我尽量不寻求帮助并自己解决，但这非常困难，我无法弄清楚如何解决它。我正在使用 Python 2.7 和 Django 1.4。我使用 Tomcat 7.0 和 Solr 作为 Haystack v2 beta 的后端。我安装了 Pysolr v 3。Apache Tomcat 服务运行正常，我可以去 127.0.0.1:8000/solr/admin。我运行 manage.py build_solr_schema 并将该 schema.xml 文件放入我的 C:\solr\conf 文件夹中。

作为最后一步，我想运行 manage.py rebuild_index。当我在命令提示符中键入并单击 Enter 时，我会收到通常的消息：

WARNING: This will irreparably remove EVERYTHING from your search index in connection 'default'.
Your choices after this are to restore from backups or rebuild via the `rebuild_index` command.
Are you sure you wish to continue? [y/N]

然后，当我输入“y”并再次单击输入时，我得到以下信息：

Removing all documents from your index because you said so.
All documents removed.
Indexing 71 readings.

请帮忙，因为我已经为此苦苦挣扎了一段时间。我已经让这个设置在我的家用电脑上工作，但我工作的电脑性能不佳。非常感谢您提前。

更新到 pysolr 3.0.6 修复了这个问题。

（我知道我参加聚会有点晚了，但无论如何它可能对某人有帮助。）
