python scrapy conversion to exe file using pyinstaller

Question

I am trying to convert a scrapy script to a exe file. The main.py file looks like this:

from scrapy.crawler import CrawlerProcess
from amazon.spiders.amazon_scr         


        

Answer 1

I had the same situation.
Instead of trying to make pyinstaller count this file (I failed all my attempts to do it) I decided to check and change some part of scrapy code in order to avoid this error.

I noticed that there is only one place where \scrapy\VERSION file used-- \scrapy\__init__.py
I decided to hardcode that value from scrapy\version by changing scrapy__init__.py :

#import pkgutil
__version__ = "1.5.0" #pkgutil.get_data(__package__, 'VERSION').decode('ascii').strip()
version_info = tuple(int(v) if v.isdigit() else v
                     for v in __version__.split('.'))
#del pkgutil

After this change there is no need to store version in external file. As there is no reference to \scrapy\version file - that error will not occure.

After that I had the same FileNotFoundError: [Errno 2] with \scrapy\mime.types file.
There is the same situation with \scrapy\mime.types - it used only in \scrapy\responsetypes.py

...
#from pkgutil import get_data
...
    def __init__(self):
        self.classes = {}
        self.mimetypes = MimeTypes()
        #mimedata = get_data('scrapy', 'mime.types').decode('utf8')
        mimedata = """
        Copypaste all 750 lines of \scrapy\mime.types here
"""
        self.mimetypes.readfp(StringIO(mimedata))
        for mimetype, cls in six.iteritems(self.CLASSES):
            self.classes[mimetype] = load_object(cls)

This change resolved FileNotFoundError: [Errno 2] with \scrapy\mime.types file. I agree that hardcode 750 lines of text into python code is not the best decision.

After that I started to recieve ModuleNotFoundError: No module named scrapy.spiderloader . I added "scrapy.spiderloader" into hidden imports parameter of pyinstaller.
Next Issue ModuleNotFoundError: No module named scrapy.statscollectors.
Final version of pyinstaller command for my scrapy script consist of 46 hidden imports - after that I received working .exe file.
