Matplotlib，py2exe中的mathtext findfont問題應用程序

我創建了一個使用Matplotlib/mathtext字體的wxapp，並將它轉換爲一個帶有py2exe的exe文件。結果EXE運行罰款在我的電腦上。Matplotlib，py2exe中的mathtext findfont問題應用程序

而且我也看到了這結尾的回溯：

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

無法找到的字體，但是我把它在其他地方，當它與app.exe.log以下崩潰都由matplotlib/mathtext使用。

我發現setup.py中的兩個方法，我嘗試獲取data_files（使用glob和matplotlib.get_py2exe_datafiles）沒有工作，沒有什麼複製到我的mpl-data/fonts目錄。源目錄：C：\ Python27 \ Lib \ site-packages \ matplotlib \ mpl-data \ fonts包含3個文件夾：afm，pdfcorefonts & ttf。 ttf文件夾是上面提到的mathtext字體所在的位置。

我試着手動將整個mpl-data文件夾複製到dist文件夾中，然後在setup.py上運行py2exe並修改glob以獲得3字體目錄，但仍然得到相同的錯誤。

看來，matplotlib的font_manager中的findfont方法在通過py2exe運行後無法工作，我猜測mathtext.pyo中的_get_glyph嘗試使用Bitstream Vera Sans字體時會崩潰。

您可能會給'pyinstaller'試試吧。我發現默認情況下它比mat2更友好，而不是'py2exe'。 http://www.pyinstaller.org/ –

我已經嘗試pyinstaller快速使用默認值，它也崩潰在新的機器上，但沒有日誌。你知道如何讓exe生成一個日誌或使窗口打開pyinstaller？ – Jonno

沒關係，我正在變厚。從cmd行運行我得到與pyinstaller相同的錯誤： – Jonno

使用matplotlib.get_py2exe_datafiles()對我來說工作正常。只要確保你使用的是最新版本的matplotlib的和setup.py使用它像這樣：

datafiles = matplotlib.get_py2exe_datafiles() 

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