If you use pip install mpi4py it might work, it installed for me that way.

Hi,

On MacOS, the exact command works for me : conda install mpi4py=3.0.3.
Some SO questions like this suggest installing MS MPI first to make mpi4py work on windows.
Maybe you can try that if not already done. I hope it helps.

Had the same problem on Ubuntu 18.0.4. Solution was to run conda install -c anaconda mpi4pi=3.0.3 instead.

Added a PR here: #28

@zacharyneveu I tried to reproduce in various OS including ubuntu 18.04 but conda install mpi4py=3.0.3 worked fine, referring to pkgs/main/linux-64::mpi4py-3.0.3-py37h028fd6f_0. Are you in 32bit by any chance?

I did see the OP's issue on Windows, but it has a larger issue (of not being supported, see #36 ). I also see in a Windows port they used pip install mpi4py instead, but manually installed MPI.

Thanks, it works for me too

I have the same problem. I installed gtts using pip, but I am using Anaconda Spyder for development, and it doesnt recognise packages Ive installed using pip. When I try to install gtts using Conda I get a message "The following packages are not available from current channels". Hit a brick wall here.

Windows 8 will work.

I use Windows x64, and I searched around on anaconda.org for a working channel.
Apparently, this command still works.
