MacOs Mojave
Python 3.6.6

[schmmd]

Interesting and a bit surprising. The development team uses MacOS and we test pip install allennlp for every commit to master in our Docker build. I'll try re-creating my conda environment.

As a work-around you could run AllenNLP within Docker.

Relevant: ContinuumIO/anaconda-issues#10135

[schmmd]

I was able to pip install allennlp in a fresh environment just fine on High Sierra. Combined with the issue @matt-gardner linked suggests your error is related to Mojave.

[nityansuman]

@schmmd yes... i strongly believe too.

Got the work around!
conda install allennlp -c pytorch -c allennlp -c conda-forge

[nityansuman]

@matt-gardner thanks!

[schmmd]

I upgraded to Mohave today and did a fresh install of AllenNLP without any problems (including jsonnet). Of course--your mileage may vary ;-)

I got this problem when I run this command....

PackageNotFoundError: Dependencies missing in current osx-64 channels:

• allennlp -> gevent 1.3.5
• allennlp -> pytorch >=0.4.0,<0.5.0 -> mkl >=2018

PackageNotFoundError: Dependencies missing in current osx-64 channels:

I got it by setting the environmental variable MACOSX_DEPLOYMENT_TARGET:
Just run export MACOSX_DEPLOYMENT_TARGET=10.14

conda install allennlp -c pytorch -c allennlp -c conda-forge

When trying to run this command I get the following odd error, which seemingly comes from trying to parse the conda-forge part.

$ conda install allennlp -c pytorch -c allennlp -c conda-forge
Solving environment: failed

CondaValueError: Malformed version string '~': invalid character(s).

@schmmd yes... i strongly believe too.

conda install allennlp -c pytorch -c allennlp -c conda-forge

This worked after creating and activating the conda virtual environment
conda create -n allennlp python=3.6
source activate allennlp
