[Community] upgrade from 1.2.14

[Harasty, Daniel J]

I see the warning to Windows users of Shapely:

Warning: Windows users: do not under any circumstances use pip (or easy_install) to uninstall Shapely versions < 1.2.17. Due to the way Shapely used to install its GEOS DLL and a distribute or setuptools bug, your Python installation may be broken by an uninstall command. Shapely 1.2.17 will uninstall safely.

I'd like to update to Shapely 1.3. I'm currently using Shapely 1.2.14 (on Windows 7 with Python 2.6 32-bit).

Do I simply use:

pip install shapely --upgrade

to safely avoid the problem mentioned in the Warning?

If not: what is my migration path to Shapely 1.3?

I looked for this info in the Shapely docs but didn't see it; apologies if I overlooked it.

As long as you have a C compiler
and the Cython Python Pacage installed
you should be able to use:

pip install -U shapely

Just don't run the uninstall command and you'll be fine. Btw, I'm not sure
you can pip install shapely on Windows, I think you'll have to manually
download and run an installer .exe.

It should work as long as you have a working compiler environment to build
C extensions et all. It is easier to use a. Preprepared binary though!
