ModuleNotFoundError: No module named 'jplephem.pck'

[Shawn Honomichl]

Did an update and attempted fresh install on another computer (both macs) of the mss and started getting the following python error that prevented the MSS from running:

from jplephem.pck import DAF, PCK
ModuleNotFoundError: No module named 'jplephem.pck'

Was able to get around the issue by force reinstalling jplephem…Likely an issue with the skyfield package.?.

The recipe has set a rule
skyfield >=1.12

‌

I see on conda-forge now 1.16. released 9days ago, https://anaconda.org/conda-forge/skyfield/files

which version is on your system?

this looks like similiar to:

https://github.com/conda-forge/skyfield-feedstock/issues/24

[Shawn Honomichl]

I am also using version 1.16.

[Reimar Bauer]

I looked up the recent jplehem builds https://github.com/conda-forge/jplephem-feedstock/pulls doctests are failling, the pypi version is 2.12 but since 2.10 the conda build system finds errors.

[Shawn Honomichl]

I was able to resolve the issue by force reinstalling jplephyem.

[Reimar Bauer]

if I try to install manually conda create -n pbenv jplephem

I can reproduce the problem

‌

from jplephem.pck import DAF, PCK

Traceback (most recent call last):File "<stdin>", line 1, in <module>ModuleNotFoundError: No module named 'jplephem.pck

‌

but pip install jplephem --upgrade solves it

‌

‌

For the next mss release we have to get the package on conda-forge fixed first

[Reimar Bauer]

added an issue to

https://github.com/conda-forge/jplephem-feedstock/issues/17

[Reimar Bauer]

we can now use jplephem>=2.12

[Reimar Bauer]

We just created a new build of skyfield and I verified this in a new env
https://anaconda.org/conda-forge/skyfield/files
