Python 2.7 - JavaError when using grammar-check 1.3.1 library -


i trying use grammar-check 1.3.1 library python

i have installed using pip commands

$ pip install --upgrade 3to2  $ pip install --upgrade language-check

i unzipped languagetool file this link , moved c:\users\me\appdata\roaming\python\python27\site-packages\grammar_check

then tried run test program

import grammar_check gc  open("file.txt") f:     tool = gc.languagetool('en-us')     matches = tool.check(f.read())     print len(matches)

but got error

file "lang-grammar-checker.py", line 22, in main tool = gc.languagetool(predicted) file "c:\users\me\appdata\roaming\python\python27\site-packages\grammar_check\__init__.py", line 190, in __init__ self._start_server_on_free_port() file "c:\users\me\appdata\roaming\python\python27\site-packages\grammar_check\__init__.py", line 318, in _start_server_on_free_port cls._start_server() file "c:\users\me\appdata\roaming\python\python27\site-packages\grammar_check\__init__.py", line 330, in _start_server server_cmd = get_server_cmd(cls._port) file "c:\users\me\appdata\roaming\python\python27\site-packages\grammar_check\__init__.py", line 541, in get_server_cmd java_path, jar_path = get_jar_info() file "c:\users\me\appdata\roaming\python\python27\site-packages\grammar_check\__init__.py", line 554, in get_jar_info raise javaerror(u"can't find java") grammar_check.javaerror: can't find java

i have java8 installed in computer. how can solve error?

the problem system can't see java. can check if system "knows" java typing: 

java -version

in command prompt (without going java location!). can adding environment variable path java development kit location. how set or change path system variable?
