Get empty paths when use converter

[t-walker-wei]

Environment: Python 3.5.2 Ubuntu16.04LTS.
The shp file I download from: http://www.naturalearthdata.com/
Json config file:

[{
    "name": "read_data",
    "file_name": "ne_110m_admin_0_countries_lakes/ne_110m_admin_0_countries_lakes.shp",
    "longitude0": 11.5
  },{
    "name": "write_data",
    "format": "jvectormap",
    "file_name": "origin-world.js",
    "params": {
      "code_field": "ISO_A2",
      "name_field": "NAME",
      "name": "world"
    }
  }]

Out put in origin-world.js :
jQuery.fn.vectorMap('addMap', 'world_merc',{"height": 779.9122978262657, "projection": {"centralMeridian": 11.5, "type": "merc"}, "width": 900.0, "paths": {}, "insets": [{"height": 779.9122978262657, "bbox": [{"x": -20004297.15152583, "y": -18449355.690353}, {"x": 20026572.394749388, "y": 16240163.70055698}], "left": 0, "width": 900, "top": 0}]});
The paths attribute is empty.
Do somebody have any ideas?
Thx.

I should solved it.I flow the document and use script processor.py
Change

jvectormap/converter/processor.py

Line 13 in 1a905c8

from booleano.parser import Grammar, EvaluableParseManager, SymbolTable, Bind

to

from booleano.parser import Grammar, SymbolTable, Bind
from booleano.parser.core EvaluableParseManager

If have import EvaluableParseManager issue .
For the empty paths issue, because the Python3 filter() / map() function return a filter object / map object instead of list. After iteration, the pointer will go the end of the object. My solution is convert the filter / map object to list.
Example:
After

jvectormap/converter/processor.py

Line 163 in 1a905c8

geometries = filter(lambda g: g.properties[self.config['code_field']] in codes, data_source.geometries)

add line:
geometries = list(geometries)

And, I should try the converter.py.It would be better have document for how to use script converter.py
