[Python] python scrapy does not working - "ImportError: No module named settings"

scrappy lib in /usr/lib/python2.7/site-packages/scrapy
my project catalog:

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

In directory .../projects/parser_module/ I am set command scrapy crawl parser and get result:

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
