Error during precompiling DataFrames.jl: UndefVarError: ComposedFunction not defined

Question

I'm using Julia 1.5.3 and last versions of module DataFrames.jl (v0.22.0) and Compat.jl (v3.23.0). I've added DataFrames into my project enviroment as usual:

]add DataFrames

Last time I've used DataFrames package in July 2020. Now when i'm trying to use (call using DataFrames) the package I have an error:

[ Info: Precompiling DataFrames [a93c6f00-e57d-5684-b7b6-d8193f3e46c0]

But tests Pkg.test("DataFrames") have passed corretly without an errors!

I think I have some troubles with the Compat - package. When I'm trying to export ComposedFunction separetly:

using Compat: ComposedFunction

I also have an error:

UndefVarError: ComposedFunction not defined
in include_string at base\loading.jl:1088

I've tried several things:

• remove the packages and install again;
• ]up
• Pkg.resolve
• update Julia from 1.5.2 to 1.5.3
• restart computer, of course
• delete all folders besides "dev" and "environment" from .julia directory

but the errors still exist.

Thanks for your help.

I've re-run Atom again in administrator mode and all errors disappeared. Now everything works without admin mode also. Magic.
