SymPy does not precompile in v1.2?

General Usage
1

I am trying to use SymPy to do some symbolic manipulation in Julia. A simple code like

using SymPy

@vars x

f(x) = e^x

results in an error when precompiling:

When doing

Pkg.build("fvheQ")

as provided in the error message I get the message that fvheQ does not exist as package.

Could somebody help? Thanks!

I also find that using SymPy by itself fails in the REPL using Julia 1.2, but the error is due to the SpecialFunctions module, not SymPy.

Doing Pkg.build("SpecialFunctions") made the error go away for me. I suspect that there was/is a problem in its build script that broke upgrades.

That did the job. Thanks Steven! :+1:
