Fehler kann 'pg' Juwel auf lokalen Windows 7 nicht laden Ruby on Rails

Question

Ich habe gerade begonnen, Ruby auf Schienen zu lernen. Ich habe pg gem installiert wie unten gezeigt. Und 'pg' ist sowohl in gemfile.lock als auch in gemfile. Es wird jedoch weiterhin ein Fehler angezeigt, "Gem wurde nicht geladen. Füge gem 'pg' zu deiner Gemdatei hinzu."

Ich habe auch versucht, jemandes Rat folgen, löschen Sie die gemfile.lock und re-Bundle. Derselbe Fehler ist aufgetreten.

E:\RoR docs\first_app>bundle show pg 
Could not find gem 'pg'. 
Did you mean pg? 

gemfile:

source 'https://rubygems.org' 

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

Answer 1

Ihre gem Liste zeigt:

pg (0.15.1 x64-mingw32)

Aber Ihre Gemfile.lock zeigt

PLATFORMS x86-mingw32

Ich denke, Ihr Problem bezieht sich auf eine gemischte Plattform (32 Bit (x86) vs 64 Bit (x64))

Versuchen Sie zu investieren legate das.
