avandeputte Posted October 29, 2019 Share Posted October 29, 2019 Just got my polisy today. I tried installing the LutronCaseta module, it install fine. Trying to run it, the log shows this error: 2019-10-28 16:50:10,734 [MainThread] [INFO ] Received Config from STDIN. 2019-10-28 16:50:10,736 [MainThread] [INFO ] UDI Polyglot v2 Interface 2.0.31 Starting... 2019-10-28 16:50:11,564 [MainThread] [ERROR] Traceback (most recent call last): 2019-10-28 16:50:11,564 [MainThread] [ERROR] File "./lutroncaseta-poly.py", line 10, in <module> 2019-10-28 16:50:11,565 [MainThread] [ERROR] from lutron_caseta_nodes.LutronCasetaController import LutronCasetaController 2019-10-28 16:50:11,566 [MainThread] [ERROR] File "/var/polyglot/nodeservers/LutronCaseta/lutron_caseta_nodes/LutronCasetaController.py", line 9, in <module> 2019-10-28 16:50:11,567 [MainThread] [ERROR] from cryptography import x509 2019-10-28 16:50:11,568 [MainThread] [ERROR] ModuleNotFoundError 2019-10-28 16:50:11,568 [MainThread] [ERROR] : 2019-10-28 16:50:11,568 [MainThread] [ERROR] No module named 'cryptography' OK, so next I logged in the polisy, navigated to the nodeserver and ran install.sh It fails on installing cryptography, perhaps because there is no compiler installed?

This appears to suggest that you don't have lifxlan installed. I haven't tried to migrate my LiFX nodeserver over yet, but this is what I did to install lifxlan: [admin@polisy ~]$ sudo pip3 install lifxlan Password: Collecting lifxlan Downloading https://files.pythonhosted.org/packages/77/ce/7e0b99a28555e89901a8a7da76d790a6909adc3832d3f0c9dfaf28200827/lifxlan-1.2.5.tar.gz Collecting bitstring (from lifxlan) Downloading https://files.pythonhosted.org/packages/c7/b9/ce7458b35633968eae3477a201a00f6c8e01cab0ccb200ea5099d41dd977/bitstring-3.1.6-py3-none-any.whl Requirement already satisfied: netifaces in /usr/local/lib/python3.7/site-packages (from lifxlan) (0.10.9) Installing collected packages: bitstring, lifxlan Running setup.py install for lifxlan ... done Successfully installed bitstring-3.1.6 lifxlan-1.2.5 Link to comment Share on other sites More sharing options...

Bumbershoot Posted October 29, 2019 Share Posted October 29, 2019 FWIW, I've got the LiFX nodeserver running on Polisy.

Michel Kohanim Posted October 29, 2019 Share Posted October 29, 2019 @MWareman and @Bumbershoot, thanks so very much. @avandeputte, no compilers are installed because node servers should not depend on compilers. Almost all these libraries are available and we missed them during the rollout. In short, completely and utterly inexcusable rollout even for geeks. We are working getting everything in order. Thanks again for all your input. With kind regards, Michel Link to comment Share on other sites More sharing options...
