使用 Python 2.7.12 和 Ubuntu 16.04.2 LTS，我尝试按照@PyFST Setup CMU的说明安装 OpenFst 和 pyfst，但失败并出现错误
注意：候选人需要 16 个参数，提供 15 个参数 错误：命令“x86_64-linux-gnu-gcc”失败，退出状态为 1
并且还尝试了@PyFST Setup OGI，但失败了

错误：命令“x86_64-linux-gnu-gcc”失败，退出状态为 1
看起来 OpenFst 设置正确，因为我能够看到 fst 命令。

但是，当我尝试运行时出现此错误sudo pip install pyfst
...（仅包括错误消息的片段，因为比终端窗口长）

或者我尝试以下方法：
wilson@wilson-300V3A-300V4A-300V5A:~/demo/openfst-1.6.2$ echo "export PREFIX=$(cd; pwd)/prefix" >> ~/.bashrc
wilson@wilson-300V3A-300V4A-300V5A:~/demo/openfst-1.6.2$
wilson@wilson-300V3A-300V4A-300V5A:~/demo/openfst-1.6.2$ echo 'export CPLUS_INCLUDE_PATH=$PREFIX/include:$CPLUS_INCLUDE_PATH
> export LIBRARY_PATH=$PREFIX/lib:$LIBRARY_PATH
> export LIBRARY_PATH=$PREFIX/lib/fst:$LIBRARY_PATH

> export LD_LIBRARY_PATH=$PREFIX/lib/fst:$LD_LIBRARY_PATH

这似乎工作正常
