Installation Error "No module named cymem.cymem" El Capitan, Ananconda, spacy-0.99

I am on Mac OSX El Capitan and using Anaconda with a fresh install of python in my home dir.

MacBook-Pro:anaconda vikram$ which python /Users/vikram/anaconda/bin/python

When running python -m spacy.en.download all I get the error: /Users/vikram/anaconda/bin/python: No module named cymem.cymem

While installing spacy there was a message about possible conflict in cymem package which it automatically resolved.

MacBook-Pro:anaconda vikram$ conda install spacy Fetching package metadata: … Solving package specifications: … Warning: 4 possible package resolutions (only showing differing packages): [u’cymem-1.30-0.tar.bz2’, u’murmurhash-0.24-0.tar.bz2’], [u’cymem-1.30-py27_0.tar.bz2’, u’murmurhash-0.24-0.tar.bz2’], [u’cymem-1.30-py27_0.tar.bz2’, u’murmurhash-0.24-py27_0.tar.bz2’], [u’cymem-1.30-0.tar.bz2’, u’murmurhash-0.24-py27_0.tar.bz2’],

This is some great debugging — we really appreciate this, thanks!

If you just want to get up and running, it seems easier to use pip instead of conda, as it seems our package on conda isn’t correct. While we sort the issue out, I suggest the following:

\1. Start with a clean conda environment

`conda create --name myenv numpy`

The conda create command requires you to specify at least one package to install. I always find this super confusing. The important thing here is that you can’t write spacy! If you do, spacy will be installed from the conda package, when we want to install it from pip.

\2. Activate the environment

source activate myenv

\3. Install with pip

pip install spacy

\4. Install data

python -m spacy.en.download --force all
