问题
I have created a scrapy spider and successfully converted to windows executable using pyinstaller with disc folder.
In order to do that, I have to make some slight changes in the scrapy site-packages and add those packages in the windows disc folder, it works perfectly,
How can I make this into a single exe with the commented scrapy packages from the disc folder?
I have already tried with --OneFile command in pyinstaller, but it shows the scrapy error?

Very similar issue discussed here: python scrapy conversion to exe file using pyinstaller
Initially I used auto-py-to-exe package (which is actually GUI for pyinstaller)
I added following line to auto-py-to-exe -> advanced settings -> hidden import:
scrapy.spiderloader,scrapy.statscollectors,scrapy.logformatter,scrapy.extensions,scrapy.extensions.corestats,scrapy.extensions.corestats,scrapy.extensions.telnet,scrapy.extensions.memusage,scrapy.extensions.memdebug,scrapy.extensions.closespider,scrapy.extensions.feedexport,scrapy.extensions.logstats,scrapy.extensions.spiderstate,scrapy.extensions.throttle,scrapy.core.scheduler,scrapy.squeues,queuelib,scrapy.core.downloader,scrapy.downloadermiddlewares,scrapy.downloadermiddlewares.robotstxt,scrapy.downloadermiddlewares.httpauth,scrapy.downloadermiddlewares.downloadtimeout,scrapy.downloadermiddlewares.defaultheaders,scrapy.downloadermiddlewares.useragent,scrapy.downloadermiddlewares.retry,scrapy.downloadermiddlewares.ajaxcrawl,scrapy.downloadermiddlewares.redirect,scrapy.downloadermiddlewares.httpcompression,scrapy.downloadermiddlewares.redirect,scrapy.downloadermiddlewares.cookies,scrapy.downloadermiddlewares.httpproxy,scrapy.downloadermiddlewares.stats,scrapy.downloadermiddlewares.httpcache,scrapy.spidermiddlewares,scrapy.spidermiddlewares.httperror,scrapy.spidermiddlewares.offsite,scrapy.spidermiddlewares.referer,scrapy.spidermiddlewares.urllength,scrapy.spidermiddlewares.depth,scrapy.pipelines,scrapy.dupefilters,scrapy.core.downloader.handlers.datauri,scrapy.core.downloader.handlers.file,scrapy.core.downloader.handlers.http,scrapy.core.downloader.handlers.s3,scrapy.core.downloader.handlers.ftp,scrapy.core.downloader.webclient,scrapy.core.downloader.contextfactory
After that following command appeared in last text box (don't forget to change path to your script) :
pyinstaller -y -F --hidden-import scrapy.spiderloader --hidden-import scrapy.statscollectors --hidden-import scrapy.logformatter --hidden-import scrapy.extensions --hidden-import scrapy.extensions.corestats --hidden-import scrapy.extensions.corestats --hidden-import scrapy.extensions.telnet --hidden-import scrapy.extensions.memusage --hidden-import scrapy.extensions.memdebug --hidden-import scrapy.extensions.closespider --hidden-import scrapy.extensions.feedexport --hidden-import scrapy.extensions.logstats --hidden-import scrapy.extensions.spiderstate --hidden-import scrapy.extensions.throttle --hidden-import scrapy.core.scheduler --hidden-import scrapy.squeues --hidden-import queuelib --hidden-import scrapy.core.downloader --hidden-import scrapy.downloadermiddlewares --hidden-import scrapy.downloadermiddlewares.robotstxt --hidden-import scrapy.downloadermiddlewares.httpauth --hidden-import scrapy.downloadermiddlewares.downloadtimeout --hidden-import scrapy.downloadermiddlewares.defaultheaders --hidden-import scrapy.downloadermiddlewares.useragent --hidden-import scrapy.downloadermiddlewares.retry --hidden-import scrapy.downloadermiddlewares.ajaxcrawl --hidden-import scrapy.downloadermiddlewares.redirect --hidden-import scrapy.downloadermiddlewares.httpcompression --hidden-import scrapy.downloadermiddlewares.redirect --hidden-import scrapy.downloadermiddlewares.cookies --hidden-import scrapy.downloadermiddlewares.httpproxy --hidden-import scrapy.downloadermiddlewares.stats --hidden-import scrapy.downloadermiddlewares.httpcache --hidden-import scrapy.spidermiddlewares --hidden-import scrapy.spidermiddlewares.httperror --hidden-import scrapy.spidermiddlewares.offsite --hidden-import scrapy.spidermiddlewares.referer --hidden-import scrapy.spidermiddlewares.urllength --hidden-import scrapy.spidermiddlewares.depth --hidden-import scrapy.pipelines --hidden-import scrapy.dupefilters --hidden-import scrapy.core.downloader.handlers.datauri --hidden-import scrapy.core.downloader.handlers.file --hidden-import scrapy.core.downloader.handlers.http --hidden-import scrapy.core.downloader.handlers.s3 --hidden-import scrapy.core.downloader.handlers.ftp --hidden-import scrapy.core.downloader.webclient --hidden-import scrapy.core.downloader.contextfactory "C:/path/script.py"
If after this your command return: ImportError: No module named 'modulename' - add missing module to hidden imports and repeat this process with new extended hidden imports.
(I repeated this procedure 48 times in order to receive working exe file (and receive list of sumbodules)!!)
回答2:
Fixed it by using --hidden imports in the spec file. Pyinstaller doesn't support all second level module imports in scrapy.
Run the pyinstaller command, Just update the spec file with below hidden import changes,
hiddenimports=['scrapy.spiderloader','scrapy.statscollectors','scrapy.logformatter','scrapy.extensions','scrapy.extensions.logstats', 'scrapy.extensions.corestats','scrapy.extensions.memusage','scrapy.extensions.feedexport','scrapy.extensions.memdebug', 'scrapy.extensions.closespider','scrapy.extensions.throttle','scrapy.extensions.telnet','scrapy.extensions.spiderstate', 'scrapy.core.scheduler','scrapy.core.downloader','scrapy.downloadermiddlewares','scrapy.downloadermiddlewares.robotstxt', 'scrapy.downloadermiddlewares.httpauth','scrapy.downloadermiddlewares.downloadtimeout','scrapy.downloadermiddlewares.defaultheaders', 'scrapy.downloadermiddlewares.useragent','scrapy.downloadermiddlewares.retry','scrapy.core.downloader.handlers.http', 'scrapy.core.downloader.handlers.s3','scrapy.core.downloader.handlers.ftp','scrapy.core.downloader.handlers.datauri', 'scrapy.core.downloader.handlers.file','scrapy.downloadermiddlewares.ajaxcrawl','scrapy.core.downloader.contextfactory', 'scrapy.downloadermiddlewares.redirect','scrapy.downloadermiddlewares.httpcompression','scrapy.downloadermiddlewares.cookies', 'scrapy.downloadermiddlewares.httpproxy','scrapy.downloadermiddlewares.stats','scrapy.downloadermiddlewares.httpcache', 'scrapy.spidermiddlewares','scrapy.spidermiddlewares.httperror','scrapy.spidermiddlewares.offsite','scrapy.spidermiddlewares.referer', 'scrapy.spidermiddlewares.urllength','scrapy.spidermiddlewares.depth','scrapy.pipelines','scrapy.dupefilters','queuelib', 'scrapy.squeues',]
Fixed with 45 module import issues. Using --onefile helps to run the scrapy project in a single executable. Hope anyone finds it useful.
