为什么捆绑会忽略“gem 'pg'”？

Question

正在工作

不知道发生了什么。在 linux 机器上构建 gemfile.lock 并将其移动。有丢失的东西，运行捆绑安装，工作。

Bundle 忽略了我在 Gemfile 中包含的“pg”gem。通过安装 pggem install pg工作正常，当我使用gem list --local.

宝石档案：

source 'http://rubygems.org'

gem 'rails' 
gem 'pg'

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)

尝试删除“gemfile.lock”然后重新运行bundle install？
