求助：升级Jupyter Notebook后IJulia预编译失败

针对IJulia预编译时触发EXCEPTION_ACCESS_VIOLATION错误、降级版本无效且怀疑与Jupyter升级相关的问题，可按以下步骤尝试修复：

1. 彻底清理预编译缓存 #

• 手动删除IJulia的预编译目录：C:\Users\User\.julia\compiled\v1.9\IJulia
• 或在Julia REPL中执行强制全量预编译：

  using Pkg
  Pkg.precompile(; incremental=false)
  

2. 重新构建IJulia #

清理缓存后，重新构建并预编译IJulia：

using Pkg
Pkg.build("IJulia")
Pkg.precompile("IJulia")

3. 锁定兼容的IJulia版本 #

若Jupyter升级导致版本不兼容，可指定与Julia 1.9匹配的IJulia版本（如1.24.x系列）：

using Pkg
Pkg.rm("IJulia")
Pkg.add("IJulia@1.24.2")
Pkg.build("IJulia")

4. 禁用增量预编译临时修复 #

通过禁用编译模块的方式重新安装IJulia：

1. 打开命令行执行：

   julia --compiled-modules=no
   

2. 在启动的REPL中执行：

   using Pkg
   Pkg.rm("IJulia")
   Pkg.add("IJulia")
   Pkg.precompile("IJulia")
   

5. 修复Julia系统镜像 #

错误日志显示系统镜像恢复失败，可能是Julia安装文件损坏：

• 卸载当前Julia 1.9.0，重新下载官方安装包覆盖安装
• 安装完成后更新所有包：

  using Pkg
  Pkg.update()
  

附错误日志： #
