Ho un server Ubuntu 10.10 su EC2. Ho installato Python 3.1 e ora voglio installare NumPy su di esso. Come lo faccio? Ho provato easy_install-3.1 numpy ma ho ricevuto questo errore:
RefactoringTool: Refactored /tmp/easy_install-MiUli2/numpy-1.5.1/build/py3k/numpy/core/defchararray.py

ValueError: 'build/py3k/numpy' is not a directory
Risposta accettata:
Il codice di questo ramo di numpy sembra includere una correzione.
Ecco uno snippet e i commenti pertinenti :
643 # XXX Hack to get numpy installable with easy_install.
644 # The problem is easy_install runs it's own setup(), which
645 # sets up distutils.core._setup_distribution. However,
646 # when our setup() runs, that gets overwritten and lost.
647 # We can't use isinstance, as the DistributionWithoutHelpCommands
648 # class is local to a function in setuptools.command.easy_install
649 if dist is not None and \
650 repr(dist).find('DistributionWithoutHelpCommands') != -1:
651 return None
652 return dist
Tuttavia, se non vuoi farlo, prova python3.1 setup.py install all'interno della directory in cui hai estratto numpy. Ciò evita il problema easy_install descritto nei commenti al codice.
