I seem to be stuck in a cycle, trying to install the latest versions of `DataFrames` and `CSV`.

Can anyone suggest a way out, or how to further diagnose the issue?

```julia
(v1.4) pkg> add DataFrames@0.21

   Updating `D:\...\environments\v1.4\Project.toml`
  [336ed68f] ↓ CSV v0.5.26 ⇒ v0.3.1

When these things happen and I really want to have the latest version of each package, I open different environments for each. Not an ideal solution, but it works. So, in my case, ODBC.jl and DataFrames 0.21 are not compatible right now, so I have a `Julia_Projects/ODBC` and a `Julia_Projects/DataFrames` folders, I go to the first one, `] activate .` and `] add ODBC`. I get whatever I need from the database in this case and my DataFrames version on this projects is 0.20.2 I can the go to the DataFrames folder and `] activate .` this new environment and `] add DataFrames`. In this new clean environment, DataFrames will be v0.21.

So, again, not ideal and packages will catch up to DataFrames with time, but for now it’s a working solution.

OK thanks.  
I can work around for now.  
So I guess you’re saying it’s known that latest versions of `DataFrames` and `CSV` are incompatible, and not something peculiar to my setup?

Yes, packages have `[compat]` boundaries that developers establish to guarantee compatible versions and those create those problems. You’ll find cases like frequently, most things get resolved fairly quickly, but sometimes it can take a while. At the same time, I’m getting into the habit of working with environments, creating folders and activating them for almost everything I do in Julia. It’s a little more work, but I like to keep up to date with certain packages, like `DataFrames`.

I know there are some other possible solution removing the `[compat]` boundaries from the package, but I’ve never done that in the past.

CSV.jl is at 0.6.2 currently and compatible with DataFrames 0.21: [CSV.jl/Project.toml at main · JuliaData/CSV.jl · GitHub](https://github.com/JuliaData/CSV.jl/blob/master/Project.toml)

Your problem above is that you’re trying to force the latest DataFrames (0.21) to work with an outdated CSV version (0.5)

Thanks!

I was on the wrong track because `CSV` was held back to `v0.5.26`.  
Trying to `add CSV@v0.6` gave some extra clues.  
Seems `XKCD` was the culprit, indirectly holding back `CSV`.  
I removed `XKCD` and all good now.

```julia
(v1.4) pkg> add CSV@0.6
