Rails：Gem::Ext::BuildError：错误：无法构建 gem 原生扩展

Question

我在尝试克隆存储库并启动并运行时遇到了问题。 当我运行 bundler 时，我遇到以下错误。出于某种原因，它不喜欢gem pg_query。在我看到的错误消息中：error: '__int128' is not supported for this target 但这超出了我的知识范围。我已尝试阅读类似的帖子，但尚未找到可行的解决方案。

An error occurred while installing pg_query (0.11.4), and Bundler cannot continu
Make sure that `gem install pg_query -v '0.11.4'` succeeds before bundling.

我尝试运行gem install pg_query -v '0.11.4' 并得到相同的结果。

您好，问题出在您的捆绑程序版本上。您的 GemFile 指定较低的捆绑器版本，但您的系统具有较高的捆绑器版本。 请将正确的捆绑器版本与您的 Gemfile.lock 匹配并安装旧版本的捆绑器。试试下面的代码

gem install bundler -v '~> 1.15'
bundle _1.15_ install
