Error running scripts/update while Cleaning up...

[Nolan]

After running scripts/update I get an error during cleanup.  I tried to uninstall PyChromecast0.6.8.2 myself but couldn't figure it out.  Any ideas?  

Love the new update, great work everyone.

Installing collected packages: pychromecast, psutil, python-forecastio, PyMata, pyserial, responses, cookies, mock, pbr
  Found existing installation: PyChromecast 0.6.8.2

Hi Nolan. It looks like you are getting permissions errors because pychromecast is installed in your systems built in Python repository. Try prepenfing the sudo command to your pip call. Like this:

sudo pip uninstall pychromecast

Home assistant has moved to using virtual environments to manage all the Python dependencies. It is a lot cleaner. Check out the install instructions in the Readme for details. A word of warning though, if you are specifically using Ubuntu 14.04, you'll need to do some extra work. I can help you through that of you need.

Thanks for the reply, Ryan.  I had actually tried your suggested command before with no luck:

pi@raspberrypi2 ~ $ sudo pip uninstall pychromecast

Cannot uninstall requirement pychromecast, not installed

I had also tried reinstalling home-assistant using the new installation instructions using venv with the same results.  There is no error on initial installation, but I still get the error running scripts/update.

Finally as you can see from my prompt I'm using a raspberry pi running Raspbian.

Thanks,

Nolan

Try this

git clone --recursive https://github.com/balloon/home-assistant.git

python3 -m venv home-assistant

cd home-assistant

source bin/activate

python3 -m homeassistant

I added that source line. This line will force the virtual environment to be activated. Do this with a fresh download, but make sure to backup your config directory. Let me know how it goes.

Thanks,

Also, from my first reply, it should actually be

sudo python3 -m pip uninstall pychromecast

Thank you!  source bin/activate did the trick.

[Ryan Kraus]

Great! 

We may want to add this to the install directions. Also, HA is getting large enough, I think, that it may be time to write a launching script that the user may copy to their /usr/local/bin directory so that they only need to type homeassistant anywhere to launch. This could also be accompanied by an install script. I feel like the install and launching of Home Assistant is what is causing a lot of the questions around here.

Paulus, if you see this, let me know what you think. If you don't see this, I'll track you down.

I think the easiest and most Pythonic way to go would be to publish a package to PyPi that would install an executable. That way we'll have a version number to refer too when people have issues and don't have to depend on git.

Installing an update would be as easy as running pip3 install --upgrade home-assistant (even from the update logic you're working on). We could actually do the update check by fetching a version number from a server that we control so that we can actually see if people are using this shit ;-) Then we'll add unique identifiers for machines and which platforms they use to get even better insight in where to focus our development efforts. Then we will start serving them ads based on the devices in their house and the way they use them and be rich… Oh wait. Skip those last parts :-D
