I have read some old similar questions, but could not find a suitable solution. When I enter using DifferentialEquations this is what I get. Someone can tell me what it is going on, please? Thank you!

```julia

My first guess would be there are incompatible version requirements of different packages (assuming it is not a simple installation problem). When I ask for

```julia
Pkg.update()

```

I currently get an answer like

```julia
  57 dependencies successfully precompiled in 210 seconds (379 already precompiled, 3 skipped during auto due to previous errors)
  6 dependencies errored. To see a full report either run `import Pkg; Pkg.precompile()` or load the packages

```

I don’t know if there is a less intrusive way than `update()` to get this status information, though.

Is that Julia v1.6? Can you share the whole error?
