在OSX中使用usetex的问题10.8

Question

我最近升级到OSX 10.8（Mountain Lion），如果我尝试在我的剧情标签中使用乳胶标记，我的python安装现在行为异常。

下面的代码完美运行：

plt.figure() 
plt.plot(rand(51), rand(51)) 
plt.show() 

然而，这并不：

plt.rc('text', usetex=True) 
plt.figure() 
plt.plot(rand(51), rand(51)) 
plt.show() 

的错误，我回来是：

有其他人遇到这个问题？我该如何解决？

也许TeX和实用程序不在您的$PATH上？你应该设置一些东西，这样如果你在命令行输入“tex”或“kpsewhich”，你就可以调用这些程序（即得到一些输出，而不是找到“command not found”）。如果您以前安装过TeX Live，请确保/usr/texbin位于搜索路径中。
