capistrano错误消息：请安装pg适配器：`gem install activerecord-pg-adapter`（无法加载此类文件- [英] capistrano error msg: Please install the pg adapter: `gem install activerecord-pg-adapter` (cannot load such file --

问题描述

我正在使用capistrano并收到以下错误消息：

I am using capistrano and get this error message:

Please install the pg adapter: `gem install activerecord-pg-adapter` (cannot load such file -- active_record/connection_adapters/pg_adapter)

我已经删除了gem' pg（来自我的Gemfile和捆绑安装 d）。我的Gemfile.lock中没有pg宝石。我也将生产数据库更改为sqlite3适配器。为什么Rails 3.2 / Capistrano / Bundler要求这样做？我没有使用它，也没有在Gemfile.lock中使用它，该如何解决？我在正在发生这种情况的服务器上使用ubuntu 12.04。

I have removed the gem 'pg' from my Gemfile and bundle installd . I don't see the pg gem in my Gemfile.lock. I have also changed my production db to a sqlite3 adapter. Why is Rails 3.2 / Capistrano / Bundler asking for this? I'm not using it and not in Gemfile.lock and how do I resolve it? I am using ubuntu 12.04 on server that this is happening on.

thx

另外，当我运行它告诉我要运行的内容时，我得到了：

Also, when I run what it tells me to run, I get:

deploy@oahu:~$ gem install activerecord-pg-adapter
ERROR:  Could not find a valid gem 'activerecord-pg-adapter' (>= 0) in any repository

database.yml

database.yml

development:
  adapter: sqlite3
  database: db/development.sqlite3

# Warning: The database defined as "test" will be erased and

test:
  adapter: sqlite3

推荐答案

检查您的数据库.yml 。当Postgres的正确适配器是 postgresql 时，您可能会在其中输入一个名为 pg-adapter 的条目。如果您删除或替换了它，那应该可以。

Check your database.yml. You probably have an entry in it called pg-adapter, when the correct adapter for Postgres is postgresql. If you remove or replace that, this should work.
