Installation error - Numpy and its headers are required to run setup()

See original GitHub issue

Both installation methods failed on my computer with a fresh conda env. After explicitly installing numpy, then the installation went smoothly. Does numpy need to be strictly declared dependency for titiler? I found this relevant issue.

OS: Manjaro KDE Linux Python version: 3.8

$ pip install -U pip
$ pip install titiler["server"]

# Or from sources
$ git clone https://github.com/developmentseed/titiler.git
$ cd titiler && pip install -e .["server"]

When rio-color 1.0.1 comes out

The issue here is that rio-color doesn’t provide wheels (yet), which means that to install rio-color all installations must build from source. Since it links to Numpy, it needs Numpy’s headers while compiling.

This is a bit of a chicken-and-egg issue because if we define numpy as an installation requirement, it won’t get installed before rio-color is attempted to be installed.

So I believe the correct solution here is to define numpy as a build dependency (or really rio-color should do that, I might make a PR) so that it’s installed before rio-color is attempted to be installed.
