Building pywt on ubuntu

Question

I have problems building pywt from source on Ubuntu.

When I run python setup.py build, I get the following error:

running build
running build_py
running build_ext
Cython is not installed. Using compiled file: src/_pywt.pyx
building 'pywt._pywt' extension

gcc: error: src/_pywt.c: No such file or directory
gcc: fatal error: no input files

When I run cython --version I get the following output:
