Question

我创建了一个wxapp，它使用Matplotlib / mathtext字体并将其转换为带有py2exe的exe。结果exe在我的电脑上运行正常。但是，当我把它带到其他地方时，它会在app.exe.log中崩溃：

我还看到一个追溯结尾：

...
File "matplotlib\mathtext.pyo", line 720, in _get_glyph
KeyError: 98

无法找到的字体全部由matplotlib / mathtext使用。

我发现setup.py中我尝试获取data_files的两个方法（使用glob和matplotlib.get_py2exe_datafiles）都没有工作，没有任何东西被复制到我的mpl-data / fonts目录。源目录：C：\ Python27 \ Lib \ site-packages \ matplotlib \ mpl-data \ fonts包含3个文件夹：afm，pdfcorefonts＆amp; TTF。 ttf文件夹是上面提到的mathtext字体所在的位置。

我尝试在setup.py上运行py2exe后手动将整个mpl-data文件夹复制到dist文件夹中，并修改glob以获取3个字体目录，但我仍然得到相同的错误。

似乎matplotlib的font_manager中的findfont方法在运行py2exe后无效，我想当mathtext.pyo中的_get_glyph尝试使用Bitstream Vera Sans字体时会崩溃。

使用matplotlib.get_py2exe_datafiles()对我来说很好。请确保您使用的是最新版本的matplotlib并在setup.py中使用它：

datafiles = matplotlib.get_py2exe_datafiles()

setup(...
      ...
      data_files = datafiles,
      ...
     )

Matplotlib，在py2exe应用程序中的mathtext findfont问题
