Installation errors using Python 3.6

[jdchoi77]

When I tried to install pyfasttext using Python 3.6 on mac and I got a long error message; the followings show the last part of the message:

#defining NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION" [-W#warnings]
    #warning "Using deprecated NumPy API, disable it by " \
     ^
    src/pyfasttext.cpp:611:10: fatal error: 'random' file not found
    #include <random>
             ^
    1 warning and 1 error generated.
    error: command '/usr/bin/clang' failed with exit status 1
    
    ----------------------------------------

It seems like the error is caused by importing random (also give the warning for using the depreciated numpy API). Any hint? Thanks!

The pre installed gcc on Mac OS did not work for me too.
So first you need a more up-to-date gcc compiler.

You can install one with brew:

brew install gcc

after that you have to tell pip which compiler to use by setting a flag:

CC=/usr/local/bin/gcc-7 pip install --no-cache pyfasttext

The path /usr/local/bin/gcc-7 may has to be adjusted.

The solution from @GeorgesAlkhouri almost worked for me, but I also had to specify the C++ compiler path.

This worked:

brew install gcc
# and if needed, 'brew upgrade gcc' to get gcc-7.2

CXX=/usr/local/bin/g++-7 CC=/usr/local/bin/g++-7 pip3 install --no-cache pyfasttext

Georges solution worked for me. But I spent way too much time before stumbling on this...

@hungtr97

use clang instead of gcc or g++:

CXX=/usr/bin/clang CC=/usr/bin/clang pip install --no-cache pyfasttext
