Apple Silicon芯片下ChakraCore引擎加载问题求解

错误日志 #

Engine name: ChakraCoreJsEngine
Engine version: Nov 11, 2021
Category: Engine load error
Description: Most likely it happened, because the 'libChakraCore.dylib' assembly or one of its dependencies was not found. There is no JavaScriptEngineSwitcher.ChakraCore.Native.osx-* package for the arm64 processor architecture. You can build the 'libChakraCore.dylib' assembly for the current processor architecture by using instructions from the official repository. ---> System.DllNotFoundException: Unable to load shared library 'ChakraCore' or one of its dependencies. In order to help diagnose loading problems, consider setting the DYLD_PRINT_LIBRARIES environment variable: dlopen(libChakraCore, 0x0001): tried: 'libChakraCore' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibChakraCore' (no such file), '/usr/lib/libChakraCore' (no such file, not in dyld cache), 'libChakraCore' (no such file), '/usr/local/lib/libChakraCore' (not a file), '/usr/lib/libChakraCore' (no such file, not in dyld cache)

解决方案建议 #

• 自行编译arm64架构的libChakraCore.dylib：

  1. 拉取ChakraCore仓库的最新代码，尽管官方Wiki停更，但社区可能有适配Apple Silicon的提交
  2. 在Apple Silicon设备上使用Xcode命令行工具，执行编译流程时指定arm64架构，生成适配本地芯片的动态库
  3. 将编译后的libChakraCore.dylib放置到项目可加载的路径，比如项目根目录、系统库路径，或通过配置指定加载位置

• 替换为兼容Apple Silicon的JS引擎：
  选择已有官方arm64预编译包的引擎（如V8、QuickJS），通过JavaScriptEngineSwitcher切换至对应引擎，无需自行编译适配

• 启用Rosetta 2兼容模式：
  对运行程序开启Rosetta 2兼容，让应用以x86_64架构运行，可直接使用现有x86版本的ChakraCore库，但会带来一定性能损耗
