTeX扩展实际上调用pstoeditwhich in terns 调用ghostscript使用flag从DELAYBIND转换LaTeX为SVG. 但在较新版本中ghostscript该标志DELAYBIND已被弃用。解决方案是降级ghostscript到或低于 9.20 版本。以下是我尝试降级ghostscript但没有成功的方法。

从 apt 或 apttitute 降级 ghostscript

我尝试ghostrict使用以下命令降级。

sudo aptitude install ghostscript=9.18~dfsg~0-0ubuntu2

或者通过使用

sudo apt install ghostscript=9.18~dfsg~0-0ubuntu2

我得到以下输出

Unable to find a version "9.18~dfsg~0-0ubuntu2" for the package "ghostscript"

或者

E: Version '9.18~dfsg~0-0ubuntu2' for 'ghostscript' was not found

我尝试了其他版本，例如 9.20 的 ghost 脚本。没有任何效果。

从 ghostscript 网站安装：

我已经ghostscript从下载ghostscript website，并使用以下命令安装

sudo ./configure
sudo make
sudo make install

似乎安装完成了，但是如果我正在运行命令

ghostscript  --version

它显示版本为 9.22。

我能找到的所有在线解决方案都指向降级ghostscript. 但我不知道如何在 Ubuntu 18.04 中做到这一点。

有什么解决办法吗？
