Python:无法在Matplotlib中渲染Tex [英] Python: Unable to Render Tex in Matplotlib

问题描述

我最近将笔记本电脑升级到Snow Leopard，将TeX升级到了版本3.1415926(TeX Live 2011/MacPorts 2011_5)，并安装了Python 2.7.3.完成所有这些安装后，我运行了macport selfupdate和macport升级已过时的情况.但是，现在，当我尝试在matplotlib中使用TeX时，会收到以下消息:

I recently upgraded my laptop to Snow Leopard, updated TeX to Version 3.1415926 (TeX Live 2011/MacPorts 2011_5), and installed Python 2.7.3. After all these installs, I ran macport selfupdate and macport upgrade outdated. However, now when I try to use TeX in matplotlib, I receive the following:

LaTeX was not able to process the following string:'lp'

类似于上一个问题 ，我尝试通过以下方式在python代码中设置路径:

Similar to this previous question, I tried setting the path in my python code via:

os.environ['PATH'] = os.environ['PATH'] + ':/opt/local/bin/latex'

，因为which latex产生了/opt/local/bin/latex.但是，该操作不起作用，并带有相同的错误消息.我还尝试了tex的路径，以及上一个问题中的示例.没变化.

since which latex yielded /opt/local/bin/latex. However, that didn't work, with the same error message. I also tried the path to tex, as well as the example from the previous question. No change.

然后我尝试通过以下方式强制可能丢失的包裹:

I then tried to force possibly missing packages via:

matplotlib.rcParams['text.latex.preamble']=[r"\usepackage{amsmath}"]

但是，那也不起作用.

however, that also did not work.

我想让我的地块工作的唯一方法是说rc('text', usetex=False)，这并不理想.任何帮助将不胜感激.

The only way I can get my plots to work is to say rc('text', usetex=False), which is not ideal. Any help would be much appreciated.

推荐答案

错误消息表明您缺少type1cm软件包.似乎 MacPorts将其包含为texlive-latex-extra 的一部分.

The error message says you're missing the type1cm package. It seems that MacPorts includes it as part of texlive-latex-extra.
