Commit 17cfb8e65ea (2023-01-08 06:45 UTC)

After I typed “] add \<package\_name\>” in REPL it will always return an Unsatisfiable requirements Error, for example this is to install “MLUtils”:

To truly diagnose this we will need the output of the following command.

```julia
using Pkg
Pkg.status()
Pkg.status(mode=PKGMODE_MANIFEST)

```

The main issue is that you likely have too many packages in your environment creating a very complicated situation to solve.

The recommended work around is to use a distinct environment for each project. A temporary work around would be to create a temporary environment.

```julia
using Pkg
pkg"activate --temp"
pkg"add MLUtils"

```

To expand on this, it is generally discouraged to use the default environment (in your case, `@v1.8`) for anything other than development- or interface- focused packages. Eg, my default environment has OhMyREPL, MiniLoggers, Revise, BenchmarkTools, and not much else.

Julia’s built-in support for distinct projects with their own package “environments” (a la virtualenv for python) is really great, I’d encourage you to use them. I’d also encourage you to check out [https://modernjuliaworkflows.github.io/](https://modernjuliaworkflows.github.io/)
