Pyinstaller packaging scene

First installation pyinstaller

pip install pyinstaller

The effect we want : Click on EXE file , And then run scrapy Program , Which is running EXE It's time to execute this order scrapy crawl Reptile name

The first way ( It doesn't seem to work , But it's easy to think of )

1. scrapy Provides a module cmdline, We can start with scrapy Project scrapy.cfg Under the same category , Create a crawl.py file , It writes crawler commands

   from scrapy import cmdline
   cmdline.execute("scrapy crawl  name ".split())
   

2. And then use pyinstaller package

   pyinstaller crawl.py
   

3. Click on the run EXE file , stay dist/crawl, Delete appears , There should be an error , We can EXE Drag the file into cmd Inside , In this way, you can check the errors , Anyway, there have been various mistakes , Not solve , I gave up this method .

The second way ( recommend )

Official documents

1. Also in crawl.py Write code in the file , But the code is different

   from scrapy.crawler import CrawlerProcess
   from scrapy.utils.project import get_project_settings
   
   process = CrawlerProcess(get_project_settings())
   
   process.crawl('scientist')
   process.start()
   

2. And then use pyinstaller package

   pyinstaller crawl.py
   

3. function EXE Flash back , It should be a mistake , Drag directly into cmd, Found an error xxx Module does not exist , You can have a look dist/crawl Is there less module inside , It is found that there is really no such module , Then we can go Python Copy one from the environment .
   

4. Then run it again
