I installed Julia1.4 and was adding various needed packages, but CMake failed – it could not find wget/curl.

In trying to fix this, I seemed to have broken things badly: following various rm/add/upgrade/etc, Pkg.build(“CMake”) is clearly doing nothing, and other packages that depend on it say that cmake is not installed. I did manually remove a downloads/ directory inside CMake (that was referred to in one of the error messages), that probably did not help.

Anyway, **I would like to remove all 1.4 packages and start over, but without removing any packages for older julia versions.** How can I do this?  
(There is a project that uses a prevous julia and works and needs to keep working…)

See discussion here:

> Thanks, I’m excited to test drive Julia v1.4! The first thing I did in Julia v1.4 was add the package [MLJ.jl](https://github.com/alan-turing-institute/MLJ.jl/releases). Julia installed MLJ v0.2.3 instead of the latest version MLJ v0.10.1. Is there some kind of testing that can be done before a new version of Julia is released to check that, say, the top 20 Julia packages (by github stars) work? And the maintainers can be notified pre-release if there is an issue? Update: I ran rm -rf ~/.julia , opened Julia & Pkg.add("MLJ") now installed the latest…

thanks. Catalina is not the problem however - I am on Mojave 10.14.

I did not upgrade yet because a different app that I use is 32bit only.

I wasn’t referring to Catalina, you have to read the entire post.  
If you run the following in `utilities` on a mac:  
`rm -rf ~/.julia`  
it will automatically remove all packages

I was hoping to avoid that, but yes, it was a good solution in the end
