无法在Mac OS X Yosemite上安装openfst python库

Question

上周我一直在尝试安装openfst python库，但是我被卡住了。我已经在stack overflow和其他网站上阅读了所有类似的问题，但没有一个说明有效。我安装了最新的Xcode，使用

brew install openfst

我也安装了openfst，但是当我想要通过以下代码安装python库时：

pip install openfst

在终端中，我得到：

谁能帮帮我？

Answer 1

我建议在启用Python的情况下从源代码编译OpenFST。这很简单：

wget http://www.openfst.org/twiki/pub/FST/FstDownload/openfst-1.7.2.tar.gz
tar zxvf openfst-1.7.2.tar.gz
cd openfst-1.7.2
./configure --enable-python
make
sudo make install
