The majority of the Raspberry Pi software packages used in the book have been installed
and configured using apt-get and pip. Useful commands have been given for each in the following sections.
The following are the useful commands for APT (this is pre-installed by default on Raspbian):
- Always update the package list to obtain the latest versions and programs before installing a package with the
sudo apt-get updatecommand - Find software by searching for any packages that include the
<searchtext>command in the package name or description usingsudo apt-cache search <seachtext> - Install software with a particular
<packagename>usingsudo apt-get install <packagename> - Uninstall a particular software package using
sudo apt-get remove <packagename> - Display the currently installed version of a software package using
sudo apt-cache showpkg <packagename>
If you want to install a specific version of a software package, use sudo apt-get install <package name>=<version>
Note
If you need to use the packages on a system without internet access, you can use the following command to download the packages (and their dependencies) to the specified directory:sudo apt-get -o dir::cache::archives="<target_directory>" -d -y install <package name>
You can see the details of additional commands by running sudo apt-get and sudo apt-cache. Alternatively, they are listed by reading the manual pages using the man command, the man apt-get command, and the man apt-cache command.
Useful commands for Pip (this is not usually pre-installed on Raspbian) are listed as follows:
- To install Pip or Python 3, use the
sudoapt-get install python3-pipcommand - Install the required package using
sudo pip-3.2 install <packagename> - Uninstall a particular package using
sudo pip-3.2 uninstall<packagename> - To find out the version of an installed package, use
pip-3.2 freeze | grep <packagename> - Install a specific package version using
sudo pip-3.2 install <packagename>==<version>
For example, to check the version of Pi3D installed on your system, usepip-3.2 freeze | grep pi3d.
To replace the installed version of Pi3D with Version 2.13, usesudo pip-3.2 uninstall pi3d and sudo pip-3.2 install pi3d==2.13.
