bdist_wheel ne fonctionne pas sous MSYS2

Question

Je tente de créer un package Python à l'aide d'un shell MSYS2 MINGW64 sur une machine virtuelle Windows 7 VirtualBox. Le paquet construit, installe et importe avec succès sur Linux.

je peux construire une roue binaire sous MSYS2 ...

$ python setup.py bdist_wheel 
running bdist_wheel 
running build 
running build_py 
running build_ext 
running build_scripts 
installing to build/bdist.mingw/wheel 
running install 
running install_lib 
running install_egg_info 
running egg_info

Copying stencila.egg-info to /build/bdist.mingw/wheel/./stencila-0.24.0+a67987b-py2.7.egg-info 
running install_scripts

mais est efficace "vide" (manquant compilé l'extension C++ et Python sources) ...

Answer 1

là MSYS2 est un conflit entre avec la traduction de chemin MSYS2 et bdist_wheel. Une solution consiste à spécifier un chemin absoludans un répertoire temporaire de construction en utilisant l'option --bdist-dir (ne devrait pas être « construire » depuis bdist_wheel supprime ce répertoire qui signifie un nouveau chaque fois reconstruisent):

python setup.py bdist_wheel --bdist-dir=$PWD/build-temp
