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 whish to build & install psutil from sources, keep reading.
Ubuntu / Debian:
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
In order to install psutil from sources on Windows you need Visual Studio (MinGW is not supported). Here's a couple of guides describing how to do it: link and link. Once VS is installed do:
pip install --no-binary :all: psutil
Install Xcode then run:
pip install --no-binary :all: psutil
pkg install python3 gcc python3 -m pip install psutil
export PKG_PATH=http://ftp.eu.openbsd.org/pub/OpenBSD/`uname -r`/packages/`uname -m`/ pkg_add -v python gcc 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 pip install psutil
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
Pip is shipped by default with Python 2.7.9+ and 3.4+. If you don't have pip 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 with:
py get-pip.py
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
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
