96. python version 3.6 required, which was not fount in the registry (install scrapy in python3.6), fountscrapy

Problems encountered during scrapy Installation

Environment: win10 (64-bit), Python3.6 (64-bit)

Install scrapy:

1. Install wheel (after installation, the software can be installed through the wheel file)

pip3 install wheel

2. Install lxml and pyopenssl

Lxml: the Library for parsing XML, which is very powerful. It is used for crawling BS4, selenium, and XPATH.

pip3 install lxmlpip3 install pyopenssl

3. Install pywin32

Download URL: https://sourceforge.net/projects/pywin32/files/pywin32/

Download 64-bit or 32-bit python based on your own version (Note: The pywin32 version follows the Python version, that is, if the win is 64-bit, but the python version is 32-bit, the pywin32 version must be 32-bit, (not related to win ))

Double-click installation (the following error may be caused by registry issues)

After installing a third-party library, the following error occurs: Python version 3.6 required, which was not found in the registry.

Create a file register. py with the following content. then execute the script.

import sysfrom winreg import *# tweak as necessaryversion = sys.version[:3]installpath = sys.prefixregpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)installkey = "InstallPath"pythonkey = "PythonPath"pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (    installpath, installpath, installpath)def RegisterPy():    try:        reg = OpenKey(HKEY_CURRENT_USER, regpath)    except EnvironmentError as e:        try:            reg = CreateKey(HKEY_CURRENT_USER, regpath)            SetValue(reg, installkey, REG_SZ, installpath)            SetValue(reg, pythonkey, REG_SZ, pythonpath)            CloseKey(reg)        except:            print("*** Unable to register!")            return        print("--- Python", version, "is now registered!")        return    if (QueryValue(reg, installkey) == installpath and                QueryValue(reg, pythonkey) == pythonpath):        CloseKey(reg)        print("=== Python", version, "is already registered!")        return    CloseKey(reg)    print("*** Unable to register!")    print("*** You probably have another Python installation!")if __name__ == "__main__":    RegisterPy()

4. Download twisted

Download the twisted wheel file: http://www.lfd.uci.edu /~ Gohlke/pythonlibs/
