guix import error

[Zelphir Kaltstahl]

Hi Guix users!

Today I tried to import another package from PyPI:

~~~~
$ guix import pypi 'jupyterlab@2.1.5' --recursive
following redirection to `https://pypi.org/pypi/jupyterlab@2.1.5/json/'...
Backtrace:
           4 (primitive-load "/home/user/.config/guix/current/bi…")
In guix/ui.scm:

guix/import/utils.scm:427:36: In procedure recursive-import:
Wrong number of values returned to continuation (expected 2)

But when I leave away the version, it works:

~~~~
$ guix import pypi 'jupyterlab' --recursive

So I checked in the manual and there is says:

> A specific package version may optionally be specified by following
the package name by an at-sign and a version number as in the following
example:

> guix import hackage mtl@2.1.3.1

But that is in the "hackage" import section. Is the same not available
for PyPI?

When I check with:

~~~~
$ guix import pypi 'jupyterlab@2.2.8' --recursive
following redirection to `https://pypi.org/pypi/jupyterlab@2.2.8/json/'...
Backtrace:
           4 (primitive-load "/home/user/.config/guix/current/bi…")

guix/import/utils.scm:427:36: In procedure recursive-import:

~~~~

It also errors, although 2.2.8 is the version shown on PyPI currently.

Do the various importers work differently?
