Problemi nell'installazione di pg gem

Question

Cercare di installare la gemma pg mi dà errori.

Sto usando Ruby 1.9.3-p125 costruito utilizzando rbenv/ruby-build. Ho installato PostgreSQL usando il programma di installazione one-click. Sono in grado di connettermi al DB usando pgAdmin. Sono a corto di idee.

% gem install pg                                                  ~ 
Building native extensions. This could take a while... 
ERROR: Error installing pg: 
    ERROR: Failed to build gem native extension.

Answer 1

Non è sicuro quale dei seguenti passaggi abbia finalmente risolto il problema. Ma dato che mu è troppo corta, il problema era mescolare binari a 32 bit e 64 bit.

• prima, ho installato questo 64-bit version of PostgreSQL

• secondo, ho disinstallato qualsiasi vecchio installazione Homebrew OpenSSL

  $ birra disinstallazione openssl

• 3rd, ho installato il 64-bit versione di OpenSSL con Homebrew

  $ brew installare --64 bit openssl

• Infine, quando si installa la gemma pg, ho cambiato il LDFLAGS per puntare alla versione a 64 bit di OpenSSL

  $ gem install pg - --with-LDFLAGS = '- L/usr/local/Cantina/openssl/0.9.8s'
