発生した問題

mojimojiのインストールでgccエラー

※ここから先は,私の試したことを辿るので,お急ぎの方やサクッと解決法を知りたい方は解決法まとめへお願いします.

かなり省略していますが以下のようにエラーが出ました.

$ pip install mojimoji
...
  ERROR: Command errored out with exit status 1:
...
  mojimoji.cpp:581:10: fatal error: 'ios' file not found
  #include "ios"
           ^~~~~
  1 warning and 1 error generated.
  error: command 'gcc' failed with exit status 1

試した方法

第一段階

調べてみると,まず以下の方法が見つかりました.
参考：https://qiita.com/nkmrtkhd/items/eac5828d031c72446e76

$ cd $HOME
$ git clone https://github.com/studio-ousia/mojimoji
$ cd mojimoji
$ python setup.py install

ウン！やってみよう！

$ python setup.py install
running install
running bdist_egg
running egg_info

      library instead [-Wstdlibcxx-not-found]

#include "ios"
         ^~~~~

^_^
エラーは変わりませんでした.

第二段階

第一段階の後しばらく調べてみたのですが結局変わらず...

方向転換して(と言うか解決した今では当たり前なのかもしれませんが...),mojimojiのエラーとしてではなく,#include "ios"でのエラーを解決する方向で調べると以下のページにたどり着きました.
参考：https://github.com/cleardusk/3DDFA/issues/57

簡単に言えば,Mac使ってるならsetup.pyでextra_compile_args=['-std=c++11', '-D_hypot=hypot', '-stdlib=libc++']にしてみろとのこと.

setup.py
# -*- coding: utf-8 -*-

import io
import sys
from setuptools import setup, Extension

if sys.platform.startswith('win'):
    compile_args = []
    link_args = []
else:
    compile_args = ['-std=c++11']
    link_args = ['-std=c++11']


setup(
    # 省略
)

中身はこんな感じ.
else分のところにcompile_argsがありますね.
これを先ほどのextra_compile_argsに書き換えましょう.

setup.py
# -*- coding: utf-8 -*-

import io
import sys
from setuptools import setup, Extension

if sys.platform.startswith('win'):
    compile_args = []
    link_args = []
else:
    compile_args=['-std=c++11', '-D_hypot=hypot', '-stdlib=libc++'] # New!
    link_args = ['-std=c++11']


setup(
    # 省略
)

注意ですが,変数名もextra_compile_argsにしないようにしてください.
やっちゃうと動きません.私は天才アホなのでやって動きませんでした.

と言う訳で動かしてみます.

えぇ...
もう一度先ほどのIssueをみてみると,下の方に書いてありました.
こう言うのはちゃんと読みましょう.（ブーメラン）
extra_link_args=['-stdlib=libc++', '-mmacosx-version-min=10.9','-std=c++11', '-D_hypot=hypot']もやろうねってことでしたので変更を.

setup.py
# -*- coding: utf-8 -*-

import io
import sys
from setuptools import setup, Extension

if sys.platform.startswith('win'):
    compile_args = []
    link_args = []
else:
    compile_args=['-std=c++11', '-D_hypot=hypot', '-stdlib=libc++'] # New!
    link_args=['-stdlib=libc++', '-mmacosx-version-min=10.9','-std=c++11', '-D_hypot=hypot'] # New!


setup(
    # 省略
)

先ほどと同様にextraはつけないように.

と言う訳でインストールができ,mojimojiが使えるようになりました.
個人的にはかなり詰まったので参考になれば幸いです.
