Pyinstaller scrapy error:
You need to create a scrapy folder under the same directory as runspider.exe (the exe file generated by pyinstaller).
Then copy the "VERSION" and "mime.types" files(default path: %USERPROFILE%\AppData\Local\Programs\Python\Python37\Lib\site-packages\scrapy) to the scrapy you just created in the scrappy folder you create . (If you only copy "VERSION", you will be prompted to find the "mime.types" file)
After installing all dependencies for scrapy on windows 32bit. I've tried to build an executable from my scrapy spider. Spider script "runspider.py" works ok when running as "python runspider.py"

I'm extremely helpful for any kind of help. I need to know how to build standalone exe from scrapy spider for windows. 
Thank you very much for any help.
