Issues (different) on both PY2.7 and PY3.5

[Bob2345de]

Install seems successful but error as follows installed on Python2.7.9:
@raspberrypi:~ export YEELIGHTBT_MAC=F8:24:41:C0:36:AF
@raspberrypi:~ yeelightbt

Traceback (most recent call last):

Thank you!!

Found the issue. There were some changes made to "construct" as described here: construct/construct#642

Overwriting the constructs directory with the contents from an older version 2.9.25 (available here https://github.com/construct/construct/releases/tag/v2.9.25 ) solved the issue on Python3.5, it now works!

I suspect that some changes will need to be made to yeelightbt to keep it compatible going forward.

Thanks

The construct's API is currently unstable, but this issue will probably be fixed by PR #16. Btw, you should use pip to install the packages instead of manually copying files over, so pip install construct==2.9.25 should work :-)

python-yeelightbt requires Python '>=3.4' but the running Python is 2.7.13 not work install

[arekbulski]

Construct has achieved what you would call a "stable API". Well, almost stable: the issue described in the PR (EmbeddedSwitch) remains unresolved. But otherwise, its stable. :)

👍 I will close this issue, this project does not support python 2, and the symmetricmapping problem is tracked in #18.
