Path error GRASS plugin QGIS 3.14

[Proutbill]

MAC OS 10.15.4 and QGIS 3.14.
Grass Plugin couldn't be found: original path was tied to QGIS 3.12 instead of 3.14>>
/Applications/QGIS3.12.app/Contents/Resources/grass7
Good path is /Applications/QGIS3.14.app/Contents/Resources/grass7

@Proutbill is this a suggestion for a patch? a bug report? else?

[Proutbill]

Yes it was a suggestion for a bug, but I couldn’t change the label/tag. Sorry about that. I just wanted to help people who might face the same issue!

@Proutbill what installer have you used?

[Proutbill]

The one native in my mac. And the files download from QGIS website.

@PeterPetrik ping(?).

[PeterPetrik]

can you try with clean profile? GRASS path can be saved in your preferences. also please try grass from nightly2 builds https://qgis.org/downloads/macos/nightly2/

[Proutbill]

Sorry, my computer skills are limited. I just wanted to report a problem. I have no idea what you are talking about. I downloaded a package, installed it. Grass Plugin wouldn’t work and I had an error message about the path. When I went in the settings I saw that the path was written for another version of QGIS (3.12 and I had 3.14). I fixed the path. Sorry I can’t be more helpful. I went on several forums. And a lot of people are experiencing this problem. I just wanted to help them.

settings > user profiles > new profile

[DelazJ]

From the one-click installer, I had 3.10 installed (and next to it) 3.14. My default profile for 3.14 is showing 3.10 in the "Grass7 path" and "doc path". A new user profile shows 3.14 paths.
I guess paths are not updated while installing a new version.

[PeterPetrik]

I think paths are stored in user profile, and in new profile they are guessed from the installation dir. So I do not think this is bug as such since you can set your GRASS dir to custom one .?.

it's tricky we had similar problems in the past with Processing and SAGA, GRASS paths stored at user level and not changed when installing newer versions... not sure how to classify this.

[PeterPetrik]

workaround: go to Menu->Settings->Options->Processing(left)->Providers->Grass->set GRASS7 folder to /Application/QGIS.app/Contents/MacOS/grass78 or where you installation points to

[PeterPetrik]

Interestingly GRASS_FOLDER is only and only used on MacOS. I imagine it is some workaround for previous issues.

[dkav]

Still not working on qgis_nightly2_master_20200922_013400. Here is the error:

GRASS init error : GRASS was not found in 'INVALID/S/qgis-deps-0.5.4/stage/grass78' (GISBASE), provider and plugin will not work.

[PeterPetrik]

@dkav is this clean profile? also any change you have GISBASE in your environment somewhere (in terminal write env | grep GISBASE)? Can you upen QGIS Python console and type

import os
os.getenv('GISBASE')

[dkav]

Yes, clean profile. No GISBASE environmental settings via shell. Similarly, no value with getenv.

[PeterPetrik]

@dkav but GRASS in processing toolbox is present, only GRASS plugin is not ready, right?

can you try to run ln -s ./grass78 /Applications/QGIS.app/Contents/MacOS/grass and let me know if it works as expected? i will fix in the packager if that works.

[dkav]

Processing toolbox is crashing the application. See #38960.

[PeterPetrik]

What MacOS version do you have?

[Proutbill]

Mac os 10.15.4 I'm having another problem. I fixed the path so I can open grass and create a new mapset, but I can't import any layer in the mapset using the browser.

MacOS - 10.15.6. Creating the symbolic link resolved the issue.

Not sure if this is related or if I am conflating other issues, but I got the following error when loading a GRASS raster while testing. (Vector layer loaded.)

2020-09-22T13:13:54 CRITICAL Invalid Layer : GRASS provider Cannot get projection
Cannot find module /Applications/QGIS.app/Contents/MacOS/lib/qgis/grass/modules/qgis.g.info7

Which may be related to QGIS on startup complaining about missing projdb (or maybe this has nothing to do with projections). From Terminal:

proj_create_from_database: Cannot find proj.db

proj_get_authorities_from_database: Cannot find proj.db

[PeterPetrik]

what is qgis.g.info7 ? I cannot find anything with such name in qgis/QGIS not OSGeo/GRASS repositories?

for proj issue, can you follow #38919?

import os
os.getenv('PROJ_LIB')

and check if such folder exists with proj.db?

Re qgis.g.info7 - I have no idea. I found a reference to it on #31397 and here QGIS/ms-windows/osgeo4w/package.cmd

[dkav]

Re qgis.g.info7, on the qgis_nightly2_master_20200923_133843.dmg build the error reported when loading a raster via the Browser panel is:

[PeterPetrik]

@dkav can you write me steps how to reproduce it?

[dkav]

I just double clicked on a GRASS raster in the browser window. You will need a GRASS database setup with raster to replicate. (Same error on 3.14.)

[dkav]

Just to double check, I imported a different raster into a GRASS DB and the same problem arose. I was able to open both rasters in the GRASS GUI (on Windows).

[drf5n]

@dkav but GRASS in processing toolbox is present, only GRASS plugin is not ready, right?

can you try to run ln -s ./grass78 /Applications/QGIS.app/Contents/MacOS/grass and let me know if it works as expected? i will fix in the packager if that works.

In what directory do you intend this symbolic link to be made? In my QGIS 3.16.0 install I have these:

$ ls -lad /Applications/QGIS.app/Contents/Resources/gr*
drwxr-xr-x@  6 drf  admin  192 Oct 26 11:21 /Applications/QGIS.app/Contents/Resources/grass
drwxr-xr-x@ 23 drf  admin  736 Oct 27 15:30 /Applications/QGIS.app/Contents/Resources/grass78

...and I'm getting the "stderr: dyld: Library not loaded: @rpath/libgrass_gis.7.8.dylib" error as in @dkav's comment: #38595 (comment).

[dkav]

In addition to the raster issue, the following error is logged in MacOS Crash Reports when opening (successfully) a GRASS vector layer.

[dkav]

This may confuse matters but the errors reference in my most recent comment and my earlier comment are independent of the GRASS plugin. The errors are reported if the GRASS plugin is enabled or disabled.
