如何解决 mini_racer 0.2.4 编译问题以解决对 Fedora 31 的 Bundler 依赖？

Question

登陆一个现有的 Rails 项目，我在设置环境时遇到了一些困难，这让我脑海中冒出了臭名昭著的“依赖地狱”。不过，它似乎仅限于 mini_racer 0.2.4。

事情是这样的：

bundle install
# […] lot of working stuffs

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mini-racer failing to compile · Issue #4 · jules2689/extended_bundler-errors 到Add mini_racer handling。从这里我尝试了gem uninstall libv8 && gem install mini_racer -v '0.2.4' --source 'https://rubygems.org/，但它无法像上面那样编译。

现在，运行bundle update && bundle install 就像是一种魅力，所以我想我现在可以继续使用它，并与团队的其他成员一起看看我们是否可以至少更新迷你赛车宝石。然后我开始完成 README.md 以添加一些细节，并想在新分支中提交并要求审查。但碰巧团队使用 overcommit 添加了一些崩溃的 git 钩子，因为它包括依赖于 mini_racer-0.2.4 的 Brakeman：

您建议采取哪些步骤来解决此依赖问题？

不管怎样，我们的团队只运行了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。
