Matplotlib：TexLive 安装不起作用

Question

我正在尝试在我的情节中使用 Latex。 但是，如果我使用plt.rc('text', usetex=True) ，我会收到以下错误。

回溯（最近一次通话最后）：

The above exception was the direct cause of the following exception:

我已经安装了 TexLive，并且可以通过键入 latex 从命令提示符调用它。 它位于文件夹C:\texlive

我以前安装了 MikTex 并试图解决这个问题已经好几个小时了，请帮助我！

Answer 1

除了（工作） LaTeX安装之外，您还需要dvipng （您可以检查它是否包含在您的 TexLive 发行版中，否则下载它）和Ghostscript （9.0 版或更高版本）。 所有这三个组件的二进制文件都需要位于您的PATH变量中。 由于您表明您可以从提示符中调用latex ，因此这个似乎已经在您的PATH中。

我建议您检查（1）您的系统上是否有正确的dvipng和Ghostscript二进制文件，以及（2）它们是否位于您的PATH上。

如果这些都没有帮助，您可以查看matplotlib usetex 文档页面。 在页面底部附近，您可以找到两个部分（“可能挂断”和“疑难解答”），它们可能会进一步帮助您。
