Unsatisfiable requirements detected for package Compat during Pkg.add("DataFrameMacros") - package

Question

I am adding package "DataFrameMacros". This results in error:

I have read here Julia "Unsatisfiable requirements detected for package" error when installing multiple packages on how to read the status conflict error. It seems that Compat requires a newer DataFrame version than DataFrameMacros I am trying to install.
So Campat and DataFrameMacros seem to be incompatible.
However, I don't know where Compat came into play as I only try to install DataFrameMacros.
The packages I actually need for the code I am running are:
using PyPlot
using CSV
using DataFrames
using StatsBase
using PyCall
using Cairo
using Fontconfig
using Distributions
using DataFrameMacros, Chain
using Optim
Does anyone have a suggestion of how I can solve the error and install DataFrameMacros?

Answer 1

The problem is ultimately due to Bio.jl - note that Bio.jl is deprecated, and the Github page archived. There's a blog post that unambiguously says:
It is not longer recommended that you use Bio.jl.
and gives the list of packages which have the functionality Bio.jl used to have. You can choose which of those to install based on what features of it you needed. Or if your list of "packages I actually need" is complete, it seems you don't need Bio.jl at all. In that case, you can just rm Bio and add DataFrameMacros instead.
This sort of issue is likely to arise again if you install everything in the default Julia environment #v1.7. I'd recommend that you instead do ] activate /your/project/folder (in the Julia REPL) to create a new environment there, and add the just packages you need for this project there. That will keep your projects from stepping on each other's toes and make conflicts like this less likely.
