Question

我找不到其他人有这个错误，所以我希望这不是我的机器特有的东西。

-----> Heroku receiving push
-----> Sinatra app detected

-----> Installing gem data_mapper 1.0.0 from http://rubygems.org
      ERROR:  Error installing data_mapper:
       dm-migrations requires dm-core (~> 1.0.2, runtime)
!     Heroku push rejected, failed to install gem

error: hooks/pre-receive exited with error code 1
To git@heroku.com:episodes.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:episodes.git'

我正在使用bundler 1.0.7来管理我的依赖项。

这是我的Gemfile：

source :rubygems
gem 'sinatra', '>= 1.0'
gem 'rake'
gem 'rspec', :require => 'spec'
gem 'data_mapper'
gem 'rack-test'
gem 'dm-core'
gem 'dm-sqlite-adapter'
gem 'dm-timestamps'
gem 'dm-validations'
gem 'dm-aggregates'
gem 'dm-migrations'
gem 'haml'

使用Gemfile.lock（最新）

在我的实际应用中，我的要求是按此顺序：

require 'rubygems'
require 'bundler/setup'
require 'dm-core'
require 'dm-validations'
require 'dm-timestamps'
require 'dm-migrations'
require 'dm-types'
require 'haml'
require 'yaml'
require 'json'
require 'ostruct'
require 'sinatra'

有没有什么不同寻常的Heroku会把这个错误抛给我？

Answer 1

问题是您正在使用此存储库：https://github.com/zapnap/sinatra-template

除了Gemfile之外，它还有一个指定Datamapper 1.0.0的.gems文件。摆脱该文件，这应该解决它。

Answer 2

我想，我可能错了，gem'data_mapper'就像是一个元宝石。从列表中删除并尝试

用dm-migrations推送到Heroku的问题
