rake db 命令在生产服务器上不起作用
rake db commands not working on production server
我刚刚使用 postgres 数据库设置了我的生产服务器，将环境更改为生产环境并 运行 bundle install --deployment。我还在我的服务器上设置了 postgres 用户并创建了必要的数据库。
当我 运行 rake db:schema:load 我得到以下错误：
$ rake db:schema:load
-- enable_extension("plpgsql")
rake aborted!

Tasks: TOP => db:schema:load
(See full trace by running task with --trace)
rake db:migrate、rake db:create 和 rake db:drop 返回了类似的错误。
我的 database.yml 文件如下所示：
default: &default
adapter: postgresql
encoding: unicode
pool: 5
development:

production:

我该怎么做才能修复此错误并使架构加载正常工作？
由于返回的错误表明您正在尝试使用错误的用户登录，这里的问题似乎是您没有正确设置 Rails 环境。
尝试 运行 这样的命令 RAILS_ENV=production bundle exec rake db:schema:load。
您的数据库似乎未配置为允许您的用户访问它。将 Rails 排除在等式之外并使用 psql 尝试使用 database.yml 文件中的信息连接到数据库。所以像...
psql -h localhost -U example_production
开始工作。那么Rails应该没问题。您可能需要调整 PostgreSQL 或您的 database.yml 以便他们同意 user/password/host 设置。
我刚刚使用 postgres 数据库设置了我的生产服务器，将环境更改为生产环境并 运行 bundle install --deployment。我还在我的服务器上设置了 postgres 用户并创建了必要的数据库。
