NativeLibraryDarwin.java:64 - 无法针对 JNA link C 库。本机方法将不可用

Question

如果您正在使用配备 M1 芯片的最新 MacBook pro。安装 Cassandra 并启动它可能会引发错误。

步骤 1：安装Jdk8 2: 安装 Cassandra 4.0.1

如何开始：/opt/homebrew/opt/cassandra/bin/cassandra -f

输出：

ERROR [main] 2021-10-08 00:03:12,568 NativeLibraryDarwin.java:64 - Failed to link the C library against JNA. Native methods will be unavailable.

Answer 1

解决方案：

查找 jna-..*.jar 所在的位置。你可以使用 find . -name '*.jar' | grep cassandra
浏览至 https://search.maven.org/artifact/net.java.dev.jna/jna/5.8.0/jar 并从页面右上角的下载按钮下载 jar。
将您的 jna-..*.jar 文件替换为您下载的文件。在我的例子中，我替换了 jna-5.6.0.jar。请记住将文件名保留为您以前的文件名。示例我移动了 jna-5.8.0.jar 并重命名为 jna-5.6.0.jar

mv /Users/mansooralikhan/Downloads/jna-5.8.0.jar /opt/homebrew/Cellar/cassandra/4.0.1/libexec/jna-5.6.0.jar

Answer 2

为了回应 Mansoor 的回答，我要补充一点，不幸的是，Apache Cassandra 4.0 附带的 JNA 版本与 M1 架构不兼容。

要解决这个问题，请前往 JNA GitHub 存储库的“下载”部分，您应该可以在其中找到最新版本的 JNA jar 文件。

https://github.com/java-native-access/jna#jna

下载 JNA 5.8 或更高版本，并替换 Cassandra 的 lib/ 目录中现有的 jna-5.6.0.jar 文件（基于 tarball 的安装）。

Answer 3

只是为了补充这里的答案，我想为后代注意，JNA 5.6.0 不支持的 Apple M1 设备上的 arm64 问题之前已在 Apache Cassandra 项目中提出。

最近，CASSANDRA-17019 报道了它。我在项目 devs/contributors 中提出了它，希望它能尽快得到审查和解决。干杯！
