Julia中ExcelFiles、Plots与JuMP包预编译失败求助

Hey there, sorry to hear you're stuck with this precompile error while setting up JuMP—let's work through some practical fixes to get you back on track:

• Clear corrupted precompile caches
  Leftover broken cache files are a common culprit here. First, remove JuMP entirely and run Julia's garbage collector to wipe residual files:

  using Pkg
  Pkg.rm("JuMP")
  Pkg.gc()
  

  Restart Julia after this, then try reinstalling JuMP with Pkg.add("JuMP") again.

• Confirm Julia version compatibility
  JuMP has specific version requirements for Julia. Since you're on v1.7, try installing a explicitly compatible version of JuMP to avoid mismatches:

  Pkg.add(name="JuMP", version="1.10")
  

  (Version 1.10 is verified to work smoothly with Julia 1.7—adjust if you need a newer release that still supports your Julia version.)

• Test in a clean temporary environment
  Conflicts with other packages like ExcelFiles or Plots might be causing the failure. Create an isolated temporary environment to test JuMP installation alone:

  using Pkg
  Pkg.activate("--temp")
  Pkg.add("JuMP")
  using JuMP
  

  If this works, the issue lies with your main environment's dependencies. You can then gradually add other packages to the temp environment to pinpoint which one is conflicting.

• Get detailed precompile error logs
  The generic error message doesn't show the root cause. Run a verbose precompile to see exactly what's breaking:

  using Pkg
  Pkg.precompile("JuMP"; verbose=true)
  

  Look for specific error lines (like missing sub-dependencies or syntax issues in a related package) to target your fix more precisely.

• Check system write permissions
  The error references writing to C:\Users\yobbi\.julia\compiled\v1.7\JuMP. If Julia doesn't have proper write access to this folder, precompile will fail. Try launching Julia as an administrator, then repeat the installation steps.
