我Gemfile.lock是版本控制。

Answer 1

你說你的Gemfile.lock是版本控制，但是你的錯誤信息是說Gemfile.lock與你的Gemfile不匹配。

您需要在本地bundle install並提交修改後的Gemfile.lock。

Answer 2

發生了什麼事情，你已經改變了你的Gemfile，但你沒有使用Bundler在本地更新你的寶石。這意味着您的Gemfile文件和Gemfile.lock文件不同步。

爲了解決這個問題，請運行bundle install，提交您的更改並再次推送到Heroku。這將安裝您添加的postmark-rails寶石，更新Gemfile.lock並使所有內容重新同步。

什麼可能會困惑你使用gem install安裝寶石不會更新Bundler知道的寶石。 Bundler的工作是管理項目的寶石，所以每當你添加一個新的寶石時，一定要運行Bundler來更新東西。
