Hi,

Just trying to use Julia on the [repl.it](https://repl.it/) website. There you can spin up an instance with Julia 1.3 pre-configured.  
using JuMP in it results in a compilation error.

Is this a known problem? is there a way to make JuMP work in this environment without reinstalling a more recent Julia release?

Thank you!  
Faris

What’s the error? I haven’t tried repl.it; this seems more a question for their support. JuMP works on Julia 1.3.

So I looked at it, and it looks like the underlying precompile error details are not being printed. I’d guess maybe repl.it is discarding the error stream somehow?

```julia

Thank you both.  
Yes, I will contact repl.it to check that with them.

@elalaouifaris Did you have any luck with running JuMP on repl.it? I am facing the same precompile error issue.

Unfortunately there is no progress on this.  
I filed a [issue](https://repl.it/bugs/p/julia-jump-package-fails-to-compile)on the Repl.it site, but it’s still under review.

I’m traveling the next 3 days but will follow up on this mid next week.
