這篇文章主要介紹了Pyinstaller打包Scrapy項目的實現(xiàn)步驟，文中通過示例代碼介紹的非常詳細，對大家的學習或者工作具有一定的參考學習價值，需要的朋友們下面隨著小編來一起學習學習吧

1.安裝pyinstaller http://chabaoo.cn/article/177160.htm

2.安裝pywin32 http://chabaoo.cn/article/187388.htm

3.安裝其他模塊

注意點:

scrapy用pyinstaller打包不能用

cmdline.execute('scrapy crawl douban -o test.csv --nolog'.split())

我用的是CrawlerProcess方式來輸出

舉個栗子：

1、在scrapy項目根目錄下建一個crawl.py(你可以自己定義)如下圖

cralw.py代碼如下

# -*- coding: utf-8 -*-
from scrapy.crawler import CrawlerProcess
from scrapy.utils.project import get_project_settings
from douban.spiders.douban_spider import Douban_spider

#打包需要的import
import urllib.robotparser
import scrapy.spiderloader
import scrapy.statscollectors
import scrapy.logformatter
import scrapy.dupefilters
import scrapy.squeues
import scrapy.extensions.spiderstate
import scrapy.extensions.corestats
import scrapy.extensions.telnet
import scrapy.extensions.logstats
import scrapy.extensions.memusage
import scrapy.extensions.memdebug
import scrapy.extensions.feedexport
import scrapy.extensions.closespider
import scrapy.extensions.debug
import scrapy.extensions.httpcache
import scrapy.extensions.statsmailer
import scrapy.extensions.throttle
import scrapy.core.scheduler
import scrapy.core.engine
import scrapy.core.scraper
import scrapy.core.spidermw
import scrapy.core.downloader
import scrapy.downloadermiddlewares.stats
import scrapy.downloadermiddlewares.httpcache
import scrapy.downloadermiddlewares.cookies
import scrapy.downloadermiddlewares.useragent
import scrapy.downloadermiddlewares.httpproxy
import scrapy.downloadermiddlewares.ajaxcrawl
import scrapy.downloadermiddlewares.chunked
import scrapy.downloadermiddlewares.decompression
import scrapy.downloadermiddlewares.defaultheaders
import scrapy.downloadermiddlewares.downloadtimeout
import scrapy.downloadermiddlewares.httpauth
import scrapy.downloadermiddlewares.httpcompression
import scrapy.downloadermiddlewares.redirect
import scrapy.downloadermiddlewares.retry
import scrapy.downloadermiddlewares.robotstxt
import scrapy.spidermiddlewares.depth
import scrapy.spidermiddlewares.httperror
import scrapy.spidermiddlewares.offsite
import scrapy.spidermiddlewares.referer
import scrapy.spidermiddlewares.urllength
import scrapy.pipelines
import scrapy.core.downloader.handlers.http
import scrapy.core.downloader.contextfactory

from douban.pipelines import DoubanPipeline
from douban.items import DoubanItem
import douban.settings

if __name__ == '__main__':
  setting = get_project_settings()
  process = CrawlerProcess(settings=setting)
  process.crawl(Douban_spider)
  process.start()

2、在crawl.py目錄下pyinstaller crawl.py 生成dist，build（可刪）和crawl.spec（可刪）。

3、在crawl.exe目錄下創(chuàng)建文件夾scrapy，然后到自己安裝的scrapy文件夾中把VERSION和mime.types兩個文件復制到剛才創(chuàng)建的scrapy文件夾中。

4、發(fā)布程序包括douban/dist 和douban/scrapy.cfg

如果沒有scrapy.cfg無法讀取settings.py和pipelines.py的配置
