Pi 3 spidev (virtual environment)

[fopetesl]

How can I install spidev for Python 3? Specifically into a virtual environment?

If I "pip install spidev" I get that it's already installed into Python 2.7
I read I cannot uninstall Python 2.7 without probably breaking the Python system(s).

I don't have any spare hair to tear out, it's all gone !!

(search only reveals topics on Pi 2)

Addedum:
I installed wiringpi2 also is installed to Python 2.7, so not accessible by Pi3

What were the exact commands you tried ?

Code: Select all

~$ sudo pip install spidev

~$ sudo apt-get update
~$ sudo apt-get install python-dev python-pip
~$ sudo pip install wiringpi2
~$ sudo python
import wiringpi2
wiringpi2.piBoardRev()

Works bot only in Python 2.7 NOT in Python 3

Hi Dougie

I'm having a similar issue.
However in my case i'm not able to get spidev to be installed into the correct path(That is what i'm guessing).
Below is what I've done.
Hope you could give me some tips:)
Thank you!

(cv) pi@raspberrypi:~ $ sudo pip install spidev
Requirement already satisfied: spidev in /usr/local/lib/python2.7/dist-packages

(cv) pi@raspberrypi:~ $ pip freeze
appdirs==1.4.3
imutils==0.4.3
numpy==1.12.1
packaging==16.8
picamera==1.13
pyparsing==2.2.0
RPi.GPIO==0.6.3
six==1.10.0

i'm trying to run my codes which uses some opencv libraries which gave me the following error hence the question above.

(cv) pi@raspberrypi:~ $ python combined.py --conf conf.json
Traceback (most recent call last):
File "combined.py", line 18, in <module>
import spidev
ImportError: No module named spidev

Thanks again!
