我使用CX_Freeze冻结了我的python程序之一。构建系统在Windows中可以正常工作。我可以创建一个具有可执行文件和必要依赖项的目录,该目录将在任何Windows系统中运行。
当我在Linux中尝试相同的操作时,构建部分
python setup.py
工作良好。但是,当我尝试运行生成的可执行文件时,出现以下错误。
File "/usr/local/lib/python2.7/dist-packages/cx_Freeze/initscripts/Console.py", line 27, in <module>
exec code in m.__dict__
File "test.py", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/guidata/__init__.py", line 540, in <module>
import guidata.config
File "/usr/local/lib/python2.7/dist-packages/guidata/config.py", line 19, in <module>
add_image_module_path("guidata", "images")
File "/usr/local/lib/python2.7/dist-packages/guidata/configtools.py", line 100, in add_image_module_path
add_image_path(get_module_data_path(modname, relpath=relpath), subfolders)
File "/usr/local/lib/python2.7/dist-packages/guidata/configtools.py", line 86, in add_image_path
for fileobj in os.listdir(path):
OSError: [Errno 20] Not a directory: '/home/user/tmp/dist/library.zip/guidata/images'
看来guidata试图在不存在的library.zip/guidata/images目录下查找图像。我确保在Windows和Linux上运行相同版本的guidata,cx_Freeze。感谢您为解决该问题提供的任何帮助。
最小的例子
import guidata
_app = guidata.qapplication() # not required if a QApplication has already been created
import guidata.dataset.datatypes as dt
import guidata.dataset.dataitems as di
class Processing(dt.DataSet):
"""Example"""
a = di.FloatItem("Parameter #1", default=2.3)
b = di.IntItem("Parameter #2", min=0, max=10, default=5)
type = di.ChoiceItem("Processing algorithm",
("type 1", "type 2", "type 3"))
param = Processing()
param.edit()
设定档
import sys
import os
"""Create a stand-alone executable"""
try:
import guidata
from guidata.disthelpers import Distribution
except ImportError:
raise ImportError, "This script requires guidata 1.4+"
def create_executable():
"""Build executable using ``guidata.disthelpers``"""
dist = Distribution()
dist.setup(name='Foo', version='0.1',
description='bar',
script="test.py", target_name='test.exe')
dist.add_modules('guidata', 'guiqwt')
# Building executable
dist.build('cx_Freeze')
if __name__ == '__main__':
create_executable()
最佳答案
好。这是我自己的问题的答案。经过大量挖掘之后,我意识到这是guidata和/或python的os.path模块中的错误。这是怎么回事。在guidata模块上的configtools.py文件中,有一个函数get_module_data_path,该函数检查/foo/bar/library.zip/yap之类的路径的父“目录”是否为文件。
import os.path as osp
...
...
datapath = get_module_path(modname)
parentdir = osp.join(datapath, osp.pardir)
if osp.isfile(parentdir):
# Parent directory is not a directory but the 'library.zip' file:
# this is either a py2exe or a cx_Freeze distribution
datapath = ...
现在测试
osp.isfile("/foo/bar/library.zip/yap/..")
在Windows中返回True,在Linux中返回False。这会破坏代码。尚不清楚Python文档是否说明这是错误还是预期的行为。
目前,我没有解决方案,但有破解方法。我将上面的代码更改为:
import os.path as osp
...
...
datapath = get_module_path(modname)
parentdir = osp.join(datapath, osp.pardir)
parentdir2 = osp.split(datapath.rstrip(os.path.sep))[0]
if osp.isfile(parentdir) or osp.isfile(parentdir2):
# Parent directory is not a directory but the 'library.zip' file:
# this is either a py2exe or a cx_Freeze distribution
datapath = ...
一切都很好。
