fairseq/clib/libbleu/libbleu.cpp:10:10: fatal error: 'array' file not found

I have successfully installed pytorch 0.4.0. on mac.

import torch
print(torch.__version__)
0.4.0a0+0b17f4b

But I got an error when I type "python setup.py build". How to fix it?

Fixed. Added '-mmacosx-version-min=10.11' to extra_compile_args in setup.py.
extra_compile_args=['-std=c++11', '-mmacosx-version-min=10.11'],

Still encountered error on my mac

changing `libbleu.cppp'

#include <array> => #include <tr1/array> fixed it for me

This happened for me when running pip install fairseq on my Mac. I ran export CFLAGS='-stdlib=libc++ and then pip install fairseq completed successfully.
