Ruby on rails 无法通过Bundler安装gems（推送到Heroku）

将Rails 4项目推到GIT时遇到问题：

johann@johann-R430-P430-R480:~/projects/spread$ git push heroku master

该应用程序在本地主机上运行得非常好，包括tomz-libsvm-ruby-swig-0.3.3 有什么不对劲吗[

提前感谢！

修改您的GEM文件以添加替代源

所以不是

source 'https://rubygems.org'

你应该

source 'https://rubygems.org'
source 'http://gems.github.com'

然后Heroku就可以找到宝石了。

我很惊讶……我从宝石网站上得到了这个建议……它清楚地表明你需要添加作为来源。你（在日志中）是吗看到从两个gem站点提取gem元数据了吗？

gem'tomz libsvm ruby swig'，'0.3.3'，：git=>'https://github.com/purchease/libsvm-ruby-swig.git“

这可能行得通吗？你说得对，我只是忘了在提交中重新添加修改过的GEM文件。谢谢！太好了！：）如果你对我的答案满意，请接受它。：）
