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

问题描述

我最近将我的笔记本电脑升级到了 Snow Leopard，将 TeX 更新到了 3.1415926 版(TeX Live 2011/MacPorts 2011_5)，并安装了 Python 2.7.3.在所有这些安装之后，我运行了 macport selfupdate 和 macport upgrade 过时.但是，现在当我尝试在 matplotlib 中使用 TeX 时，我收到以下信息:

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 After all these installs, I ran macport selfupdate and macport upgrade outdated.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:

类似于上一个问题，我尝试通过以下方式在我的 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，这不起作用，并显示相同的错误消息.我还尝试了 tex 的路径，以及上一个问题中的示例.没有变化.

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.

然后我试图通过以下方式强制可能丢失的包:

I then tried to force possibly missing packages via:

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

然而，这也不起作用.

让我的绘图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

错误消息说您缺少 type1cm 包.MacPorts 似乎将它作为 texlive-latex-extra 的一部分包含在内.

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