Cython Attributeerror: 'module' Object Has No Attribute 'declare'

Compiling .pyx files was working fine but suddenly it started raising error when I type: python setup.py build_ext --inplace I get the error: c:\Python27\cython\helloworld>pyth

Solution 1:

I got the same error when running from a python script:

os.system("python setup.py build_ext --inplace")

while

python setup.py build_ext --inplace

worked from command promt.

The reason was that the name of my test package was "cython"... stupid me

Solution 2:

I have had the same error. Worked on it for one whole day until I have realized that I have followed some blog entry to create a cython.py file in my directory holding some information how to compile. I do not recall where I found this but by removing this file everything works fine

Solution 3:

I'm not sure this helps, but when I got this error I deleted all .pyc files and ran the script again via IDLE (opened in IDLE and clicked F5) and then it worked just fine.
