python - How to make nosetests use python3

Question

I try to use nosetests
? nosetests '/pathTo/test'

but it uses python 2.7 for my tests:

sys.version_info(major=2, minor=7, micro=5, releaselevel='final', serial=0)

So some of them fails, because they were written in python 3.3.

I work it around and installed virtual environment:

pyvenv-3.3 py3env

Activated it:

source ~/py3env/bin/activate

Check python virsion in virtual environment:

? python --version                                                                                 ?
Python 3.3.3
(py3env)

Ok. But nosetest still uses python2.7 even in virtual environment:

sys.version_info(major=2, minor=7, micro=5, releaselevel='final', serial=0)

So my tests fails. How to make nose use python3?

Answer 1

In Python 3.4 and higher versions: in order to make nose use python3 just run ...

python3 -m "nose"

... in the target directory with the tests.

The environment setups are not required.
