I solved the problem a different way but I’m getting another problem with mops.

I wonder if it has to do with moc. I have not explicitly installed moc. I don’t know if another command has installed it.

This is the full log: [icrc1/src/ICRC1/lib.mo:16.1-16.40: import error [M0010], package "StableTrieMap" not defined](https://forum.dfinity.org/t/icrc1-src-icrc1-lib-mo-16-1-16-40-import-error-m0010-package-stabletriemap-not-defined/18004)
