Would anyone have any ideas to solve this? Thank you.

Please try the develop branch from GitHub. I'm going to do a release in a couple of days.

pip install Cython

pip install git+https://github.com/nigma/pywt.git@develop

Thank you for your reply. I have tried the develop branch but the same issue happen to me. Look forward to the next release.

Same issue here.  I'm running Enthought Python 7.3, which has Python 2.7 and Cython 0.16.

Trying to build from the Dev branch as suggested above and still get an error.

Quick update...

I was able to download and install the latest version posted to BitBucket (last updated 2012-06-04), but only after an unzip and manual install rather than using easy_install.

Thanks for your work.  Please let us know when the knew release is ready.

The setuptools monkey-patching is giving me a hard time. I have pushed
another change that hopefully will resolve issues related to
installing from git repository.

I have tested it on a couple boxes with virtualenv and
setuptools==0.6c11/distribute==0.6.27:

- Ubuntu 10.04 with Python 2.6 and pip 0.7.2
- Ubuntu 12.04, Python 2.7 and pip 1.1
- Debian wheezy, ditto
- Windows 7 x64, ditto

I have experienced random issues when installing packages from git
with older versions of setuptools, so you may need to do
`pip install --upgrade seuptools` or even better
`pip install --upgrade distribute`.

The setup script should automatically retrieve a proper version of
Cython if necessary (required for dev, the release will bundle all
necessary files like it should). Provided that all system build
utilities and compilers are in place, is should be possible to install
the extension from git using only:

pip install "git+https://github.com/nigma/pywt.git@develop"


Please check if this works and create a ticket on
https://github.com/nigma/pywt/issues including system information and
install command output log for any outstanding issue.


A recent snapshot archive for `setup.py install` is at
https://github.com/nigma/pywt/downloads.

The documentation snapshot is at http://pywavelets.rtfd.org. I'm
focusing on sorting out all outstanding issues and getting a Python 3
port (https://github.com/nigma/pywt/tree/py-3) so there are no new
features or api changes.
