[MB2 feedback] `checkMin()` and `qgis_configure()` fail

[16EAGLE]

Nice package!

Installation works fine, but if I try to run checkMin(), I get the following error:

> mini <- checkMin(dsm, tracks, export = FALSE, dist_cross = 1, profile_length = 1, dist_cross_points = 0.05, st_dev = 0.06)
#> Error in `assert_qgis()`:
#> ! The 'qgis_process' command-line utility was either not found or
#> did not fulfil the needs to build the package cache.
#> Please run `qgis_configure()` to fix this and rebuild the cache.
#> See its documentation if you need to preset the path of qgis_process.
#> Run `rlang::last_trace()` to see where the error occurred.

Running qgisprocess::qgis_configure() afterwards does not help:

Do you have any idea how I could solve this to get your functions to run?

Hey Jakob, thanks for the feedback and sorry for the late reply. I was trying to figure out why it won't work. I first thought it's the QGIS version, but I just checked Maidenhead (before I used Prizren) and it works there too on my Windows. Maybe run qgisprocess:::qgis_reconfigure(), it could show the cause of the problem.

Then also please check with qgis_path() if this is set correctly (something like: "C:/Program Files/QGIS 3.36.2/bin/qgis_process-qgis.bat") What happens if you type qgis_plugins()? You could enable plugins by qgis_enable_plugins().

Note to myself: better creating a package independent of qgisprocess. When I started, I was not aware of such issues. ;(

Hope it gets solved with that, let me know.
