python - How to create a single executable file in windows 10 with scrapy and pyinstaller?

Question

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)!!)
