Question

我使用postgres（PostgreSQL）9.3.5使用我的Rails（4.0.1）应用程序和Ruby（2.0.0-p451），其中一个迁移看起来像：

class CreateExtensions< ActiveRecord::Migration
    def up
        connection = ActiveRecord::Base.connection
        extensions = %w(fuzzystrmatch hstore plpgsql postgis postgis_tiger_geocoder postgis_topology)
        ext_query = extensions.map {|e| "CREATE EXTENSION IF NOT EXISTS #{e};" }.join
        connection.execute(ext_query)
    end
end

每当我尝试运行迁移文件时，都会收到以下错误：

CREATE EXTENSION IF NOT EXISTS fuzzystrmatch;CREATE EXTENSION IF NOT EXISTS hstore;CREATE EXTENSION IF NOT EXISTS plpgsql;CREATE EXTENSION IF NOT EXISTS postgis;CREATE EXTENSION IF NOT EXISTS postgis_tiger_geocoder;CREATE EXTENSION IF NOT EXISTS postgis_topology;

我使用Homebrew安装了Postgres，不知道我在这里做错了什么？

确保从相同的源和兼容版本安装PostgreSQL和PostGIS。
