QGIS cannot locate procedure entry point after activation of plugin

[EddyGC61]

Hi, I attempted to install Release 1.3.1 RC3 in accordance with the instructions. It all seemed to go very well until I checked on the plugin to activate it in QGis.

I received the error (see screen grab) it could not locate a procedure entry point and the following error description.

I am not a coder, but an end user of QGIS. Could I have missed something in the installation? Any help would be appreciated.

Couldn't load plugin 'Geo-SAM'

rasterio.errors.CRSError: The EPSG code is unknown. PROJ: proj_create_from_database: C:\OSGeo4W\share\proj\proj.db contains DATABASE.LAYOUT.VERSION.MINOR = 3 whereas a number >= 4 is expected. It comes from another PROJ installation.

Hi @EddyGC61

This is the same issue as #57 (comment). You can try applying the solution suggested there to see if it resolves the problem.

Thank you for that assist. I did try as you suggested, but with the same error resulting.

What is the process of manually updating the proj.db? I viewed the file and it is not text format. Do I overwrite with a file from elsewhere, and where would I obtain that file?

Again, thank you for your assistance.

Hi @EddyGC61

The issue stems from having multiple GIS software installations, which can result in multiple versions of PROJ being installed and lead to inconsistencies in the proj.db files. I haven’t encountered this issue myself, so I don’t have direct experience solving it. Below are a few potential fixes you can try:

1. Search for Multiple proj.db Files
   Use the Everything search tool to locate all proj.db files on your system. If you find multiple instances, try setting the PROJ_DATA environment variable to point to a another proj.db file and see if that resolves the issue.

2. Reinstall pyproj and rasterio
   Delete the existing proj.db file, then reinstall pyproj and rasterio with the following command:

   pip install pyproj rasterio --force-reinstall

3. Uninstall Other GIS Software
   If you have multiple GIS applications installed, try uninstalling all of them, then reinstall pyproj and rasterio using the command above.

4. Install QGIS via Conda
   If the issue persists, try installing QGIS via Conda and check whether the Conda version of QGIS encounters the same problem. For installation and usage instructions, refer to this guide: QGIS Installation with Conda.

If you manage to resolve the issue, please share your solution with the community to help others facing similar problems. Good luck!

Thank you for the extra information. I attempted all your suggestions without luck. I have fired up an older PC to see if I am able to get it to work on that. Thank you again.

Hi @EddyGC61, this seems to be an installation issue of QGIS. You can try to clean reinstall following a complete uninstallation.
You can refer to the following link to uninstall. https://courses.spatialthoughts.com/uninstall-qgis-ltr.html
Good luck.

[EddyGC61]

I've already tried a clean install (uninstalled using OSGeo4W and then removed everything I could find relating to QGIS and OSGeo4W including references within the registry) and still got the same error message.

It will be something simple and easily overlooked.

PS. I couldn't get it to work on another PC (also after a clean install). The two PCs have similar software loaded, and I did notice a proj.db in the Jamovi directory on the second PC which I removed with every other copy I could find after removing QGIS from the system, installed QGIS from OSGeo4W, reinstalled pyproj and rasterio, installed Geo-SAM and got the same error message.

[coolzhao]

Got it. We will try to figure out what the problem is here. Thanks for your feedback and detailed information.

[EddyGC61]

Thanks for your help. I hope you are able to resolve it soon.
