OSError：未设置`LIBFM_PATH`

Question

我最近安装了libFM并使用pywFM

https://pypi.python.org/pypi/pywFM

我按照说明操作，并将LIBFM_PATH设置为

export LIBFM_PATH=/Users/raon/Dropbox/Python/libfm/libfm/bin/

这是/ bin /文件夹的位置

当我尝试运行上面链接中提供的示例时，出现以下错误：

fm = pywFM.FM(task='regression', num_iter=5)
Traceback (most recent call last):

  File "<ipython-input-14-d2c7380843b8>", line 1, in <module>
    fm = pywFM.FM(task='regression', num_iter=5)

  File "/Users/raon/anaconda2/lib/python2.7/site-packages/pywFM/__init__.py",     line 105, in __init__
raise OSError("`LIBFM_PATH` is not set. Please install libFM and set the path variable (https://github.com/jfloff/pywFM#installing).")

OSError: `LIBFM_PATH` is not set. Please install libFM and set the path variable (https://github.com/jfloff/pywFM#installing).

知道如何纠正LIBFM_PATH（可能是错误的）设置吗？
