NativeLibraryDarwin.java:64 - 无法将 C 库链接到 JNA。原生方法将不可用

Question

如果您使用的是配备 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：

1. 找到 jna- 在哪里。.*.jar 位于。你可以使用 find /opt/homebrew/ -name '*.jar' | grep cassandra
2. 浏览到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。
3. 替换你的 jna- . .*.jar 文件与您下载的文件一起。就我而言，我替换了 jna-5.6.0.jar。请记住将文件名保留为以前的文件名。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

4. 重新启动卡桑德拉

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。

要解决此问题，请前往 JNA GitHub 存储库的“下载”部分，您应该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jna-5.6.0.jarCassandralib/目录中的现有文件（基于 tarball 的安装）。
