Eu tenho tentado resolver um problema que encontrei ao tentar instalar um pacote python no Lubuntu 17.04.
O pacote é para python 3.5 64bits. É chamado RawPy e depende da biblioteca LibRaw. Instalei a biblioteca LibRaw, mas ao tentar instalar o RawPy, ele não consegue encontrar alguns arquivos da instalação do LibRaw:
lubuntu@lubuntu:~$ sudo -H pip3 install rawpy

Eu verifiquei e os arquivos ausentes existem em usr / local / lib / libraw. Tentei adicionar essa rota usando ldconfig mas isso não funcionou.
O LibRaw parece estar instalado. Quando escrevo ldconfig -p , obtenho:
libraw1394.so.11 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libraw1394.so.11
libraw_r.so.16 (libc6,x86-64) => /usr/local/lib/libraw_r.so.16
libraw_r.so.16 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libraw_r.so.16
libraw_r.so (libc6,x86-64) => /usr/local/lib/libraw_r.so

libraw.so (libc6,x86-64) => /usr/local/lib/libraw.so
E, de fato:

O terceiro local é a pasta de download do código-fonte do GitHub. Eu também compilei a última versão do código, mas não funcionou
Existe alguma maneira de explicitamente dizer ao pip para procurar em determinado caminho por dependências? Eu até pensei em mudar a fonte para explicitamente dizer o caminho, mas eu não acho que é a correção adequada.
Alguém tem alguma ideia?
Aviso: sou o desenvolvedor do rawpy.
Não tenho certeza sobre o problema específico que você tem, mas lancei recentemente uma nova versão que fornece pacotes binários (rodinhas) para o Linux (além do Windows e do macOS), portanto não é necessária mais compilação ou instalação manual da libraw. Basta reinstalar o rawpy e ele deve funcionar imediatamente.
Experimente
echo "/usr/local/lib" | sudo tee /etc/ld.so.conf.d/99local.conf
seguido por sudo ldconfig .
Isso é feito nas instruções de instalação para rawpy.
