我遇到了与这个问题类似的问题:
UnsatisfiedLinkError with sqlite4java Jar on Mac OS X
但是，我在 Mac 上运行，并且我的 lib 文件夹中有相关的库。但是，如果我按原样运行它，我会得到 UnsatisfiedLinkError。如果我运行“java -jar sqlite4java.jar -d”，我会得到以下输出:

我可以看到它正在寻找 sqlite4java-osx-x86_64 库，所以我随后运行了“ln -s libsqlite4java-osx.jnilib libsqlite4java-osx-x86_64.jnilib”和“ln -s libsqlite4java-osx- 10.4.jnilib libsqlite4java-osx-x86_64.jnilib”，这似乎有帮助:

看起来不错，对吧？否。当我尝试运行我的 java 代码时，它在尝试打开数据库时再次失败，并出现 UnsatisfiedLinkError。
有什么明显的我想念的吗？这是我的 lib 目录的相关部分的 ls 作为健全性检查:

最佳答案
这是解决方案:
Exception in thread "main" com.almworks.sqlite4java.SQLiteException:
[-91]cannot load library: java.lang.UnsatisfiedLinkError: no sqlite4java-osx-x86_64
in java.library.path
请尝试运行:
java -jar sqlite4java.jar -d
让它尝试加载二进制文件的所有变体并验证结果。
结果一定是这样的:
java -jar sqlite4java.jar -d

按照从更具体到不太具体的顺序尝试文件。所以顺序是正确的。
问题是没有更具体的二进制文件 - 所以我们可能需要将 libsqlite4java-osx.jnilib 重命名为 libsqlite4java-osx-amd64 .dylib.
