我一直在尝试从.bat文件中运行一只刮破的蜘蛛
当我运行包含以下文本的.bat文件时:
@echo off
REM activate Python venv
CALL "D:\python\scrapy_projects\venv\Scripts\activate.bat"
CD "D:\python\scrapy_projects\digikalasellerdata\digikalasellerdata\spiders"
CALL "D:\python\scrapy_projects\venv\Scripts\python.exe" "
运行OSX10.9.4时,我尝试使用Scrapy,但我得到了以下错误:
Traceback (most recent call last):

我正在尝试在Mac OS X El Capitan上使用Scrapy。我已经安装了zsh,并且我已经尝试了所有我可以在网上找到的解决这个问题的方法。我也看过,但无法解决我的问题!
通过brew安装Python并添加"pip install scrapy":

/usr/local/bin/python
我的.zshrc有下面这一行:
export PATH=/usr/local/bin:$PATH
export PYTHONPATH="/Library/Python/2.7/site-packages"
这是我
环境Windows 7 (64) Python 2.7.3 (32) pip安装scrapy

安装完所有的依赖库(lxml,openssl,pywin32,twisted,zope)后,当我通过pip安装scrapy时,我再也不会得到错误了,所以一切似乎都是按需安装的。
问题:
如果我尝试从python目录开始
C:\Python27> scrapy startproject new
'scrapy' is not recgonized as an internal command or ext
通过pip安装Scrapy之后,并拥有Python 2.7.10

我问了一个新的问题,因为我意识到我在上一个问题中不够清楚。我正在尝试学习scrapy教程,但我被困在了关键的一步,"scrapy crawl dmoz“命令。代码如下(我已经在python shell中编写了该命令,并将其保存为输入.py扩展名):
