Error in using DifferentialEquations

General Usage

I just installed Julia and was testing out some packages. I installed DifferentialEquations but I get the following output when I try using it:

I tried reinstalling various dependancies but none of it worked. I’m using Ubuntu 18.04.4.

What is your Julia version and DataFrames version? Seems like you are using a DataFrames version that requires Julia 1.1 or above… (although the package manager shouldve caught this). Can you run versioninfo() and ] st in the REPL?

Julia Version 1.0.4 and the ] st returns:

Status ~/.julia/environments/v1.0/Project.toml
[a93c6f00] DataFrames v0.20.2
[0c46a032] DifferentialEquations v6.10.1
[61744808] DynamicalSystems v1.4.0
[7073ff75] IJulia v1.21.1
[1dea7af3] OrdinaryDiffEq v5.29.0
[65888b18] ParameterizedFunctions v4.2.1
[91a5bcdd] Plots v0.29.7

As a built-in package, shouldn’t DataFrames be compatible by default?

It’s due to using v1.0 and last night’s release. I’ll put out a bugfix version (and then make the versions on 1.0 fixed…)

Thanks for such a fast reply, I seem to have a similar issue, though it’s little harder to check, since we only need differential equations during testing. The error message however refers to the same line. Do you have an idea, how this can be solved? The log of our test is

Is I can help with any further information, let me know.

DiffEqBase.jl v6.23 add Compat for eachcol, but it seems something happened there. So I’m going to figure out what’s up with Compat and handle that…

Thanks, it’s resolved, its now loading 6.20 and that works fine with Julia 1.0

Perfect. Good to hear. I am sad Compat isn’t working here, but anyways, we need to drop 1.0 support from the latest releases because there’s starting to be a lot of stuff that v1.0 cannot do. Our v1.0 release should just be a good stable release that doesn’t change.

Same issue when installing only DifferentialEquations.
Solved by installing DataFrames before.
