Grisu not defined - Julia - plot

Question

I have just started to use Julia a few days back.
While trying to plot, I am getting the following error:
using Plots
x = 1:10; y = rand(10); # These are the plotting data
plot(x, y)
ERROR:
UndefVarError: Grisu not defined

Googles it for a few hours. Saw some similar queries but couldn't find a satisfactory solution. Have got both Plot and Grisu packages installed.

Answer 1

Following up on some of the conversation in the comments, the correct steps to resolve this would be:
# Type "]" to enter the package manager and then
remove plots
add plots
which should resolve this issue.

Answer 2

apparently Grisu was removed from Julia base after Julia 1.6. However, some older packages might still refer to it, so you need to add the now stand-alone Grisu package if you need to use older package versions.
https://juliahub.com/ui/Packages/Grisu/T2ZVU
Pkg.add("Grisu")
if isdefined(Base, :Grisu)
import Base.Grisu
else
import Grisu
end
