I’ve been setting up Julia to learn via QuantEcon and one of the packages they recommend me to install is symbolics.jl. However, I’ve been getting the following error:

```julia

I have tried removing DataStructures but it keeps coming up with the same error despite having removed that package already. Is there any way to work around these issues or am I missing something.

I am on a 2015 MacBook Pro 13 with 8GB RAM if this is a hardware issue.

This is not a hardware issue - you just have all you packages installed in the global environment, leading to version conflicts.

Work in a project specific environment (`] activate path/to/my/analysis`) and add only the packages you need for the analysis you’re currently doing to minimise this issue.

Also as a general point you are reading the output wrong - your problem is not having `DataStructures` installed, the problem is that different packages in your environment need different versions of `DataStructures`. If I’m reading correctly `JuliaDB` only works with `StatsBase` up to 0.33.13, which only works with `DataStructures` up to 0.17, while `Symbolics` needs `DataStructures` 0.18

Ok that makes sense. I’ll try that now!
