I am an amateur user, just using latex for the past one week. When I ran a sample presentation (from the book "Practical Latex" by George Gratzer), I get this error message that a particular file called
pgfcore.sty is missing.
I have installed the
beamer package from the MiKTeX console.
Should I find the missing file and manually install it? If yes, how to do that? I'm stuck at this point and I will be very grateful if you could help me with this? I am using MiKTeX version 2.9 with Windows10 OS.
