使用cx_Freeze或py2exe发行打包scrapy spider [英] Issue packaging scrapy spider with cx_Freeze or py2exe

问题描述

我已经使用Scrapy和wxPython创建了一个抓取工具，该抓取工具可以按预期工作，并以CSV格式将包含结果的文件导出到桌面。我正在尝试使用以下命令行将其打包为带有cx_Freeze的可执行文件：

I've created a scraper with Scrapy and wxPython which works as expected, exporting a file with results to the desktop in CSV format. I'm attempting to package this into an executable with cx_Freeze using the below command prompt line:

cxfreeze ItemStatusChecker.py --target-dir dist

这似乎很好用，使用ItemStatusChecker.exe构建dist目录

This seems to work fine, building the dist directory with ItemStatusChecker.exe

但是，当我打开ItemStatusChecker.exe时，在命令提示符下出现以下错误，并且我的GUI无法启动：

However, when I open ItemStatusChecker.exe, I get the below error in the command prompt and my GUI does not launch:

Traceback (most recent call last):
    File "C:\Python27\lib\site-packages\cx_Freeze\initscripts\Console.py", line 27, in <module>
      exec code in m.__dict__
    File "ItemStatusChecker.py", line 6, in <module>
    File "C:\Python27\lib\site-packages\scrapy\__init__.py", line 6, in <module>
      __version__ = pkgutil.get_data(__package__, 'VERSION').strip()
    File "C:\Python27\lib\pkgutil.py", line 591, in get_data
      return loader.get_data(resource_name_)
IOError: [Errno 2] No such file or directory: 'scrapy\\VERSION'

我也尝试通过py2exe运行它。创建dist目录似乎也可以正常工作，但是尝试启动exe时出现类似错误：

I've tried running it through py2exe as well. This also seems to work fine, creating the dist directory, but I get a very similar error when trying to launch the exe:

Traceback (most recent call last):
  File "ItemStatusChecker.py", line 6, in <module>
  File "scrapy\__init__.pyc", line 6, in <module>
  File "pkgutil.pyc", line 591, in get_data
IOError: [Errno 2] No such file or directory: 'scrapy\\VERSION'

我是python新手，所以让我知道是否遗漏了任何必要的细节。预先感谢您提供任何建议！

I'm a python newbie, so let me know if I left out any necessary details. Thank you in advance for any advice you can offer!

推荐答案

请看一下（ http://cx-freeze.readthedocs.org/en/latest/faq.html#using-数据文件）

我使用cx-freeze的解决方案：

My solution using cx-freeze:

修改文件 C：\Python2.7\Lib\站点软件包\scrapy__init __。py

import sys
# Scrapy version
import pkgutil
if getattr(sys, 'frozen', False):
    __version__ = 'VERSION'.decode('ascii').strip()
else:
    __version__ = pkgutil.get_data(__package__, 'VERSION').decode('ascii').strip()

和文件 C：\Python2.7\Lib\site-packages\scrapy\responsetypes.py

import sys
from mimetypes import MimeTypes
from pkgutil import get_data
...
   def __init__(self):
        self.classes = {}
        self.mimetypes = MimeTypes()
        if getattr(sys, 'frozen', False):
            mimedata = 'mime.types'
        else:
            mimedata = get_data('scrapy', 'mime.types')
        self.mimetypes.readfp(StringIO(mimedata))

并在setup.py中包含此生成exe选项

And in setup.py include this build exe option

"include_files": [("C:\\Python27\\Lib\\site-packages\\scrapy\\VERSION","VERSION"),
    ("C:\\Python27\\Lib\\site-packages\\scrapy\\mime.types","mime.types")]}
