problem pip installing under msys2

[tjwilli58]

Installation method/steps

• Installation method: pip
  I also tried downloading the wheel from Christoph Gohlke , but I got

ERROR: pyproj-2.6.0-cp37-cp37m-win_amd64.whl is not a supported wheel on this platform.

• How did you install PROJ? Where is it installed?
  I didn't. I was hoping pip would handle that.

• Please provide all commands/steps you used to install pyproj and PROJ.

pip install pyproj --no-color

Environment Information

• pyproj version you are attempting to install
  2.6.0

• PROJ version (Execute proj command and give version here.)

• Python version (python -c "import sys; print(sys.version.replace('\n', ' '))")
  3.7.4 (default, Aug 15 2019, 18:17:27) [GCC 9.2.0 64 bit (AMD64)]

• Operation System Information (python -c "import platform; print(platform.platform())")

$ python -c "import platform; print(platform.platform())"
Windows-10-10.0.18362-SP0

Result of pip install:

$ pip install pyproj --no-color

I guess the bottom line is, how do I get this installed under msys2 (MINGW64)

$ uname -a
MINGW64_NT-10.0-18362 TIM-ACER-E15 3.0.7-338.x86_64 2019-07-11 10:58 UTC x86_64 Msys

I would recommend trying conda if it an option for you (instructions).

Otherwise, I wonder if you would have better luck posting this on one or both of these sites?

• stackoverflow.com

I'd like to use conda , but there are other packages I need for my application like gstreamer Notice that this isn't built for Windows. I've tried to modify the recipe to get this built, but gave up. Not my expertise.

pyproj is probably overkill for what I need to do, All I really need is to be able to convert Lat/Long dectimal degrees to DMS (degree,minute,second) and back, and also convert to UTM.

There is a python utm module on :PyPi, and I'm looking at that, but I saw a post about Inaccuracy of the UTM to/from lat, lon conversion . One of the reponses on that thread was to replace utm with pyproj. The error in converting back and forth is on the order of centimeters, so I may just say that's good enough.

@tjwilli58, you could also see if pyproj==1.9.6 works for you.

@snowman2 , I tried it, but I have the same problem installing this on msys2.
I found something on stackoverflow that works for me.
That, and the utm module on PyPi.

Thanks,

Actually, geopy works for me.

pt=geopy.Point(39.332876, -76.294984)
pt.format()
'39 19m 58.3536s N, 76 17m 41.9424s W'
pt.format(None, min_char='', sec_char='')
'39 19 58.3536 N, 76 17 41.9424 W'
