apk add proj installed PROJ sucessful, but I can‘t get PROJ_DIR

What happens when you run which proj?

[maynewong]

which proj

can't get proj location

/code # which proj
/code #

[snowman2]

Hmmm, seems like you will need to manually find where PROJ was installed then.

What about echo $PROJ_LIB?

[maynewong]

@snowman2

can’t get $PROJ_LIB

/code # echo $PROJ_LIB

only find proj in there paths:

/usr/share # find / -mtime -5 | grep proj
/usr/lib/libproj.so.15
/usr/lib/libproj.so
/usr/share/proj
/usr/include/proj

[snowman2]

This may not work without the proj executable, but you can try: PROJ_DIR=/usr/ pip install pyproj

apk install proj successful, but did not generate the executable file

[snowman2]

is there a proj-bin package?

[maynewong]

@snowman2, found the solution by install proj-util, Thanks

apk add proj-util

/code # which proj
/usr/bin/proj

[snowman2]

@maynewong I am going to assume that you were able to successfully install pyproj. If you are still having issues, feet free to reopen and post comments.
