happybase1.1.0 报错：ThriftPy does not support generating module with path in protocol 'c'

storm里面的python脚本需要读写hbase，在本地运行测试的时候报错：thriftpy.parser.exc.ThriftParserError: ThriftPy does not support generating module with path in protocol 'c'

**原因：happybase1.1.0在win下不支持绝对路径**

具体原因：happybase要读取C:\\ProgramData\\Anaconda3\\Lib\\site-packages\\happybase\\Hbase.thrift，但在C:\\ProgramData\\Anaconda3\\Lib\\site-packages\\thriftpy\\parser\\parser.py中的496行

path是Hbase.thrift的绝对路径（我的是“C:\\ProgramData\\Anaconda3\\Lib\\site-packages\\happybase\\Hbase.thrift”），但经过urlparse(path).scheme后，url\_scheme变成了“c”，（这也就是报错信息中最后的“c”）。根据代码，url\_scheme既不为“”，也不包含   
（‘http’,’https’），则只能为raise报错。   
解决方案：将488行的url\_scheme == ”改为url\_scheme in (‘c’, ”)，即

url_scheme = urlparse(path).scheme
        #if url_scheme == '':
        if url_scheme in ('c', ''):
            with open(path) as fh:
                data = fh.read()
        elif url_scheme in ('http', 'https'):
            data = urlopen(path).read()
        else:
            raise ThriftParserError('ThriftPy does not support generating module '
                                    'with path in protocol \'{}\''.format(
                                        url_scheme))

注：’c’为盘符，就是我把python装在了c盘，只要能让那个判断为真就行。ThriftPy does not support generating module with path in protocol 'd' 或‘e’或'f' 都是同样操作
