Elephant bird构建失败

Question

由于我想使用Elephant bird在PIG中读/写JSON文件，因此下载了用于Mac的EB

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

，并尝试使用

mvn package

构建失败，如下所示：

[INFO] --- protobuf-maven-plugin:0.4:run (default) @ elephant-bird-core ---
[INFO] Protobuf dependency version 2.4.1

[ERROR] Failed to execute goal com.github.igor-petruk.protobuf:protobuf-maven-plugin:0.4:run (default) on project elephant-bird-core: Unable to find 'protoc' -> [Help 1]

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

如果有任何建议，请告诉我如何让它运行起来。

如果您使用的是基于apt-get的系统，请尝试安装libprotobuf-java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。
