問題分析
RuntimeError: Unsupported compiler -- at least C++0x support is needed!是關鍵錯誤信息，說是編譯器版本至少是C++0x
查看fasttext官網要求是
facebookresearch/fastTextgithub.com
Generally, fastText builds on modern Mac OS and Linux distributions. Since it uses some C++11 features, it requires a compiler with good C++11 support. These include :
- (g++-4.7.2 or newer) or (clang-3.3 or newer)
那問題比較明顯了，是本地沒有g++的原因導致的。
命令行安裝yum install gcc-c++。
安裝成功後查看版本，滿足指定要求
對應的c gcc 和c++ g++ 都沒有 那麼進行安裝即可
yum install gcc-c++
查看下安裝結果
再次安裝fasttext即可
pip install fasttext
