1.打開cmd.exe輸入命令:

    C:\Users\admin>python
    先看是否已經安裝python,沒有就安裝python,此處省略安裝python。

2.假設已經安裝有python,查看是否已經安裝好pip

    C:\Users\admin>pip

a. 沒有就去下載pip

    網址如下:https://pypi.python.org/pypi/pip#downloads
    下載這個壓縮包:pip-9.0.1.tar.gz (md5, pgp)

b. 解壓到指定目錄,進入pip-9.0.1目錄,輸入此命令

    python setup.py install

c. 如果出現以下錯誤:

    Traceback (most recent call last):  
      File "setup.py", line 31, in <module>  
        from setuptools import setup, find_packages  
    ImportError: No module named setuptools  

d. 就安裝setuptools:

    網址:https://pypi.python.org/pypi/setuptools
    下載這個壓縮包:setuptools-38.5.2.zip (md5)

f. 解壓到指定目錄,進入setuptools-38.5.2目錄,輸入此命令

    python setup.py install

g. 如果出現以下錯誤:

    running build_ext
        building ‘twisted.test.raiser‘ extension
        error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual
    C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

    網址:https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted

h. 下載二選一:
            Twisted?17.9.0?cp36?cp36m?win_amd64.whl(看系統位數下載)
            Twisted?17.9.0?cp36?cp36m?win32.whl(看系統位數下載)

3.安裝scrapy

    C:\Users\admin>pip install Scrapy
    成功後提示:
    Installing collected packages: Scrap
    Successfully installed Scrapy-1.5.0

4.如果運行scapy crawl quotes【quotes是項目名字】報錯,就安裝pypiwin32

     C:\Users\admin>pip install pypiwin32

5.再次運行就會成功
