Hello !  
For a course I am trying to use julia for the first time. I tries to use the package Pyplot (I had it with python).  
But, when I run the command: Pkg.add(“Pyplot”)  
I get this error I didn’t find about on internet:

[1] pkgerror(::String) at D:\buildbot\worker\package\_win64\build\usr\share\julia\stdlib\v1.4\Pkg\src\Types.jl:53

What should I do to install this package ?

Thanks a lot !
