I am trying to install and use python solidity parser by ConsenSys
I keep on getting the following error
File "<stdin>", line 1, in <module>
File "/home/seed/.local/lib/python3.5/site-packages/python-solidity-parser/solidity_parser/__init__.py", line 1, in <module>
from .parser import parse_file, parse, objectify, visit
File "/home/seed/.local/lib/python3.5/site-packages/python-solidity-parser/solidity_parser/parser.py", line 10, in <module>
from solidity_parser.solidity_antlr4.SolidityLexer import SolidityLexer
File "/home/seed/.local/lib/python3.5/site-packages/python-solidity-parser/solidity_parser/solidity_antlr4/SolidityLexer.py", line 783, in <module>
class SolidityLexer(Lexer):
NameError: name 'Lexer' is not defined
Is there any other dependency that we are supposed to install that I missed? I am running this on ubuntu with python 3.5.2
