Modia fails to precompile in v1.0

[tpdsantos]

Even last week I was able to use Modia with no complications. Today I was trying to continue my work but now I can't even open Modia. This is what appears to me:

julia> using Modia

Type "?Modia" for help.

Does everyone know what's going on?

Thanks in advance

I am sorry: The reason is that Unitful is used in Modia and there was recently a new release in Unitful (0.14.0) that is not compatible how Unitful is used in the last Modia release (Modia uses a workaround to fix an issue with Unitful and this workaround does not longer work in Unitful 0.14.0). This issue has been already fixed on the master. So, the short-term fix is to define that the master version of Modia should be used:

julia
]
remove Modia
add Modia#master

We will try to soon release a new Modia version (but want to first fix some other issues too).

Oh Ok, no problem! Thanks for the tip :)
