I have been watching a lot of videos lately around home automation lately and found that Home Assistant (
HASS) seems to be the most popular choice when it comes to consolidating all of your IoT enabled devices. Hass offers a clean, powerful and easy to use interface that displays all of your nodes / sensory data through a consistent, mobile friendly viewport with support for over
800 unique inputs into the system.
I was sold on this pretty much straight away and wanted to get up and running as soon as possible. I downloaded and installed the latest stable release of Python (ensuring to add the python executable to my system
PATH) and ran the install command:
pip3 install homeassistant
Unfortunately I was greeted with the following error:
2017-09-04 17:40:29 ERROR (SyncWorker_6) [homeassistant.util.package] Unable to install package netdisco==1.1.0: Command "c:\users\administrator\appdata\local\programs\python\python36-32\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\ADMINI~1\\AppData\\Local\\Temp\\2\\pip-build-d9xyxziz\\netifaces\\setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record C:\Users\ADMINI~1\AppData\Local\Temp\2\pip-3vu4z519-record\install-record.txt --single-version-externally-managed --compile --user --prefix=" failed with error code 1 in C:\Users\ADMINI~1\AppData\Local\Temp\2\pip-build-d9xyxziz\netifaces\ 2017-09-04 17:40:29 ERROR (MainThread) [homeassistant.setup] Not initializing discovery because could not install dependency netdisco==1.1.0 2017-09-04 17:40:29 ERROR (MainThread) [homeassistant.setup] Setup failed for discovery: Could not install all requirements. 2017-09-04 17:40:30 ERROR (MainThread) [homeassistant.core] Error doing job: Exception in callback _ProactorReadPipeTransport._loop_reading(<_OverlappedF...op_reading()]>) Traceback (most recent call last): File "c:\users\administrator\appdata\local\programs\python\python36-32\lib\asyncio\events.py", line 127, in _run self._callback(*self._args) File "c:\users\administrator\appdata\local\programs\python\python36-32\lib\asyncio\proactor_events.py", line 190, in _loop_reading data = fut.result() # deliver data later in "finally" clause File "c:\users\administrator\appdata\local\programs\python\python36-32\lib\asyncio\futures.py", line 239, in result raise InvalidStateError('Result is not ready.') asyncio.base_futures.InvalidStateError: Result is not ready.
Basically the error was saying that the installation of HASS was failing due to a missing dependency (
netifaces), I attempted to install this using an elevated command prompt window and the following command:
pip3 install netifaces
This too failed, and when looking at the output it became apparent that I was missing
Microsoft Visual C++ 14.0:
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual
This is simple enough to fix, and after a quick search on Google I found the relevant build of
Microsoft Visual C++ 14.0 for my system here. I downloaded them and ran the installer:
Once completed I re-opened a new command prompt window and attempted to install
pip3 install netifaces
Great success, the installation went through without any hitches:
I re-ran the installer for HASS and it completed successfully, now I just need to start plugging in all my devices :)
Hopefully this will save you some time in the future when setting everything up on windows.
