    **Error:  Cannot satisfy the dependency on npeg 0.27.0 and npeg 1.2.2**

Sorry for the late reply. I pushed 2626.4.1 to open the npeg version range; please give that a try.

[michele-comitini]

If one has not previously installed npeg@0.27.0 before it fails too. because balls->ups depends on npeg@<2.0.0 resulting in npeg@1.2.2 being installed.

OP reporting back. I updated my nimble file to requires "atoz == 2626.4.1". That still failed so I added requires "npeg == 0.27.0" per comment from @michele-comitini I suspected the npeg 1.2.2 is already cached somewhere so I also did a nimble uninstall -i npeg And... I got past the install issue, thank you!!

There is a new problem now but I don't know if I'm just doing something wrong, I'll open a new Issue depending on how that turns out: \.nimble\pkgs2\atoz-2626.4.1-ff0e0daf22a489a82c2804e53843526e3cf0be41\atoz\s3_20060301.nim(248, 11) Error: the special identifier '_' is ignored in declarations and cannot be used
