我已经将JS运行时安装为Node，并且已经捆绑了update-ed和bundle install-ed，但是仍然出现此错误:

I have installed my JS runtime as Node, and I have bundle update-ed and bundle install-ed, but I still get this error:

/Users/macbook/Documents/Studies/Coding/the_back_end/the_odin_project/odin_on_rails/hello_app/config/boot.rb:4:in `require': cannot load such file -- bootsnap/setup (LoadError) from /Users/macbook/Documents/Studies/Coding/the_back_end/the_odin_project/odin_on_rails/hello_app/config/boot.rb:4:in `<top (required)>' from /Users/macbook/Documents/Studies/Coding/the_back_end/the_odin_project/odin_on_rails/hello_app/bin/rails:8:in `require_relative' from /Users/macbook/Documents/Studies/Coding/the_back_end/the_odin_project/odin_on_rails/hello_app/bin/rails:8:in `<top (required)>' from /Users/macbook/.rvm/gems/ruby-2.3.4/gems/spring-2.0.2/lib/spring/client/rails.rb:28:in `load' from /Users/macbook/.rvm/gems/ruby-2.3.4/gems/spring-2.0.2/lib/spring/client/rails.rb:28:in `call' from /Users/macbook/.rvm/gems/ruby-2.3.4/gems/spring-2.0.2/lib/spring/client/command.rb:7:in `call' from /Users/macbook/.rvm/gems/ruby-2.3.4/gems/spring-2.0.2/lib/spring/client.rb:30:in `run' from /Users/macbook/.rvm/gems/ruby-2.3.4/gems/spring-2.0.2/bin/spring:49:in `<top (required)>' from /Users/macbook/.rvm/gems/ruby-2.3.4/gems/spring-2.0.2/lib/spring/binstub.rb:31:in `load' from /Users/macbook/.rvm/gems/ruby-2.3.4/gems/spring-2.0.2/lib/spring/binstub.rb:31:in `<top (required)>' from /Users/macbook/Documents/Studies/Coding/the_back_end/the_odin_project/odin_on_rails/hello_app/bin/spring:15:in `require' from /Users/macbook/Documents/Studies/Coding/the_back_end/the_odin_project/odin_on_rails/hello_app/bin/spring:15:in `<top (required)>' from bin/rails:3:in `load' from bin/rails:3:in `<main>'

这是我的Gemfile中的内容，

Here's what's in my Gemfile ,

source 'rubygems' gem 'rails', '5.1.4' gem 'puma', '3.9.1' gem 'sass-rails', '5.0.6' gem 'uglifier', '3.2.0' gem 'coffee-rails', '4.2.2' gem 'jquery-rails', '4.3.1' gem 'turbolinks', '5.0.1' gem 'jbuilder', '2.7.0' group :development, :test do gem 'sqlite3', '1.3.13' gem 'byebug', '9.0.6', platform: :mri end group :development do gem 'web-console', '3.5.1' gem 'listen', '3.1.5' gem 'spring', '2.0.2' gem 'spring-watcher-listen', '2.0.1' end gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

我对此感到有些迷茫，在任何地方都找不到任何有用的答案.

I feel a little lost on that one, and I can't find any helpful answer anywhere.

非常感谢！

推荐答案

gem bootsnap出现问题，其主要工作是加快Rails的启动时间.

You have an issue with the gem bootsnap which main job is to accelerate rails startup time.

因此，您应该:

• 如果需要bootsnap，请将gem 'bootsnap'添加到gemfile进行安装.
• 如果您不想使用bootsnap，请删除config/boot.rb中的行require 'bootsnap/setup'

• In case you want bootsnap, add gem 'bootsnap' to your gemfile to install it.
• In case you don't want bootsnap, remove the line require 'bootsnap/setup' in config/boot.rb
