在具有导入程序的py文件中执行py2exe时,会导致错误。
如何避免此错误?
我准备了test.py和test_setup.py(用于py2exe),如下所示。
test.py是一个简单的程序,用于显示参数指定的data文件的数据。
on cmd.exe:
\python test_setup.py py2exe=>成功
\python test.py test.fits
[[[574 574 579 ..., 579 585 581]
[574 582 583 ..., 582 579 577]
[581 583 578 ..., 572 580 580]
...,
[584 585 580 ..., 584 582 579]
[585 583 582 ..., 586 575 578]
[584 580 583 ..., 585 585 589]]]=>成功
\dist\test.exe test.fits

看着这条线撞上了
dump.__doc__ += _tdump_file_format.replace('\n', '\n ')看起来pyfits正在做一些类级的docstring操作。这可以合理地被认为是一个bug,因为不能总是假定一个方法的__doc__将是一个字符串,就像使用优化编译(就像您一样)的情况一样,它除其他外,删除了所有的docstring。
我认为最简单的解决办法要么是禁用优化(至少目前是这样),要么是修补程序来删除这一行并与之类似。
