haystack v2.0.0-beta，pyelasticsearch 0.0.6。当我尝试运行 "python managy rebuid_index" 时，出现错误：

File "/usr/lib/python2.6/site-packages/pyelasticsearch-0.0.6-py2.6.egg/pyelasticsearch.py", line 266, in bulk_index
response = self._send_request('POST', path, body, {'op_type':'create'}, prepare_body=False)

TypeError：_send_request() 得到了一个意外的关键字参数“prepare_body”

pyelasticsearch.py​​ 中的详细信息：

#+
    def bulk_index(self, index, doc_type, docs, id_field="id"):
        """
        Indexes a list of documents as efficiently as possible.
        """
        body_bits = []

        if not len(docs):
            raise ElasticSearchError("No documents provided for bulk indexing!")

        for doc in docs:
            action = {"index": {"_index": index, "_type": doc_type}}

            if doc.get(id_field):
                action['index']['_id'] = doc[id_field]

            body_bits.append(self._prep_request(action))
            body_bits.append(self._prep_request(doc))

        path = self._make_path(['_bulk'])
        # Need the trailing newline.
        body = '\n'.join(body_bits) + '\n'
        response = self._send_request('POST', path, body, {'op_type':'create'}, prepare_body=False)
        return response
#+

实际上，我自己添加了 bulk_index，在错误“ self.conn.bulk_index(self.index_name, 'modelresult', prepped_docs, id_field=ID) AttributeError: 'ElasticSearch' object has no attribute 'bulk_index'”之后，点击链接https://github.com/toastdriven/pyelasticsearch/blob/master/pyelasticsearch.py ​​#L424-469 有人有同样的经历吗？任何建议和参考将不胜感激。
