我曾尝试安装libssl-dev，但brew install找不到libssl-dev

Answer 1

我在macOS上编译Hadoop本机lib时也遇到了这个问题。解：

1. 打开发生错误的文件build-main.xml：

   vim /Users/wanwenqing/Hadoop/hadoop-2.7.2-src/hadoop-tools/hadoop-
   pipes/target/antrun/build-main.xml

2. 找到错误行并执行： cmake /Users/wanwenqing/Hadoop/hadoop-2.7.2-src/hadoop-tools/hadoop-pipes/src/ -DJVM_ARCH_DATA_MODEL = 64 然后您将看到错误的具体原因： Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the System variable OPENSSL_ROOT_DIR (missing: OPENSSL_INCLUDE_DIR), suggesting that not found openssl suggested that the need to add environment variables
3. 所以添加这些System变量： export OPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2k（注意这是openssl安装目录，我使用brew安装openssl） export OPENSSL_INCLUDE_DIR=/usr/local/Cellar/openssl/1.0.2k/include 然后再次执行： cmake /Users/wanwenqing/Hadoop/hadoop-2.7.2-src/hadoop-tools/hadoop-pipes/src/ -DJVM_ARCH_DATA_MODEL = 6

如果没有错误，您可以重新运行maven编译器命令来构建hadoop native lib。
