1、安裝pywin32

pip install pywin32-220.1-cp35-cp35m-win32.whl

pip install Twisted-16.5.0-cp35-cp35m-win32.whl

3、安裝 scrapy

pip install scrapy

在這一步的安裝中出現以下報錯：

Command "c:\users\springlustre\appdata\local\programs\python\python35-32\python.exe -u -c "import setuptools, tokenize;_
_file__='C:\\Users\\SPRING~1\\AppData\\Local\\Temp\\pip-build-u69illst\\lxml\\setup.py';f=getattr(tokenize, 'open', open
)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record C:\Use
rs\SPRING~1\AppData\Local\Temp\pip-serz1p13-record\install-record.txt --single-version-externally-managed --compile" fai
led with error code 1 in C:\Users\SPRING~1\AppData\Local\Temp\pip-build-u69illst\lxml\

原因是在windows環境中，呼叫的vcvarsall.bat的檔案在c++程式設計環境才會有。網上的解決方法有兩個：一是安裝MinGW；二是安裝Visual Studio ，我用的是第二種

   下載安裝visio studio 

再次安裝報錯

 C:\Users\SPRING~1\AppData\Local\Temp\xmlXPathInit5xdue4a3.c(1): fatal error C1083: 無法開啟包括檔案: “libxml/xpath.

執行命令  pip install lxml

執行的時候 報錯
