Error during install on MacOS Mojave

[Kensuke-Mitsuzawa]

I encounter the error when I try to install the package on MacOS Mojave.

    gcc -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/Users/kensuke-mi/.pyenv/versions/anaconda3-5.3.1/include -arch x86_64 -I/Users/kensuke-mi/.pyenv/versions/anaconda3-5.3.1/include -arch x86_64 -I/usr/local/Cellar/mecab/0.996/include -I/Users/kensuke-mi/.pyenv/versions/anaconda3-5.3.1/include/python3.7m -c MeCab_wrap.cpp -o build/temp.macosx-10.7-x86_64-3.7/MeCab_wrap.o

Solution

The main reason for the error is that C/C++ compiler is the old version.

So, it's totally OK if you update C/C++ compiler.

1. install the latest compiler with brew install gcc
2. Put new symbolic links into the latest gcc compiler. ln -s /usr/local/bin/gcc-8 /usr/local/bin/gcc and ln -s /usr/local/bin/g++-8 /usr/local/bin/g++
3. put this line in your shell profile file, in my case ~/.bash_profile: export PATH=$PATH:/usr/local/bin
4. refresh your terminal such as source ~/.bash_profile
5. try to install the package again
