使用text.usetex时无法将matplotlib图形保存到Windows中.eps：真

Question

当我运行以下代码时：http://dpaste.com/0210P09在我的Linux发行版上一切都很好。

但是，在Windows7（64位）中，我无法成功地将其保存在eps或svg中。

这是我得到的错误：

如果我使用text.usetex : False，我一点问题都没有。

我已经安装了livetex full和Ghostscript。

有什么建议可以尝试解决吗？

Answer 1

这里有两个问题。第一个也是次要的一个是

C： \Users\12151056\AppData\Local\Continum\Anaconda3\lib\site package\matplotlib\backends\backend_ps.py"，第1556行

你应该更改

fh.read()

至

fh.read().decode()

这是一个Python 2/3错误，发生在处理Ghostscript出错的事实时。

主要问题是matplotlib找不到Ghostscript，因为它不在路径环境变量中。可以通过打开命令提示符并尝试命令gswin32c或gs来进行检查。如果找不到这些命令，则必须将这些Ghostscript可执行文件的路径添加到路径环境变量中。在我的情况下是：

C： \Program Files（x86）\gs\gs8.54\bin

但这取决于您的安装路径。
