无法通过Bundler安装宝石（推送到Heroku）

Question

我在将Rails 4项目推到GIT时遇到问题：

johann@johann-R430-P430-R480:~/projects/spread$ git push heroku master
Fetching repository, done.

该应用程序可以完美地在localhost上运行，包括tomz-libsvm-ruby-swig-0.3.3。这可能是什么问题？ ：[ 提前致谢！

Answer 1

修改您的Gemfile以添加替代源...

所以代替...

source 'https://rubygems.org'

你应该有...

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

然后Heroku应该可以找到宝石。
