Mac OS X下使用JPype启动JVM提示文件不存在但实际存在的问题求助

问题场景 #

在Mac OS X 13.2.1系统下，使用Python 3.10.4及JPype1 1.4.1尝试启动JVM，手动指定JVM路径为/Library/Java/JavaVirtualMachines/microsoft-11.jdk/Contents/Home/lib/jli/libjli.dylib，运行代码时提示该文件不存在。

代码片段 #

import jpype

jvm_path = "/Library/Java/JavaVirtualMachines/microsoft-11.jdk/Contents/Home/lib/jli/libjli.dylib"

jpype.startJVM(
    jvm_path,
    classpath=['~/org.alloytools.alloy.dist.jar'],
)

错误信息 #

解决方向 #

• 验证指定路径的文件是否存在：在终端执行ls /Library/Java/JavaVirtualMachines/microsoft-11.jdk/Contents/Home/lib/jli/libjli.dylib，若返回文件不存在，说明路径错误。
• 替换为正确的JVM动态库路径：Mac上OpenJDK 11的标准JVM库路径为/Library/Java/JavaVirtualMachines/microsoft-11.jdk/Contents/Home/lib/server/libjvm.dylib，将代码中的jvm_path替换为此路径重试。
• 让JPype自动探测JVM路径：删除手动指定的jvm_path参数，直接调用jpype.startJVM(classpath=['/Users/<username>/org.alloytools.alloy.dist.jar'])，JPype会自动查找系统默认JDK。
• 修正classpath路径：代码中~/org.alloytools.alloy.dist.jar的波浪号不会被JPype解析，替换为绝对路径（如/Users/<username>/org.alloytools.alloy.dist.jar）。
• 确认架构一致性：确保Python和JDK都是64位（当前环境已满足，可快速排除此问题）。
