Question

我是RailsTutorial.org程序之后的新手，已经安装/设置rvm，ruby 1.9.2，rails，curl，git并创建了我的第一个应用程序并将其推送到github（所以SSH密钥很好）。

下一步是部署到Heroku，这让我感到害怕：

gem install Heroku

工作正常，但在“heroku keys：add”或“heroku create”后出现此错误：

    [app_first (master)]$ heroku keys:add
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- readline (LoadError)
 from <internal:lib/rubygems/custom_require>:29:in `require'

 from /home/john/.rvm/gems/ruby-1.9.2-p0@rails3tutorial/bin/heroku:19:in `<main>

我的猜测是与缺失或错位的宝石有关，但我是一个新秀，所以猜测可能会有所不同。这是宝石环境：

[app_first (master)]$ gem environment

Answer 1

知道了！或者更确切地说，一个伙伴得到了它。这是一个link to the solution。

Answer 2

嘿..我用rvm，ruby 1.9.2和sqlite3完成了安装过程。你放弃了最后一步:)：）

好吧我的解决方案......在与heroku摔跤2天后，这对我有用。）

sudo apt-get install libreadline-dev

cd ~/.rvm/src/ruby-1.8.7-p249/ext/readline

然后构建扩展

ruby extconf.rb && make  && make install

Answer 3

gem install rb-readline

为我解决了。

Answer 4

感谢百忧解！我在Ubuntu 11.10上完成了多用户安装RVM 以下对我有用，使用ruby 1.9.2：

sudo apt-get install libreadline-dev

cd /usr/local/rvm/src/ruby-1.9.2-p290/ext/readline/

ruby extconf.rb && make && make install

Answer 5

herkou文档非常棒。这些是您在heroku docs

上需要的说明

Answer 6

从ruby-1.9.2-p180升级到ruby-1.9.2-p290为我做了

如何让Heroku在Ubuntu 10.10上工作（在Windows机器上使用VirtualBox）？
