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?

How long was the message, approximately?

Just kidding :wink: Can you please copy paste the error message?

Btw. if you want to get help quickly and efficiently, check out this short introduction how to make it easier to help you: https://discourse.julialang.org/t/psa-make-it-easier-to-help-you

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

Version 1.4.2 (2020-05-23)

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。”

I have searched solution to this problem on StackOverFlow and found nothing.

I was trying to install Plots package with Julia REPL but failed.
