Install pyephem

[Kevin Davis]

I'm having some problems getting pyephem apparently.  I'm still seeing the "Install pyephem for detailed celestial timings." text.

I did a sudo pip install pyephem and restarted weewx.  I don't see a lot of documentation on this install, so I'm not sure where to start troubleshooting.

This is a brand new install weewx that I'm building for an in-law for Christmas.  Running in simulator mode currently.

Thanks for any help.

Oh, maybe I needed to do a pip3 install instead?

I recently built a new system. I had trouble getting pyephem installed also. I think I ended up doing a apt install pyephm to get it to work. I unfortunately don't take good notes while troubleshooting.

It looks like you are running python3.  Try:

apt install python3-ephem

http://www.weewx.com/docs/ has the installation instructions.

Pick setup.py or an os-specific package from the links.  Each page has the right instructions for your os+version combination.

If you run the packaged installer, the packages do the right thing almost always.   If you run the setup.py variant you have to install the prerequisites properly to match your os+version's needs.

Also, for future folks asking these kinds of questions, please always tell us your os+version and whether you're using the pre-packaged weewx or whether you installed via setup.py so we can try to help without a lot of back+forth.

(only reason I mention it here is for future folks finding this thread via a seach, as this is a very much Frequently asked question)

This was the only reference to Pyephem that I found.  Sorry if I missed it elsewhere.
