Julia 1.4.2 fails to include Plots package

Hi,
I am trying to do simple plots in julia. I wrote,
using Pkg
Pkg.add(“Plots”)
and it failed. It displayed some lenghty text about FFMEG artifacts in red colour.
How do I fix it?

Its okay in linux but fails in windows 7. I will get error message shortly.

The legend says that a man once managed to include Plots on the first try. I am yet to meet that man…

Similar error happened when I typed
“”“using Pkg
Pkg.add(“Plots”)”“”
to install Plots packages.
Below are error codes:
“”" 使用“2”个参数调用“DownloadFile”时发生异常:“在 WebClient 请求期间发生异常。”

ERROR: Unable to automatically install ‘FFMPEG’ from ‘C:\Users\41832.julia\packages\FFMPEG_jll\tCUYA\Artifacts.toml’“”"
I have searched solution to this problem on StackOverFlow and found nothing.
