Installation issue with python 2.7

[bscalzo]

I currently have anaconda with python 2.7 on my PC.
I've tried to install the package using

conda install -c moble quaternion

but this leads to the following error:

UnsatisfiableError: The following specifications were found to be in conflict:

• python 2.7*
• quaternion -> python 3.5*
  Use "conda info " to see the dependencies for each package.

Does the package not work with python 2.7 alone?

Many thanks.

When you say "PC" I'm guessing you mean Windows. Is that right? The conda build on windows is broken; it uses appveyor, which does not particularly support python/conda. And I don't have access to any Windows machines, so I can't do it myself. I'll add a note to the README saying that conda isn't really supported on Windows.

But you should be able to do it with

pip install numpy numpy-quaternion

[Note that this should use the version of pip that exists inside conda, so it won't go installing things outside of your conda directories.]

If this fails, you'll have to just do it manually, by downloading the repository and running python setup.py install from inside of the directory that you get.

Let me know what works for you.

Oh, and you might have to do

conda install pip numpy scipy numba

Yes I have windows. I've tried the various installation methods suggested but all of them lead to this problem:

Building msvcr library: "C:\Users\User1\AppData\Local\Continuum\Anaconda2\libs
libmsvcr90.a" (from C:\windows\winsxs\amd64_microsoft.vc90.crt_1fc8b3b9a1e18e3b_
9.0.21022.8_none_750b37ff97f4f68b\msvcr90.dll)
error: [Error 2] The system cannot find the file specified

I believe this has nothing to do with numpy_quaternion though.

Yeah, unfortunately it's a C module, so it has to be compiled. And since I can't do it, it has to be left to the user — which is apparently when things get tricky on Windows. But that's beyond my scope. Sorry. The only thing I can suggest is maybe just run conda update --all, in case it's a bug that's been fixed.

In issue #73, I realized what the problem is: an old conda build from when 3.6 wasn't even out yet. I've removed all the old Windows builds, so anyone on Windows will need to install manually, or could try pip. I'll mention that in the README.

[moble]

Actually, I just realized that this was already covered in the README.

The current version is now available for Windows (and Linux and macOS) via conda-forge
