Rake db操作在read_nonblock中出现EOF错误

Question

我正在使用Postgres数据库设置一个继承的Rails4应用程序(Ruby2.0.0p645)的本地副本。数据库本身运行良好，迁移也没有问题，但是rake db:seed、db:load、db:dump和db:purge都抛出了相同的错误。

我发现这非常令人困惑，特别是因为我能找到的所有涉及read_nonblock的EOF错误都涉及HTTP请求，而我找不到任何理由来解释为什么这些数据库任务会涉及到这一点。

你知道为什么会涉及这些HTTP gem吗？

我的整个database.yml，这似乎是潜在的相关：

development:
  adapter: postgresql
  database: docufyi_development
  username: postgres
  host: 127.0.0.1
  password:
  encoding: utf8
  pool: 5

(对于使用httparty或rest-client的常见gem的建议也很受欢迎。)

你能检查一下初始化器吗?很明显这个问题与RestClient的gem有关。你有没有碰巧在用它？
