Question

尝试将Rails从5.2.0升级到5.2.3的过程比我想象的要困难。在应用程序启动期间，我遇到了Uncaught exception: cannot load such file -- v8。

如果将mini_racer替换为therubyracer，则应用启动，但会抛出ExecJS::RubyRacerRuntime is not supported. Please replace therubyracer with mini_racer in your Gemfile or use Node.js as ExecJS runtime.

我已经安装了nodejs，而我的Gemfile是：

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.3.3'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.2.3'
# Use mysql as the database for Active Record

# gem 'prometheus_exporter'

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
end

group :development do
  gem 'listen', '>= 3.0.5', '< 3.2'
  # Debug on RubyMine
  gem 'debase'
  gem 'ruby-debug-ide', '0.7.0.beta4'
  # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring

  gem 'spring-watcher-listen', '~> 2.0.0'
  # Access an interactive console on exception pages or by calling 'console' anywhere in the code.
  gem 'web-console', '>= 3.3.0'
end

group :development, :test do
  gem 'factory_girl_rails'
  gem 'pry'
  gem 'rspec-rails'
end

group :test do
  gem 'selenium-webdriver'
  # Easy installation and use of chromedriver to run system tests with Chrome
  gem 'chromedriver-helper'
  gem 'database_cleaner'
  gem 'rack-test'
end

是我还是JS运行时环境使它看起来很混乱。人们到处都有大量问题，人们需要正确地组合版本，从而使事情正常进行，而实际上并不知道发生了什么。

任何建议都值得欢迎。谢谢。

这只是尝试：

gem'web-console'，'> = 3.3.0'更改为gem“ web-console”
宝石'spring-watcher-listen'，'〜> 2.0.0'更改为宝石'spring-watcher-listen'
gem“ mini_racer”，平台：：ruby`
