python - 在 Mac 上使用 Tkinter 的 NSException

Question

我使用 Tkinter 创建一个 GUI 窗口并选择一个文件。我使用的代码如下:

Tk().withdraw()
file = askopenfilenames(title='Chose transition file')

当我在 Windows 和 OSX 中单独运行它时，它运行。但是，我需要它成为更大脚本的一部分，该脚本可以在 this link 中找到。 (第 88-89 行)。这个较大的脚本在 Windows 操作系统中可以正常运行，但是当我在 OSX 中运行它时，出现以下错误:

如果我注释掉 Tkinter 代码行，代码在 OSX 中运行良好。

你能告诉我我应该怎么做才能克服这个问题吗？

Answer 1

按照 this question 中的答案进行操作

OSX 上的 TK 和 IDLE 存在一个已知问题，因为:

Python's integrated development environment, IDLE, and the tkinter GUI toolkit it uses, depend on the Tk GUI toolkit which is not part of Python itself. For best results, it is important that the proper release of Tcl/Tk is installed on your machine.

详情:

If you are using Python from a python.org 64-bit/32-bit Python installer for Mac OS X 10.6 and later, you should only use IDLE or tkinter with an updated third-party Tcl/Tk 8.5 (not 8.6), like ActiveTcl 8.5 installed.

If you are using Mac OS X 10.6, do not use IDLE or Tkinter from the Apple-supplied Python 2.6.1 in Mac OS X 10.6. If possible, install and use a newer version of Python and of Tcl/Tk.

If you are using Mac OS X 10.7 or later, the Apple-supplied Tcl/Tk 8.5 still has serious bugs that can cause application crashes. If you wish to use IDLE or Tkinter, install and use a newer version of Python and of Tcl/Tk.
