Question

我从 Rubymine 运行 Rails 时遇到问题，因为它无法加载下面的堆栈中的 uglifier gem。请注意， Node.js 已安装在我的 Windows 7 计算机上。

从 cmd.exe ，“rails s”运行良好：Web应用程序启动。

从 RubyMine 运行按钮，默认配置，我收到错误：

>rails --version
Rails 4.2.6
>node --version
v0.10.22
>ruby --version
ruby 2.2.4p230 (2015-12-16 revision 53155) [i386-mingw32]

我从 RubyMine 终端收到同样的错误。

以下是我的环境的一些信息（来自 cmd.exe 和 RubyMine 的相同输出）：

source 'https://rubygems.org'


gem 'rails', '4.2.6'
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'

gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc

gem 'bcrypt', '~> 3.1.7'

group :development, :test do
  gem 'byebug'
end

group :development do
  gem 'web-console', '~> 2.0'
end

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

Ruby 是使用 Windows 7 计算机上的 Rails Installer 安装的。使用官方安装程序也安装了 Node.js 。 RubyMine 8.0.4 （最终，不确定是否还有社区版）

我怀疑 RubyMine 中存在环境问题，其中 rails / bundler / gem /？无法“看到” Node.js ，其中 cmd.exe 可以。

我认为当我尝试启动 RubyMine 调试模式时错误已经开始。

有关如何解决问题的想法吗？

Answer 1

我遇到了同样的问题，虽然我的解决方案并不那么简单！

我有一个运行配置，其中“环境变量”字段设置为PATH=d:\opt\curl-7.40.0-devel-mingw64\bin\;%PATH%;=。但是，当我点击此字段右侧的“...”时，在值列中显示d:\opt\curl-7.40.0-devel-mingw64\bin\;%PATH%" (without the "=" at the end)。

我对其进行了更改，使其包含node.exe

的路径

PATH=d:\opt\curl-7.40.0-devel-mingw64\bin\;d:\opt\nodejs\;%PATH%;

现在工作正常。

我在Windows 10计算机上使用Rails 4.2.5运行ruby 2.2.3-x64。

Answer 2

检查您的Gemfile是否具有以下gem

gem 'uglifier'

如果你已经在Gemfile中拥有了gem，那么运行bundle install并检查是否安装了uglifier gem。

Answer 3

我终于得到了它的工作，如果其他人有同样的问题，这里是上下文和解决方案。

我已经定义了一个用户范围的 Path 变量，该变量引用了我的系统 Path ：

%Path%;C:\tools\…

在RedMine中，此%Path%不再被解释（不知道为什么）。我通过输入 RubyMine 终端来看到它：

echo %Path%

结果显示“%Path%”，而非内容。

我只需重新启动计算机即可解决问题。

在Rubymine中，Rails无法加载'uglifier'宝石
