Pyinstaller打包Scrapy项目的实现步骤

1.安装pyinstaller https://www.jb51.net/article/177160.htm

2.安装pywin32 https://www.jb51.net/article/187388.htm

3.安装其他模块

注意点:

scrapy用pyinstaller打包不能用

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

我用的是CrawlerProcess方式来输出

举个栗子：

1、在scrapy项目根目录下建一个crawl.py(你可以自己定义)如下图

cralw.py代码如下

# -*- 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目录下pyinstaller crawl.py 生成dist，build（可删）和crawl.spec（可删）。

3、在crawl.exe目录下创建文件夹scrapy，然后到自己安装的scrapy文件夹中把VERSION和mime.types两个文件复制到刚才创建的scrapy文件夹中。

4、发布程序包括douban/dist 和douban/scrapy.cfg

如果没有scrapy.cfg无法读取settings.py和pipelines.py的配置

5、在另外一台机器上测试成功

6、对于自定义的pipelines和settings，貌似用pyinstaller打包后的 exe无法读取到settings和pipelines，哪位高手看看能解决这个问题？？？
