Question

我已经为Heroky部署了一个分支，现在我想运行迁移或加载架构，无论哪种方式：

Unable to resolve dependency: user requested 'fileutils (= 1.0.2)' (Gem::UnsatisfiableDependencyError)

我尝试重新启动heroku（heroku restart），然后运行heroku run rake db:schema:load，但没有任何反应。

我也尝试运行gem update --default，但没有任何改变。

我正在运行Rails 5.2，Ruby 2.5.3，Heroku Cedar-14 Stack（已弃用，这可能会引起问题吗？）

有什么想法吗？

Answer 1

将Bunlder升级到v1.9.9后出现此错误，并使用以下命令解决了该问题：

sudo gem install bundler -v 1.17.3

如果安装了多个捆绑软件版本，则可以通过以下方式运行捆绑软件的特定版本：bundle _1.17.3_ exec rspec

尽管似乎以后的捆绑器版本都是错误的，但使用一个旧的捆绑器可能效果最好，至少这是我在Ubuntu上拥有的。

Answer 2

如果在已弃用的堆栈上运行，则对其进行升级应该可以解决问题

无法解决依赖性：用户请求了'fileutils（= 1.0.2）'（Gem :: UnsatisfiableDependencyError）
