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

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。它位于文件夹中C:texlive
我以前已经安装了MikTex，并一直试图解决这个问题，现在几个小时，请帮助我!
除了一个(工作的)LaTeX安装，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或更高版本)。这三个组件的所有的二进制文件需要位于PATH变量中。既然您指出可以从提示符调用latex，那么这个似乎已经在您的PATH中了。
我建议您检查您的系统上是否有(1)正确的dvipng和Ghostscript二进制文件，(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，你可以找到两个部分("可能的挂起"one_answers"故障排除")，这可能会帮助你进一步。
