我知道 Github 上有很多这样的问题（我已经浏览了所有这些问题），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“在任何来源中都找不到 libv8-3.15.11.1”。我在我的 Gemfile 中指定了 libv8 的版本（使用 gem "libv8", "~> 3.11.8.13"），我认为这反映在我的 Gemfile.lock ("libv8 (3.11.8.13)") 中。当我指定 3.11.8.13 时，我不明白为什么它在寻找版本 3.15.11.1。
我确保我对 Gemfile 的所有更改都已提交（当我执行“git status”时，我得到“没有提交（工作目录干净）”。
我还尝试删除 heroku 并重新添加它（使用“git remote rm heroku”，然后使用“git push heroku master”）。
