Hi Ben, > $ guix import pypi GroopM
[...] > ERROR: In procedure scm-error: > ERROR: no code for module (json) This means that guile-json cannot be found. It is needed to parse the JSON metadata for a given Python module. You initially installed guix with the binary tarball method, did you not? Did it work before "guix pull" or is this the very first time you are trying it? (I do not know why guile-json would not be present when guix was installed via tarball, nor why it would be missing after "guix pull", so I'm hoping for someone else to comment on this.) ~~ Ricardo
