【问题描述】:
尝试将 Rails 从 5.2.0 升级到 5.2.3 比我想象的要难。我在应用程序启动期间面临Uncaught exception: cannot load such file -- v8。
如果将mini_racer 替换为therubyracer,应用程序会启动,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.
我安装了nodejs,我的Gemfile 如下:
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'

end

end

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

gem 'database_cleaner'
gem 'rack-test'
end
是我还是 JS 运行时环境看起来真的很乱。到处都有很多问题,人们在不知道发生了什么的情况下获得了正确的版本组合,使事情正常进行。
欢迎提出任何建议。谢谢。
【问题讨论】:

明确地说,您是说应用程序加载正常;那么您更改的only (???) 是升级rails,然后出现上述错误?我问是因为如果您无意中升级了其他十几个东西,我们可能很难帮助诊断问题。你能不能显示一个 minimal
Gemfile.lockdiff 来引入错误?
