Ignoring bcrypt-3.1.7 because its extensions are not built. Try: gem pristine bcrypt-3.1.7 Ignoring bigdecimal-1.2.5 because its extensions are not built. Try: gem pristine bigdecimal-1.2.5 Ignoring ffi-yajl-1.1.0 because its extensions are not built. Try: gem pristine ffi-yajl-1.1.0 Ignoring gem-wrappers-1.2.5 because its extensions are not built. Try: gem pristine gem-wrappers-1.2.5 Ignoring gem-wrappers-1.2.4 because its extensions are not built. Try: gem pristine gem-wrappers-1.2.4 Ignoring pg-0.17.1 because its extensions are not built. Try: gem pristine pg-0.17.1 Ignoring psych-2.0.6 because its extensions are not built. Try: gem pristine psych-2.0.6 Ignoring sqlite3-1.3.9 because its extensions are not built. Try: gem pristine sqlite3-1.3.9 E enquanto é uma solução simples, continua acontecendo. Alguém já se deparou com isso antes?
