General Usage
1

First of all, I’ll follow Julia’s instructions CPLEX.jl Add environment statement in

ENV["CPLEX_STUDIO_BINARIES"] = "C:/IBM/CPLEX_Studio128/cplex/bin/x64_win64"

The error report is as follows

ERROR: Failed to precompile CPLEX [a076750e-1247-5638-91d2-ce28b192dca0] to C:\Users\61940\.juliapro\JuliaPro_v1.4.2-1\compiled\v1.4\CPLEX\QpT0w_qertE.ji.
