pip3 install didn't put adafruit_ds3231.py in site-packages

[csylvain]

did: pip3 install adafruit-circuitpython-ds3231 and: pip3 install --upgrade adafruit-circuitpython-ds3231

got: adafruit_circuitpython_ds3231-2.1.1.dist-info/ and its contents but: couldn't 'import adafruit_ds3231' because there was no adafruit_ds3231.py in site-packages/

strange. tried to figure it out. then gave up and just grabbed a copy from here and put it in site-packages. import (and the rest) works now.

this isnt too surprising - we havent tested it because on linux you tend to use the built in RTC support

[dhalbert]

pip3 install or pip3 install --user (no sudo) installs in ~/.local/lib/python3.<something>/site-packages. does your sys.path contain that directory?

What OS and OS version are you using?

Might just be a case issue here:

https://github.com/adafruit/Adafruit_CircuitPython_DS3231/blob/master/setup.py#L59

[csylvain]

yes, my sys.path has that directory. i already have bme280, and tsl2561 py modules installed (and tested). Raspbian 9 (kernel 4.14.79+) on a Pi 3B+ kernel has ds3232 rtc driver in /lib/modules/..rtc/ (and some other Dallas P/Ns but no ds3231)

I think it's just case on the name. PR incoming:

follow-up: shouldn't pip3 complain/warn a package was specified but no package file is created in the filesystem? (it's a standard configuration management post-install check)
