VScode Julia REPL "path" issue (while bash works fine)

Hi all,

I’m trying to use the Julia REPL but having a library path problem.
Oddly, the same code works just fine with bash/terminal (right-hand side), but an error occurs with REPL (left-hand side):
Can anyone let me know how to resolve this issue?

Here is the simple JuMP code (test_Gurobi.jl) :

using JuMP, Gurobi
m = Model(Gurobi.Optimizer)
@variable(m, x <= 5)
@objective(m, Max, x)
JuMP.optimize!(m)
@show JuMP.termination_status(m)

and here is my environment:

Are these using the same environment? What happens if you import Pkg; Pkg.build("Gurobi") in the REPL before running the script?

Otherwise I’m not sure what the problem is. VS Code is probably mangling things on their side.

cc @davidanthoff may have insight.

@odow Thank you for your reply. Yes, I have only one Julia version installed on my mac.

Here is what I get when I ran Pkg.build("Gurobi") on the VScode Julia REPL:

julia> Pkg.build("Gurobi")

**Unable to locate Gurobi installation. Running some common diagnostics.**

Gurobi.jl only supports the following versions:

 - gurobi91
 - gurobi90

Did you download and install one of these versions from gurobi.com?
Installing Gurobi.jl via the Julia package manager is _not_ sufficient!

As a matter of fact, it is not only GUROBI but also Ipopt+HSL. They work well on the bash terminal, but VScode REPL returns an error message (e.g. dlopen(libhsl.dylib, 2): image not found).

Following up on this issue:

I just found out that, Julia REPL enters a different environment as soon as I start it by (cmd + shift + p -> Julia: Start REPL). Then it is on “(directory name)” environment, not “(@v1.6)”

On Julia REPL, if I type ] and status, then:

(JuMP_examples) pkg> status
      Status `~/Dropbox/Julia/JuMP_examples/Project.toml` (empty project)

On regular terminal, if I type ] and status, then:

(@v1.6) pkg> status
