What am I missing here? I already have CSV installed and it is working perfectly.

Answer 1

In Windows 10, I followed these steps :
Open C:\Users\user\.julia\registries
Delete everything within this folder ( Don't worry they will be autocreated )
Open Julia terminal. At this point you should be at julia> prompt
Enter ] and press enter. At this point you should be at pkg prompt
add CSV
To go back to julia prompt press Ctrl + C.
This will resolve the issue. Please note deleting registry folder contents means all previous packages will be deleted. You need to add all packages one by one. However it is worthy.

Such problems are usually caused by cluttering the current environment, or having old versions of several packages.
If you're using base environment, create a new one and install packages there by by
using Pkg
pkg"activate ." # activates new environment
pkg"add DataFrames CSV Plots LaTeXStrings" # adds all packages using handy macro
using DataFrames, CSV, Plots, LaTeXStrings
if it does not help, delete Manifest.toml and upgrade all your packages.
If it's successful, following versions should be installed
using Pkg
pkg"st"
[336ed68f] CSV v0.7.7
[a93c6f00] DataFrames v0.21.6
[b964fa9f] LaTeXStrings v1.1.0
[91a5bcdd] Plots v1.5.8
[44cfe95a] Pkg
Also, if you already have clutterd the base environment, clean it up.
You can see it by
using Pkg
pkg"activate; st"
which prints list of packages installed in the base environment.
