incapaz de instalar um pacote usando pip

Question

Estou tentando instalar um pacote usando pip dentro de um virtualenv:

pip install fuse-python

mas a saída é

até onde eu sei, há algo errado com o pkg-config e o PKG_CONFIG_PATH

Estou executando o ubuntu 14.04, e a saída de dpkg -l | grep is (então a instalação do meu fusível não é 'muito antiga'):

ii  fuse                                        2.9.2-4ubuntu4                                      amd64        Filesystem in Userspace
ii  gvfs-fuse                                   1.20.1-1ubuntu1                                     amd64        userspace virtual filesystem - fuse server
ii  ifuse                                       1.1.2-0.1                                           amd64        FUSE module for iPhone and iPod Touch devices
ii  libfuse2:amd64                              2.9.2-4ubuntu4                                      amd64        Filesystem in Userspace (library)

ATUALIZAÇÃO: Instalei-o usando o sudo apt-get install python-fuse, mas que o instalou globalmente:

ii  python-fuse       2:0.2.1-9   amd64    Python bindings for FUSE (Filesystems in USErland)

    

Answer 1

Instale sudo apt-get install libfuse-dev e tente novamente. Funciona.
