Question

我正在尝试建立Twitter的大象鸟包，所以我可以将它与Pig一起使用，但我收到了一个错误：

以下是我系统的maven信息：

Apache Maven 3.0.3 (r1075438; 2011-02-28 09:31:09-0800)

我已经安装了Thrift和protobuf。

编辑根据Jigar的建议，我修复了此处遇到的与protobuf版本有关的第一个构建错误。我还更新了导致错误的pom文件中Thrift的版本号。但我仍然收到以下错误：

Answer 1

如错误消息所示：

Protobuf安装版本与Protobuf库版本
不匹配

您使用的是错误版本的协议缓冲区。 @ jigar-joshi发布了一个指针，向您展示如何将其更改为正确的版本。

编辑：以下内容回答了用户报告的新错误。

阅读错误消息并尝试理解它们非常重要。例如，这个说：

/Users/evanzamir/Pig/pig-jars/elephant-bird/core/src/main/java/org/apache/thrift/Fixtures.java:[118,69]错误：找不到符号

这意味着在文件Fixtures.java中，在第118行（字符69）中，您有一个先前未定义的符号（例如，变量或方法名称）（或正确导入/正确限定））。

Answer 2

我遇到了同样的问题并找到了解决方法。你需要安装protobuf 2.4.1和thrift 0.7.0。我创建了演示文稿，其中包含要遵循的步骤（如何安装旧版本）。希望这会有所帮助
