python scrapy 不工作 - "ImportError: No module named settings"

Question

/usr/lib/python2.7/site-packages/scrapy 中的 scrapy 库
我的项目目录:

.../projects/scrapy                                       
.../projects/parser_module                                     
....../projects/parser_module/parser  
....../projects/parser_module/parser           
........../projects/parser_module/parser/spiders/.....     
........../projects/parser_module/parser/<files etc>   
....../projects/parser_module/scrapy.cfg

在目录 .../projects/parser_module/ 我设置命令 scrapy crawl parser 并得到结果:

Traceback (most recent call last):                                                                   

 File "/usr/bin/scrapy", line 4, in <module>                                                         
   execute()                                                                                         
  File "/usr/lib/python2.7/site-packages/scrapy/cmdline.py", line 109, in execute  
  settings = get_project_settings() 
  File "/usr/lib/python2.7/site-packages/scrapy/utils/project.py", line 60, in get_project_settings  
    settings.setmodule(settings_module_path, priority='project')          
  File "/usr/lib/python2.7/site-packages/scrapy/settings/__init__.py", line 108, in setmodule        
    module = import_module(module)                                                                   
  File "/usr/lib64/python2.7/importlib/__init__.py", line 37, in import_module                       
    __import__(name)                                                                                 
ImportError: No module named settings  

你能告诉我如何解决这个问题吗？

Answer 1

为避免此类问题，请使用 scrapy startproject parser_module 创建您的项目文件夹

现在要解决您的问题，您要么重新开始，要么使用 scrapy startproject 创建一个虚拟项目以从中复制 setting.py。然后也许下一个错误你会在这个文件夹中找到其他丢失的文件。

这是scrapy项目的典型结构。
