Note: pip is the easiest way to install psutil. It is shipped by default with Python 2.7.9+ and 3.4+. If you're using an older Python version install pip first. If you cloned psutil source code you can also install it with make install-pip.

Except for Linux, the commands below assume you're running as root. If you're not and you bump into permission errors you can either:

• prepend sudo, e.g.:

sudo pip install psutil

• install psutil for your user only (not at system level):

pip install --user psutil

Ubuntu / Debian (use python3-dev and python3-pip for python 3):

sudo apt-get install gcc python-dev python-pip
pip install psutil

RedHat (use python3-devel and python3-pip for python 3):

sudo yum install gcc python-devel python-pip
pip install psutil

Install XcodeTools first, then:

pip install psutil

The easiest way to install psutil on Windows is to just use the pre-compiled exe/wheel installers on PYPI via pip:

C:\Python27\python.exe -m pip install psutil

If you want to compile psutil from sources you'll need Visual Studio (Mingw32 is no longer supported):

• Python 2.6, 2.7: VS-2008
• Python 3.3, 3.4: VS-2010
• Python 3.5+: VS-2015

Compiling 64 bit versions of Python 2.6 and 2.7 with VS 2008 requires Windows SDK and .NET Framework 3.5 SP1. Once installed run vcvars64.bat, then you can finally compile (see here). To compile / install psutil from sources on Windows run:

make.bat build
make.bat install

pkg install python gcc
python -m pip install psutil

export PKG_PATH=http://ftp.usa.openbsd.org/pub/OpenBSD/`uname -r`/packages/`arch -s`
pkg_add -v python gcc
python -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 python gcc
python -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
python -m pip install psutil

If you plan on hacking on psutil you may want to take a look at the dev guide.
