Error in installing flux?

I have installed v1.0.5

Why are you using Julia v1.0? The current release is 1.5.3, and there’s already a release candidate for 1.6 so your version is quite outdated.

Also with these kinds of compatibility errors in general you should look to work in environments for your projects, rather than trying to dump all packages into the default environment.

thanks for suggestion… I appreciate that
