Kubuntu 18.04.4 LTS  
Julia 1.4.2 installed in /usr/local/julia-1.4.2  
bashrc modified: PATH=/usr/local/julia-1.4.2/bin:$PATH  
$HOME/.julia contains: artifacts, compiled, conda, environments, logs, packages, prefs, registries  
“Packages” includes DifferentialEquations, PGFPlotsX, PLots, and many others packages;

Hello dear all,

Since yesterday after some problems in my session, I am trying to resolve a very annoying problem. Each time I want to run a program, Atom (REPL) tells me:

```julia
prerecompiling Atom (sometimes)

```

```julia
precompiling DifferentialEquations

```

and

```julia
The following package names could not be resolved:
 * PGFPLotsX (not found in project, manifest or registry)

```

Sometimes it works sometimes it doesn’t.

I had a look on [this discussion](https://discourse.julialang.org/t/frequent-and-annoying-precompilation-when-using-several-pkg-environments/21963) but I don’t find the correct way to resolve my problem.

Any idea?

I must had that if I do:

```julia
julia > using Plots (or PGFPlotsX)

```

There is no problem

If I do:

```julia
julia > using DifferentialEquations

```

I get:

```julia
Julia has exited.
Press Enter to start a new session.

```

in such cases i tend to clean (rm) my `~/.julia` completely and recompile everything.

Thank you MatFi for your replys. 🙂

Earlier I applied your solution but there was still something unstable.  
Finally I uninstalled/resinstalled Atom since it called an old Julia version (1.0).After a new install, Atom required to “readjust” some links (however without telling more details). Just click “yes” and … everything came back OK.
