ERROR 1: PROJ: proj.db contains DATABASE.LAYOUT.VERSION.MINOR = 0 whereas a number >= 2 is expected.

Hi every one,

I am getting the next Error message when I run a python process

ERROR 1: PROJ: proj_create_from_database: C:\Program Files\PostgreSQL\13\share\contrib\postgis-3.2\proj\proj.db contains DATABASE.LAYOUT.VERSION.MINOR = 0 whereas a number >= 2 is expected. It comes from another PROJ installation.

I installed pyproj from pypi and the code where I tranform a coordinates from utm to gcs is this.

inProj = CRS.from_epsg(int(f"326{zona}"))
outProj = CRS.from_epsg(4326)
transformer = Transformer.from_crs(inProj, outProj)

Anybody knows how to solve this issue?

os: windows 10
python 3.9
pyporj version: 3.3.0,
postgres 13
postgis version: 3.2

You are have multiple versions of PROJ installed and the incorrect database is being found. Here are debugging suggestions: https://pyproj4.github.io/pyproj/stable/gotchas.html#internal-proj-error-sqlite-error-on-select

Please set the environment variable PROJ_LIB to the right database (or directory). For example:

$ echo $PROJ_LIB
C:\Program Files\PostgreSQL\14\share\contrib\postgis-3.2\proj << This is another database installed in my computer

My most recent installation of pyproj exists in C:/myprojects/virtualenvs/p310/Lib/site-packages/pyproj.

Therefore I must set PROJ_LIB to:
$ export PROJ_LIB=C:/myprojects/virtualenvs/p310/Lib/site-packages/pyproj/proj_dir/share/proj

I hope this helps.
