Install psutil

Linux, Windows, macOS (wheels)

Pre-compiled wheels are distributed for these platforms, so you won't have to install a C compiler. All you have to do is:

pip install psutil

If wheels are not available for your platform or architecture, or you wish to build & install psutil from sources, keep reading.

Compile psutil from sources

UNIX

On all UNIX systems you can use the install-sysdeps.sh script. This will install the system dependencies necessary to compile psutil from sources. You can invoke this script from the Makefile as:

make install-sysdeps

After system deps are installed, you can compile & install psutil with:

make build
make install

...or this, which will fetch the latest source distribution from PyPI:

pip install --no-binary :all: psutil

Linux

Debian / Ubuntu:

sudo apt-get install gcc python3-dev
pip install --no-binary :all: psutil

RedHat / CentOS:

sudo yum install gcc python3-devel
pip install --no-binary :all: psutil

Alpine:

sudo apk add gcc python3-dev musl-dev linux-headers
pip install --no-binary :all: psutil

Windows

In order to build / install psutil from sources on Windows you need to install Visua Studio 2017 or later (see cPython devguide's instructions). MinGW is not supported. Once Visual Studio is installed do:

pip install --no-binary :all: psutil

macOS (build)

Install Xcode then run:

pip install --no-binary :all: psutil

FreeBSD

pkg install python3 gcc
python3 -m pip install psutil

OpenBSD

export PKG_PATH=http://ftp.eu.openbsd.org/pub/OpenBSD/`uname -r`/packages/`uname -m`/
pkg_add -v python3 gcc
pip install psutil

NetBSD

Assuming Python 3.11 (the most recent at the time of writing):

export PKG_PATH="http://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/`uname -m`/`uname -r`/All"
pkg_add -v pkgin
pkgin install python311-* gcc12-* py311-setuptools-* py311-pip-*
python3.11 -m pip install psutil

Sun Solaris

If cc compiler is not installed create a symbolic link to gcc:

sudo ln -s /usr/bin/gcc /usr/local/bin/cc

Install:

pkg install gcc
pip install psutil

Troubleshooting

Install pip

Pip is shipped by default with Python 2.7.9+ and 3.4+. If you don't have pip you can install it with wget:

wget https://bootstrap.pypa.io/get-pip.py -O - | python3

...or with curl:

python3 < <(curl -s https://bootstrap.pypa.io/get-pip.py)

On Windows, download pip, open cmd.exe and install it with:

py get-pip.py

"pip not found"

Sometimes pip is installed but it's not available in your PATH ("pip command not found" or similar). Try this:

python3 -m pip install psutil

Permission errors (UNIX)

If you want to install psutil system-wide and you bump into permission errors either run as root user or prepend sudo:

sudo pip install psutil
