Answer 1

I don't know if this is the same problem (I am working on a vanilla Ubuntu 16.04), but I was getting a similar frustrating message around psutil . The problem seemed to be that it was installed in my Python 2.7 version, and pip was only looking at that version, seemingly ignoring the fact that my current virtual environment was Python 3.5.

I noticed pip3 did nothing, so I installed pip3 with apt-get install python3-pip . Then I could could successfully use pip3 install psutil to install into the correct Python3.5 and my virtual directory.

What I am puzzled by is how I got so far without hitting this earlier. I have installed lots of things over the last few months with pip and they seemingly went into both versions (side-by-side Python2.7 and Python3.5 environments for running TensorFlow). Why is it different for psutil ?

But it works now.

Perhaps these steps might fix your problem.

Change the Python3 default version in Ubuntu

From the comment:

sudo update-alternatives --config python

Will show you an error:

update-alternatives: error: no alternatives for python3 

You need to update your update-alternatives , then you will be able to set your default python version.

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.6 2

Then run :

sudo update-alternatives --config python

Set python3.6 as default.

Or use the following command to set python3.6 as default:

sudo update-alternatives  --set python /usr/bin/python3.6
