如果无法访问所需的软件包，如何获取PHP来编译LaTeX文档(www-data)? [英] How can I get PHP to compile a LaTeX document if it (www-data) can't get access to the required packages?

问题描述

我有一个PHP脚本，可使用以下命令来编译LaTeX文档:

I have a PHP script that compiles LaTeX documents with the use of:

exec('cd /path/to/doc && /usr/bin/latexmk -pdf filename.tex');

这适用于我的某些LaTeX文档，但我的最新文档无法编译，并且查看日志显示:

This is working for some of my LaTeX documents but my latest document doesn't compile and a look at the log reveals:

!pdfTeX error: pdflatex (file ecrm1000): Font ecrm1000 at 600 not found
==> Fatal error occurred, no output PDF file produced!

我发现这是LaTeX无法看到所需字体包的结果.当我在用户名下运行相同的compile命令时，文档将按应有的方式进行编译.所以我的问题是，如何获得PHP(作为www-data执行)以访问必要的LaTeX软件包?

Which I have found is the result of LaTeX not being able to see the required font packages. When I run the same compile command under my username the document compiles as it should. So my question is, how can I get PHP (executing as www-data) to get access to the necessary LaTeX packages?

我尝试使用以下方式在www-data帐户下安装所需的软件包:

I have tried installing the required package under the www-data account using:

sudo -u www-data sudo apt-get install texlive-fonts-recommended

但是它要求输入www-data的密码，我不相信这是我设置的，也不是我扔给它的任何东西.

but it askes for www-data's password, which I don't believe was set by me and isn't anything I've thrown at it.

如果有任何帮助，我正在运行Ubuntu 12.04.

I'm running Ubuntu 12.04 if it's any help.

推荐答案

sudo mktexpk --destdir /usr/share/texmf-texlive/fonts/pk/ljfour/jknappen/ec/ --mfmode / --bdpi 600 --mag 1+0/600 --dpi 600 ecrm1000

...使字体对所有用户可用(与missingfont.log中的字体相同，但带有--destdir参数).

... makes the font available for all users (same as in missingfont.log but with --destdir argument).
