[MSNoise] Problem in building the documentation

[cxh757]

I follow http://msnoise.org/doc/installation.html#building-this-documentation to try to build the documentation.


but when I run "make html", it returns :


[cxh at core doc]$ make html
sphinx-build -b html -d .build/doctrees   . .build/html
Traceback (most recent call last):
  File "/home/cxh/anaconda/bin/sphinx-build", line 9, in <module>
    load_entry_point('Sphinx==1.2.3', 'console_scripts', 'sphinx-build')()
  File "/home/cxh/anaconda/lib/python2.7/site-packages/setuptools-5.8-py2.7.egg/pkg_resources.py", line 339, in load_entry_point
  File "/home/cxh/anaconda/lib/python2.7/site-packages/setuptools-5.8-py2.7.egg/pkg_resources.py", line 2456, in load_entry_point
ImportError: Entry point ('console_scripts', 'sphinx-build') not found
make: *** [html] error 1


How can I solve this problem? 
Thanks
