psutil makes extensive use of C extension modules, meaning a C compiler is required. For these 3 platforms though, pre-compiled cPython wheels are provided on each psutil release, so all you have to do is this:
pip3 install psutil
If wheels are not available and you whish to install from sources, keep reading.
Ubuntu / Debian:
sudo apt-get install gcc python3-dev pip3 install --user psutil --no-binary :all:
RedHat / CentOS:
sudo yum install gcc python3-devel pip3 install --user psutil --no-binary :all:
In order to compile psutil on Windows you'll need Visual Studio. Here's a couple of guides describing how to do it: 1 and 2. And then:
pip3 install --user psutil --no-binary :all:
Note that MinGW compiler is not supported.
pkg install python3 gcc python3 -m pip3 install psutil
export PKG_PATH=http://ftp.eu.openbsd.org/pub/OpenBSD/`uname -r`/packages/`uname -m`/ pkg_add -v python gcc python3 -m pip install psutil
export PKG_PATH="ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/`uname -m`/`uname -r`/All" pkg_add -v pkgin pkgin install python3 gcc python3 -m pip install psutil
If cc compiler is not installed create a symlink to gcc:
sudo ln -s /usr/bin/gcc /usr/local/bin/cc
Install:
pkg install gcc python3 -m pip install psutil
python3 -m psutil.tests

Pip is shipped by default with Python 2.7.9+ and 3.4+. If you don't have it you can install with wget:
wget https://bootstrap.pypa.io/get-pip.py -O - | python3
...ow with curl:
python3 < <(curl -s https://bootstrap.pypa.io/get-pip.py)
On Windows, download pip, open cmd.exe and install it:
C:\Python27\python.exe get-pip.py
If you bump into permission errors you have two options. Install psutil for your user only:
pip3 install --user psutil
...or prepend sudo and install it at system level:
sudo pip3 install psutil
