Dear all,  
I am with serious problem. I cannot to build the package PyCall to use the Package SymPy.  
I am with Julia 1.5, recently installed.  
I have run:

Pkg.add(“PyCall”)  
import Pkg; Pkg.add(“Conda”)  
Pkg.build(“PyCall”)  
in this last line, Julia spend hours installing and nothing happens.  
Anyone can help me please?
