Rails 3.1部署到Heroku错误

本文介绍了Rails 3.1部署到Heroku错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试将我的应用程序部署到Heroku，之前我已经在Windows机器上完成了，现在我正在使用mac。

I'm trying to deploy my app to Heroku, I've done this before on my Windows machine, and now I am currently using a mac.

我我第一次尝试使用Postgresql。

I'm trying to use Postgresql for the first time.

我的Gemfile中有以下内容：

I have the following in my Gemfile:

gem 'pg'

编辑：

AndrewDavis-OSX:lunchbox ardavis$ rvm list rvm rubies => ruby-1.9.2-p180 [ x86_64 ] AndrewDavis-OSX:lunchbox ardavis$ heroku rake db:migrate rake aborted! /app/config/initializers/session_store.rb:3: syntax error, unexpected ':', expecting $end App::Application.config.session_store :cookie_store, key: '_app_session' ^ (See full trace by running task with --trace) (in /app)

如你所见，我正在运行ruby 1.9.2。而且我的英雄迁移有错误。

As you can see, I am running ruby 1.9.2. And there is the error for my heroku migration.

编辑2：

刚刚创建了一个全新的rails应用程序使用Rails 3.1.rc1。我设置gemfile包含

Just created a brand new rails app using Rails 3.1.rc1. I set the gemfile to include

group：production do gem'therubyracer-heroku'，'0.8.1.pre3' gem'pg ' end

group :production do gem 'therubyracer-heroku', '0.8.1.pre3' gem 'pg' end

我做了一个快速的git init，提交，然后'heroku创建'和'git push heroku master'。那些都工作很好。但是问题是当我尝试'heroku rake db：migrate'时。我收到与上面相同的错误。

I did a quick git init, commited, then 'heroku create' and 'git push heroku master'. Those all work just fine. However the problem is when I try 'heroku rake db:migrate'. I get the same error that you see above.

TEMP FIX EDIT：

TEMP FIX

所以...如果我更改我的配置/ initializers / session_store.rb从

So... if I change my config/initializers/session_store.rb from

App::Application.config.session_store :cookie_store, key: '_app_session'

至

App::Application.config.session_store :cookie_store, :key => '_app_session'

并从

ActionController::Base.wrap_parameters format: [:json]

to

ActionController::Base.wrap_parameters :format => [:json]

然后我可以做'heroku rake db：migrate'就好了。任何人都在意解释为什么这样做是以原始方式在本地工作的，没有任何修改冒号/散列？原来的方式是从'rails new myApp'中生成的默认值

Then I'm able to do 'heroku rake db:migrate' just fine. Anyone care to explain why this works locally the original way, without any modification of the colons/hashes? The original way is the generated default from doing 'rails new myApp'

推荐答案

需要迁移Heroku堆栈，可以运行这个命令这样做：

The Heroku stack needs to be migrated, you can run this command to do so:

heroku stack:migrate bamboo-mri-1.9.2

我在本地运行1.9.2，这就是为什么它在本地工作。但是在Heroku，它运行的是1.8.7。

I was running 1.9.2 locally, which is why it was working locally. But on Heroku, it was running 1.8.7.
