Question

首先，这是我的第一个问题。我使用Strack Overflow已有好几年了，我想对每个花费时间询问和回答问题的人表示感谢。你们使我的事业成为可能

我正在尝试在Heroku中部署Rails应用，但在推送分支后却收到此错误： 无法通过Bundler安装gem。 我的gems文件非常简单：

宝石文件：

我已经尝试重建我的Gemfile.lock。我删除了它并运行捆绑更新 + 捆绑安装

这是我第一次来到Heroku，我担心也许我在推一些不兼容的宝石。

关于设置： ruby 2.3.1和 rails 5.2.0

感谢您的帮助！

谢谢。

Answer 1

我发现将您正在运行的当前红宝石版本添加到gem文件中，然后运行

捆绑更新--ruby

做得很好。

heroku上的这篇文章详细介绍了 https://devcenter.heroku.com/articles/ruby-versions

Answer 2

以下是解决该问题的步骤。由于某些原因，您的Gemfile.lock文件未正确提交。

捆绑您的宝石并指定地添加文件，然后提交并推回heroku

bundle
git add -f Gemfile.lock
git commit -m 'added Gemfile.lock'
git push heroku master

[Heroku] [Rails]！无法通过Bundler安装宝石
