library dfftpack has Fortran sources but no Fortran compiler found #3

Closed tomdeschamps closed 11 years ago

tomdeschamps commented 11 years ago

Hi

I tried to use this buildpack today on heroku Cedar stack. After installing it for an existing app using 

   heroku config:set BUILDPACK_URL=https://github.com/dbrgn/heroku-buildpack-python-sklearn/

I got the following error

       building 'dfftpack' library

       error: library dfftpack has Fortran sources but no Fortran compiler found

       ----------------------------------------
       Command /app/.heroku/python/bin/python -c "import setuptools;__file__='/tmp/pip-build-u39185/scipy/setup.py';exec(compile(open(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-IeB5XN-record/install-record.txt --single-version-externally-managed failed with error code 1 in /tmp/pip-build-u39185/scipy
       Storing complete log in /app/.pip/pip.log

 !     Push rejected, failed to compile Python app

Any idea what might be going on there? Before that I had the error described in issue #2

Did you convert an existing app to this buildpack or are you trying to create a new app?

tomdeschamps commented 11 years ago

I converted an app with

heroku config:set BUILDPACK_URL=https://github.com/dbrgn/heroku-buildpack-python-sklearn/

See discussion in #2. You need to use one of the provided binary versions of Numpy and SciPy, otherwise it won't work because there are no precompiled versions around, but no Fortran compiler either.

Hi

I am not sure to understand how we can prevent the script from using the cached binaries instead of the precompiled ones available on https://github.com/wyn/npscipy-binaries/ The program which controls that (in bin/steps/numpy-scipy) seems to check to see if there are numpy or scipy already installed and in case they are, then uses them instead of replacing them. Could you let me know how to use properly the script to make that work? Thanks

dbrgn commented 11 years ago

Hm, do you want to upgrade Scipy? Or what exactly is the problem?

A workaround would be to re-create the Heroku app. Tests with a new Heroku App and this buildpack have always succeeded for me.

If you manage to fix the issue, feel free to post a pull request. I don't currently have a Heroku app where I could reproduce the issue.

Hi, does anyone kown what's happing here? I'm installing surprise on a windows platform with python3.6

Hi @RosyRomance, this buildpack is not maintained anymore (as seen in the README).
