通过 cloud9 上的 heroku 部署应用程序时出现问题，gem 错误

Question

所以我正在尝试部署我的第一个应用程序，但遇到了一些麻烦，看起来我不断收到以下警告，即“Bundler 的运行版本比创建锁定文件的版本旧”。关于如何将更新的 Gemfile.lock 替换为版本控制的任何想法。以下是完整的错误：

Answer 1

首先使用

确保您的捆绑器是最新的

`gem install bundler'

接下来再次运行您的捆绑安装并确保它完成。此问题的主要原因是 gem 文件和锁定文件不匹配。捆绑器是更新锁定文件的工具。

Answer 2

警告消息说您需要运行 gem install bundler 才能获取最新版本的捆绑程序。一旦你这样做了bundle install，这将更新你的 Gemfile.lock，它应该被推送到你的存储库。我会推荐阅读这个SO post 以了解更多关于 Gemfile 和 Gemfile.lock 的信息

Answer 3

您可以解决您的错误，并且可以在更新您的捆绑包后将您的应用程序上传到 heroku。要安装和更新捆绑包，请使用以下命令。

$ bundle install 

$ bundle update

这是您每次对 gem 文件进行任何更改时都必须遵循的常规过程，以使您的应用程序能够了解您在 gem 文件中所做的新编​​辑。

Answer 4

没关系，终于发现我的错误了，这很简单。我正确安装并更新了所有内容，但由于我在 cloud 9 ide 上执行此操作，因此我不得不 git add、git commit 和 git push 我的更改，只要我活着，我就永远不会再忘记这一点。感谢大家的帮助。
