Installation Failure

[idhidro]

I have been attempting to install PyLEnM and the installation has failed while installing richdem. I am using Python 3.10.1, pip 23.0, setup tools 65.5,and Visual Studio 2022. I have down graded to VS 2019 and have used the --use pep 517 option and the installation still fails. The installation errors are:

DEPRECATION: richdem is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at pypa/pip#8559

"command 'C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\MSVC\14.34.31933\bin\HostX86\x64\cl.exe' failed with exit code 2".

Any suggestions would be appreciated. Thanks.

I got the same exit code 2 issue when installing richdem using Python 3.10.9, Visual Studis 2022, Windows 11. I got the error of C2065 and
C2338

I tries using the solution provided in davisking/dlib#2463 (comment). But it is not working for richdem. Maybe the pybind11 need updated? (#46 (comment))

Not sure if you are still having this issue but I wondered if you tried installing using conda? That has its own issues that I struggled with for quite some time but I finally got it working using the workflow below. It's a bit of a messy solution and there might be a better way of doing it but it worked:

Install Visual studio build tools 2019

• ensure that you install Desktop development with C++ (essential)
• once installed browse to "C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools" (or wherever you installed build tools) and copy the "VC" folder
• Paste the VC folder into "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise"

open up anaconda prompt

• You might want to create and activate a new environment, I did, so if it doesn't work without the new environment try that first.
• conda install -c conda-forge python gdal richdem

Hopefully this works for you.
