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

在安装scrapy时遇到问题

环境:win10(64位), Python3.6(64位)

安装scrapy:

1、安装wheel(安装后,便支持通过wheel文件安装软件)

pip3 install wheel

2、安装lxml、pyopenssl

lxml:解析XML的库,很强大,做爬虫BS4,selenium,XPATH都会用到

pip3 install lxml
pip3 install pyopenssl

3、安装pywin32

下载网址: https://sourceforge.net/projects/pywin32/files/pywin32/

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

根据自己python版本下载64位或32位((注意:pywin32版本跟随Python版本,即如果win是64位,但python是32位,pywin32要装32位的,与win无关))

双击安装(可能会遇到下列错误是注册表问题)

安装第三方库出现Python version 3.6 required, which was not found in the registry错误解决

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

建立一个文件 register.py 内容如下. 然后执行该脚本.

import sys

from winreg import *

# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix regpath = "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、下载twisted

下载twisted的wheel文件:http://www.lfd.uci.edu/~gohlke/pythonlibs/

pip3 install 下载目录\Twisted-17.9.0-cp36-cp36m-win_amd64.whl

安装可能会报错

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

说明电脑需要安装visual C++ Build Tools 2015

5、安装scrapy

pip3 install scrapy

6、大功告成

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