本地计算机上的Pig错误

我是一个新手，如果这个问题看起来很愚蠢，请原谅我。我已经安装了hadoop 1.2.1，并且基本的wordcount示例在我的本地环境下工作正常，因此在下一阶段的探索中，我安装了Pig 0.13.0。

当我刚尝试运行pig -help时，它似乎工作正常。但是当我运行Pig版本时，出现如下所示的IOException：

14/08/06 01:00:08 INFO pig.ExecTypeProvider: Trying ExecType : LOCAL
14/08/06 01:00:08 INFO pig.ExecTypeProvider: Trying ExecType : MAPREDUCE

日志文件的内容如下：

java.io.FileNotFoundException: File version does not exist.

如果有人可以帮助我了解需要解决的问题，那就太好了。
