为什么bundle忽略“gem'pg'”？

Question

当前正在工作

不知道发生了什么事。 在linux中创建gemfile.lock并将其移动。失踪的东西，跑捆绑安装，工作。

Bundle忽略了我在我的Gemfile中包含的“pg”gem。安装pg通过gem install pg工作正常，并且当我使用gem list --local时显示。

的Gemfile：

source 'http://rubygems.org' 

gem 'rails' 
gem 'pg' 

bundle install（无PG）：

Using thor (0.18.1) 
Using railties (3.2.13) 
Using rails (3.2.13) 
Your bundle is complete! 
Use `bundle show [gemname]` to see where a bundled gem is installed. 

bundle show pg：

Could not find gem 'pg'. 
Did you mean pg? 

gem list --local（PG存在）：

另外，如果我尝试运行rails s，rake db:create，等等，我得到：

rake aborted! 
Please install the postgresql adapter: `gem install activerecord-postgresql-adap 
ter` (pg is not part of the bundle. Add it to Gemfile.) 

Tasks: TOP => db:create 
(See full trace by running task with --trace)

Bundler version 1.3.5 

Answer 1

尝试删除您的 “Gemfile.lock的”，然后重新运行bundle install？

Answer 2

尝试删除Gemfile.lock并运行bundle check以查看当前安装的gem是否满足Gemfile中列出的依赖项。
