# 1. Installation and troubleshooting

This plugin runs with QGIS 3.0 and above.

On Microsoft Windows, QGIS includes all the software dependencies needed by the plugin.

On macOS and Linux, please make sure that Matplotlib with Qt5 backend is installed.

On macOS:

    $ python3 -m pip install --upgrade pip
    $ python3 -m pip install --upgrade matplotlib

On Ubuntu (Debian and similar):

    $ sudo apt install python3-matplotlib

On Fedora and similar:

    $ sudo dnf install python3-matplotlib python3-matplotlib-qt5

On macOS make sure to run the script located under /Applications/Python X.Y/Install Certificates.command, after Python has been installed, to update the SSL certificates bundle.

On Fedora, please follow these instructions.

The plugin can be installed using the QGIS Plugins Manager, that is accessible through the QGIS menu as Plugins -> Manage and install plugins. Please note that the Settings of the Plugins Manager contain a checkbox to Show also experimental plugins. If that option is checked, the latest version of the plugin that is marked as experimental will be available for installation. Otherwise, the latest stable version will be installable.

Note

The latest stable version of the plugin is compatible with the Long Term Support version of the OpenQuake engine, whereas the latest experimental version of the plugin is aligned with the latest version of the OpenQuake engine.

Experimental versions contain new functionalities that may have not been properly tested yet, and that could cause the plugin or QGIS to break or to behave unexpectedly.

Some users reported issues about upgrading the plugin to its latest version. We recommend to reinstall the plugin instead, in order to make sure the new installation is done in a clean folder.

## 1.1. How to run tests and build the documentation

Tests run on a QGIS docker container based on Ubuntu Xenial (16.04LTS), launching one of the following commands from the svir directory:

    $ ../scripts/run_unit_tests.sh
    $ ../scripts/run_integration_tests.sh

The user manual, both in the html and pdf versions can be built by the same QGIS docker container running the following command from the svir directory:

    $ ../scripts/make_doc.sh
