Trouble with develop build in py 3.4 in osx?

[Nick Eubank]

Hi All,

Try to do a development build with 3.4 (have successfully managed in 2.7). 

I git cloned; python setup.py build_ext --inplace; python setup.py develop. 

Anaconda seems convinced I have cython 0.22.1 installed, and got no errors. 

But when I try and import pandas I get: 

import pandas as pd

Traceback (most recent call last):

  File "<ipython-input-2-af55e7023913>", line 1, in <module>

    import pandas as pd

  File "/Users/Nick/github/pandas/pandas/__init__.py", line 13, in <module>

    "extensions first.".format(module))

ImportError: C extension: 'hashtable' not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace' to build the C extensions first.

Suggestions?

Thanks!

Nick

Confirming it does seem to have been built, this is the output from python setup.py build_ext --inplace:

pandas(master)$python setup.py build_ext --inplace

Thanks to stackoverflow: python setup.py build_ext --inplace --force

The "--force" seemed to do the trick.
