Hi. You need to run
sudo pip install -U future
in a terminal to add the library in question. It's added already for our Raspbian for Robots so I'm assuming you're running your own OS.
Hi! I am running the Raspbian for Robots downloaded from here: https://drive.google.com/file/d/0B0WChwP4CnLBV2R6VE8yeFF2ZFU/view?usp=sharing as per instructions reported here: https://www.dexterindustries.com/howto/install-raspbian-for-robots-image-on-an-sd-card/ I have just re-imaged the micro SD with it, it is a fresh install. Here the output of uname -a
Linux dex 4.4.32-v7+ #924 SMP Tue Nov 15 18:11:28 GMT 2016 armv7l GNU/Linux
Should I use a different image instead?
You're doing every thing right. The issue is that this is a recent change. Our apologies.
Did you pull down the repo directly from Github? In short, you seem to be out of sync. If you go through DI Update, you would be getting the latest BrickPi code and the library import that is now required.
Or you can just enter
sudo pip install -U future
in a command prompt to get the missing library.
And thank you for bringing this to our attention. There's now a PR that will take care of this for others . https://github.com/DexterInd/BrickPi_Python/pull/79
I downloaded the repo from github as a zip file. sudo pip install -U future resolved the issue. Thanks!
Great!!!
Just to be safe, you also need to run
python setup.py install
if you haven't already done so.
In the output of pip I see BrickPy is already installed. Do I need to run python setup.py install nevertheless?
} pip list | grep BrickPi
BrickPi (0.0.0)
Since your base is Raspbian for Robots, and it's the latest version, you're most likely set and don't need to run it. Apologies again for this hiccup you faced.
