micromamba hash mismatch

[boriskaus]

I'm using PythonCall as part of my package, and am consistently getting the follow bug in the CI (used to work fine).

See the full CI here.

I'm not sure whether the problem is here or down the line in the MicroMamba.jl package, but can imagine that other users may encounter the same. Help is appreciated.

I have the same issue

[boriskaus]

It seems to me that MicroMamba v0.1.10 is broken.

A workaround is to explicitly install MicroMamba 0.1.9 before installing PythonCall:

julia> ]
pkg> add MicroMamba@0.1.9
pkg> add PythonCall

obviously a better solution would be to fix 0.1.10

Fixed now thanks.
