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>   
....../projects/parser_module/scrapy.cfg

```

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

```
Traceback (most recent call last):
