Re: [Qgis-user] Problems with Plugins

Wed, 11 Feb 2026 01:06:42 -0800 

Hi Nicolas,
the/EO Time Series Viewer Plugin/ is developed by my colleague Benjamin (CC). The plugin is using the /PyQtGraph /package, which recently introduced the *'colorama'* dependency. This explains your error: 

*ModuleNotFoundError: No module named 'colorama' *


The plugin tries to avoid external package installation by shipping 
everything it needs with the plugin, but for now, you need to work 
around this, by installing the *'colorama'* package via PIP using the 
OSGeo4W shell.



Regards
Andreas

Hi Andrea, you will find the original error message that starts all my 
troubles. I can use internet et acces to the plugin server without any 
problem. As nothing I tried enhence my situation, I'll uninstall Qgis 
and remove all profile and regit information linked to Qgis.



I just want to be able to re install Qgis properly to be able tu 
install any plugins, that is not the case at the moment...


Thanks for your tips and advices if you have

Hi Nicolas,

which QGIS version are you using exactly? On which operative system? 
What is the URL and the status of the plugin repositories listed in 
Plugins -> Manage and Install Plugins -> Settings? What happens if 
you click on "Reload repository"? What happens if you browse the 
repository URL using a web browser in the same system? Is QGIS, 
installed in your system, able to connect to any Internet resource 
(e.g. the OpenStreetMap XYZ Tiles server?


Regards.

Andrea
