因为我想用象鸟在 PIG 中读/写 JSON 文件，所以下载了 EB for Mac

git clone git://github.com/kevinweil/elephant-bird.git

并尝试使用

mvn package

并且构建失败如下，

我已经检查了这个链接ElephantBird package build failure:并下载了 thrift 0.9 并尝试在 pom.xml 中指定绝对路径

请就如何运行它提出任何建议。

如果您使用的是基于 apt-get 的系统，请尝试安装该libprotobuf-java软件包。您还可以从源http://code.google.com/p/protobuf/downloads/detail?name=protobuf-2.4.1.tar.gz安装 2.4.1 版。

https://github.com/kevinweil/elephant-bird/wiki/Build-errors提到了这个错误。
