错误建筑大象鸟

Question

我试图建立Twitter的大象鸟包，所以我可以用猪用它，但我得到一个错误：

这里是我的系统行家信息：

Apache Maven 3.0.3 (r1075438; 2011-02-28 09:31:09-0800) 
Maven home: /usr/share/maven

Default locale: en_US, platform encoding: UTF-8 
OS name: "mac os x", version: "10.8.3", arch: "x86_64", family: "mac" 

我已经安装了Thrift和protobuf。

编辑根据Jigar的建议，我修复了这里遇到的第一个与protobuf版本有关的构建错误。我还更新了导致错误的pom文件中Thrift的版本号。由于错误信息表明

Answer 1

：

Protobuf installation version does not match Protobuf library version

您正在使用协议缓冲区错误的版本，但我仍然得到下面的错误。 @ jigar-joshi发布了一个指针，告诉你如何将其更改为正确的版本。

编辑：以下回答用户报告的新错误。

请务必阅读错误信息并尝试理解它们。例如，这个人说：

/Users/evanzamir/Pig/pig-jars/elephant-bird/core/src/main/java/org/apache/thrift/Fixtures.java:[118,69] error: cannot find symbol

它的意思是，在文件Fixtures.java，在线路118（字69）你有一个符号（例如，变量或方法名）尚未以前定义（或正确导入/合格）。

Answer 2

我有同样的问题，并找到解决方法。你需要安装protobuf 2.4.1和thrift 0.7.0。我已经创建了演示文稿，并遵循一些步骤（关于如何安装旧版本）。希望这将有助于
