在现有的Rails项目上，我在设置环境时遇到了一些困难，这使臭名昭著的“依赖地狱”浮现在脑海。似乎仅限于mini_racer 0.2.4。
这里是怎么回事：

An error occurred while installing mini_racer (0.2.4), and Bundler cannot continue.
Make sure that `gem install mini_racer -v '0.2.4' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
mini_racer
浏览网页，很容易找到导致mini-racer failing to compile · Issue #4 · jules2689/extended_bundler-errors的Add mini_racer handling。由此，我尝试了gem uninstall libv8 && gem install mini_racer -v '0.2.4' --source 'https://rubygems.org/，但无法像上面那样编译。
现在，运行bundle update && bundle install就像是一种魅力，所以我想我现在就可以继续使用它，与团队的其他成员一起看看是否可以更新至少迷你赛车的宝石。然后，我开始完成README.md，以添加一些详细信息，并希望提交到新的分支并要求复审。但是碰巧团队使用过量提交添加了一些git钩子，这些钩子正在崩溃，因为它包括依赖mini_racer-0.2.4的Brakeman：

开发平台摘要：
您将建议采取哪些步骤来解决此依赖性问题？
对于它的价值，我们的团队只是运行了bundle update mini_racer，现在一切正常。当然，它仍然无法在Fedora 31上编译mini_racer 0.2.4。
