rails EXECJS运行时错误
您好我在Demo #index中获得了一个ExecJS :: RuntimeError
下面是突出显示的第6行，下面是我的完整描述。 有人可以A：指出我正确的方向进行调试，以及调试rails的良好参考。 我是铁杆新手。 我的猜测是我错过了一颗gem（我检查过以确保涡轮在那里）或者在turbolinks中的东西是错误的。 我正在使用Rails 4使用rails安装程序（在更新gems和rails以及bundle install等之后）。
下面也是我的gemfile
第6行突出显示：
true %> 以下是我的完整记录：

之前我遇到过这个问题并通过安装node.js （使用MSI安装程序）解决了这个问题。
希望这可以帮助。
我得到了同样的错误并修复它:)
- 打开Gemfile
- 添加以下行：gem’execjs’gem’therubyracer’
- 保存文件中的更改
- 在终端上执行bundle install
＃有关更多支持的运行时，请参阅https://github.com/sstephenson/execjs#readme
gem’therubyracer’，平台:: ruby *
从Gemfile中删除gem
therubyracer是将V8 Javascript解释器嵌入到Ruby中
要么
你需要安装Node.js
不知道问题中的问题是否与我的完全相同（尽管有相同的痕迹）。 无论如何，这是Windows上execjs运行时错误的一个解决方案：
Rodrigo Argumedo的解决方案
这对我有用。 此问题主要发生在Windows操作系统中。 强制您的咖啡脚本源版本为1.8.0。 不支持更高版本。
将其更改或添加到您的gem文件：
gem 'coffee-script-source', '1.8.0'
然后更新coffee-script-source包
bundle update coffee-script-source
这应该可以解决问题。
我使用Rails 5.2和ruby 2.5时遇到了同样的错误。 在我的情况下，问题是gemBootstrap 4.我使用gem 'bootstrap', '~> 4.1', '>= 4.1.3'我禁用了这个gem，Rails开始工作。 为了解决问题，我将gem 'bootstrap'更改为gem 'bootstrap-sass', '~> 3.3', '>= 3.3.7'
