##windows7 安裝 Scrapy##
1.打開cmd.exe輸入指令:
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,檢視是否已經安裝好pip
C:\Users\admin>pip
a. 沒有就去下載下傳pip
網址如下:https://pypi.python.org/pypi/pip#downloads
下載下傳這個壓縮包:pip-9.0.1.tar.gz (md5, pgp)
b. 解壓到指定目錄,進入pip-9.0.1目錄,輸入此指令
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
下載下傳這個壓縮包:setuptools-38.5.2.zip (md5)
f. 解壓到指定目錄,進入setuptools-38.5.2目錄,輸入此指令
python setup.py install

C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
網址:https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
h. 下載下傳二選一:
Twisted‑17.9.0‑cp36‑cp36m‑win_amd64.whl(看系統位數下載下傳)
Twisted‑17.9.0‑cp36‑cp36m‑win32.whl(看系統位數下載下傳)
C:\Users\admin>pip install Scrapy
