環境:win10(64位), Python3.6(64位)python
一、安裝pyhthonwindows
這個就很少說了,對應版本就下載對應的依賴包ide
二、安裝pywin32ui
在windows下,必須安裝pywin32,安裝地址:http://sourceforge.net/projects/pywin32/spa
下載對應版本的pywin32,直接雙擊安裝便可,安裝完畢以後驗證:.net
(注意:pywin32版本跟隨Python版本,即若是win是64位,但python是32位,pywin32要裝32位的)命令行
安裝pywin32須要把Python的路徑寫入註冊表中,運行下面腳本:code
# -*- coding: utf-8 -*- # Run from the command window (Run as Administrator!): # python registerPython.py # script to register Python 2.0 or later for use with win32all # and other extensions that require Python registry settings # # written by Joakim Löw for Secret Labs AB / PythonWare # # source: # http://www.pythonware.com/products/works/articles/regpy20.htm import sys from _winreg import * # tweak as necessary version = sys.version[:3] installpath = sys.prefix installpath = "D:\Program Files\Python36" # 注意這裏是python安裝路徑 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_LOCAL_MACHINE, regpath) except EnvironmentError: try: print("No Key Found, attempting to register") reg = CreateKey(HKEY_LOCAL_MACHINE, 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()
我在裝pywin32的時候出現個很蛋疼的狀況,我先下載了64位的,安裝提示'python 3.6-32'註冊表未找到,試了下裝32位的居然成功了(明顯是不能用,蛋碎一地-,-)。xml
後來發現問題,64位的提示的是‘Python 3.6-32’,有沒有發現什麼? ‘36-32’!!!so,我把註冊表裏python下面的3.6直接更名成3.6-32,安裝成功...htm
三、安裝pip
常識,很少說了,上篇有提到
四、安裝pyOPENSSL
在Windows下,是沒有預裝pyOPENSSL的
安裝地址:https://launchpad.net/pyopenssl
(能夠直接pip安裝,但版本不必定新,若是不行再上官網)
五、安裝lxml
解析XML的庫,很強大,作爬蟲BS4,selenium,XPATH都會用到
直接pip安裝
pip install lxml
六、安裝Twisted
這個其實在安裝Scrapy的時候會自動安裝,可是他須要visual C++ Build Tools 2015,無奈網速不給力實在下不下來,因此本身安裝了
網址:http://www.lfd.uci.edu/~gohlke/pythonlibs/,這裏是已經編譯好的,能夠直接pip安裝(須要wheel)
七、安裝Scrapy
終於在最後一步,折騰了一夜....
pip install Scrapy
so easy 是否是=.=
pip 會另外下載其餘依賴的包,這些就不要咱們手動安裝啦,等待一會,大功告成!
最後驗證一下,命令行下輸入:Scrapy
打完收功==!
