Rake任务在本地工作，但不在Heroku上工作

Question

我有一个rake任务，可以将数据加载到我的数据库的表中。我最近对我的架构进行了更改，将它们迁移到heroku似乎运行正常。但是，当我运行我的rake任务时，我收到以下错误消息： Don't know how to build task 'import_foursquare_response:create_records'

和一个不太有用的堆栈跟踪：

heroku run rake import_foursquare_response:create_records --trace
Your version of git is 2.2.0. Which has serious security vulnerabilities.

我所看到的大多数问题都指出了人们编写实际佣金任务的语法错误，但我无法看到任何问题。

require 'four_square'

namespace :import_foursquare_response do
  include FourSquare

  desc "Load database with results of API calls"
  task :create_records => :environment do
    puts "Loading database..."

非常感谢任何帮助。没有数据让我的应用无用。

我猜这只是因为heroku没有使用rake任务进行任何磁盘写入，请参阅下文：
