我知道Github上有很多这些问题（我已经查看了所有这些问题），但没有一个答案对我有用。
当我尝试“git push heroku master”时，我收到错误“找不到任何来源中的libv8-3.15.11.1”。我在我的Gemfile中指定了libv8的版本（使用gem“libv8”，“〜＆gt; 3.11.8.13”），我认为这反映在我的Gemfile.lock（“libv8（3.11.8.13）”）中。我不明白为什么当我指定3.11.8.13时它正在寻找版本3.15.11.1。
我确保我对Gemfiles的所有更改都已提交（当我执行“git status”时，我“无需提交（工作目录清理）。”
我也尝试删除heroku并重新添加（使用“git remote rm heroku”然后“git push heroku master”）。
的Gemfile：

根据这个页面：
https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar
“therubyracer 如果您以前使用的是therubyracer或therubyracer-heroku，那么这些宝石就不再需要了，并且强烈建议不要使用这些宝石。“
因此我从测试应用程序中删除了这些内容。然后我通过ubuntu本地机器安装了node.js，并且在heroku上运行正常。
