在Rubymine中，Rails无法加载“uglifier”宝石。

Question

我在Rubymine运行Rails时遇到了一个问题，在这里，它无法用下面的堆栈加载uglifier gem。请注意，Node.js安装在我的Windows 7计算机上。

在cmd.exe中，“rails”运行良好: web应用程序启动。

在默认配置的RubyMine运行按钮中，我得到了错误：

我从RubyMine终端得到了同样的错误。

下面是有关我的环境的一些信息(来自cmd.exe和RubyMine的相同输出)：

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

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

我怀疑RubyMine内部存在一个环境问题，其中rails/bundler/gem/？不能“看到”Node.js，在cmd.exe可以的地方。

我认为当我尝试启动RubyMine调试模式时，错误就开始了。

对如何解决这个问题有什么想法吗？

谢谢

Answer 1

我终于让它发挥作用了，这是上下文和解决方案，如果其他人有同样的问题。

我定义了一个用户作用域路径变量，该变量引用我的系统路径为：

%Path%;C:\tools\…

在RedMine中，这个%Path%不再被解释(不知道为什么)，. I通过在RubyMine终端中输入来看到它：

echo %Path%

结果显示的是"%Path%"，而不是其内容。

我通过简单的重新启动来解决这个问题。

Answer 2

我也遇到了同样的问题，尽管我的解决方案并不那么简单！

我有一个运行配置，在PATH=d:\opt\curl-7.40.0-devel-mingw64\bin\;%PATH%;=中设置了“环境变量”字段。但当我点击“.”就在这个字段中，在value列中写着d:\opt\curl-7.40.0-devel-mingw64\bin\;%PATH%" (without the "=" at the end)。

我更改了它，以便它包含到node.exe的路径

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

现在它很好用。

我在Windows 10机器上使用Rails 4.2.5运行ruby2.2.3-x64。

检查您的Gemfile是否有以下gem

gem 'uglifier'

如果Gemfile中已经有了gem，那么运行bundle install并检查该包在安装uglifier中是否。
