I have a Package “Foo” I have developed in .julia\dev.

I just updated to Julia version 1.6.3 in Win10.

When I updated to 1.6.3 I updated the package “] update Foo” and then in the REPL when I type ‘using Foo’ the commands exported from Foo are available.

I then load Pluto, and Pluto complains with the following message: " The package _“Foo”_ could not be found in the registry.

_Did you make a typo?_"

I go to “….julia\registries\General\Registry.toml” and indeed I cannot find “Foo” anywhere in the file.

Any ideas or directions for me?

No, this is because Pluto.jl is trying to be reproducible and so it **does not respect your `dev`’d packages**.

If you want package managment in Pluto to work the way it works in your repl, you need to do

```julia
begin
    using Pkg
    Pkg.activate(".")
end

```

in your notebook which will disable Pluto’s custom package managment scheme.
