我正在尝试构建 Twitter 的大象鸟包，以便可以将其与 Pig 一起使用，但出现错误：

这是我的系统的 Maven 信息：

我已经安装了 Thrift 和 protobuf。

编辑按照 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 文件中的 Thrift 版本号。但我仍然收到以下错误：

如错误消息所示：

Protobuf 安装版本与 Protobuf 库版本不匹配

您使用了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：以下回答用户报告的新错误。

阅读错误消息并尝试理解它们很重要。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的第 118 行（字符 69）中，您有一个先前未定义（或正确导入/正确限定）的符号（例如，变量或方法名称）。

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。我已经创建了演示文稿，其中包含要遵循的步骤（关于如何安装旧版本）。希望这会有所帮助
