ruby-on-rails - Rails : bootsnap. dlopen : no suitable image found. 找到了:(LoadError)

Question

我是 ruby​​-on-rails 和 mac 的新手。我收到此错误 dlopen(/Users/hasnainsomro/.rvm/gems/ruby-2.6.3/gems/eventmachine-1.2.7/lib/rubyeventmachine.bundle, 9): no suitable image found. Did find: (LoadError) .由 bootsnap 引起。

我正在尝试编译一个 ruby​​-on-rails 项目。使用
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-darwin18]Rails 5.2.3Bundler version 2.0.2xcode-select version 2354macOS Mojave version 10.14.6
到目前为止，它一直运行得很完美。我已经搜索并尝试了很多东西，但没有找到合适的解决方案。

这是我的回溯日志:

Answer 1

我通过谷歌搜索，发现我正在使用 eventmachine gem 没有指定平台。我必须安装 eventmachine带有指定平台的 gem。

Although eventmachine is provided as x64-mingw platform gem, it doesn't support ruby-2.4 or 2.5 right now. Use gem install eventmachine --platform ruby in the meantime.
