在Python 3.4中創建跨平臺GUI

Question

我正在構建一個GUI，它可以將.txt或.xlsx文件作爲輸入，對它們執行一些操作並將結果作爲圖返回。我爲GUI使用Python 3.4和Tkinter 8.5。

它有一個用於選擇文件類型的下拉列表和一個用於打開對話框以選擇文件的按鈕。然後它將該文件的內容保存到同一目錄中的不同文件中。它還有一個退出程序的按鈕，一個文本框和一個標籤，我只是在玩，並沒有達到任何目的。

當我運行datagui.py文件時，GUI工作。不過，我也想製作一個跨平臺的文件，不需要Python來運行它。我使用cx_freeze爲此目的作出了一個exe和寫了下面的setup.py文件來構建它（cx_Freeze網站上提供過）：

import sys 
from cx_Freeze import setup, Executable 

base = None 
if sys.platform == "win32": 
    base = "Win32GUI" 

setup( name = "datagui", 
     version = "0.1", 
     description = "My first GUI application", 
     executables = [Executable("datagui.py", base=base)]) 

當我嘗試運行datagui.exe文件地處...\build\exe.win-amd64-3.4目錄中，我收到以下錯誤：

我在做什麼錯在這裏？

您可能想要查看您的matplotlib配置。

See this previous answer on matplotlib import

您需要指明要matplotlib實現後端的類型。

import matplotlib 
matplotlib.use("Agg")
