当我尝试加载rails服务器时，出现此错误：

我已经搜索了很多这个问题，并且每个关于stackoverflow的答案都是间谍说＆＃34;安装nodejs＆＃34;，我已经完成了，这对我来说没有任何修复。
jared@machine:~$ nodejs -v
v0.10.29
jared@machine:~$ node -v
v4.4.4
jared@machine:~$ npm --version
2.15.1
jared@machine:~$ echo $PATH
/home/jared/.rvm/gems/ruby-head/bin:/home/jared/.rvm/gems/ruby-head@global/bin:/home/jared/.rvm/rubies/ruby-head/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/home/jared/.rvm/bin:/home/jared/.rvm/bin:/home/jared/.rvm/bin:/usr/local/nodejs/bin
我还在我的gemfile中添加了therubyracer gem。我捆绑安装。在我的绳子的尽头，因为，老实说，我从任何人看到的关于这个问题的唯一建议是安装nodejs，并且通常线程被标记为基于此解决，我不能再尝试。
在debian 8（jessie）64位上运行rails 4.2.5.1，使用rvm，ruby 2.4.0安装。
编辑：因为似乎没有人想要解决这个问题，这里有一些来自我知道谁也无法解决问题的rails dev的信息：
添加
$stderr.puts e.inspect
在第80行以上产生：
#<TypeError: wrong argument type Class (expected Module)>
搜索uglifier以查看某个类是否在项目的某个地方被引用，它不应该导致：
jared@machine:~/thirteenthagecharbuilder$ grep -r uglifier /home/jared/thirteenthagecharbuilder/
/home/jared/thirteenthagecharbuilder/Gemfile.lock: uglifier (3.0.0)
/home/jared/thirteenthagecharbuilder/Gemfile.lock: uglifier (>= 2.7.1)
/home/jared/thirteenthagecharbuilder/Gemfile:gem 'uglifier', '>= 2.7.1'
/home/jared/thirteenthagecharbuilder/config/environments/production.rb: config.assets.js_compressor = :uglifier
最后（现在），config / application.rb的第7行说
Bundler.require(*Rails.groups)
答案 0 :(得分：0)
所以，我用红宝石长话短说。我使用rvm，所以删除它非常容易，而且我还没有在项目上完成很多工作。所以rvm和相关的宝石消失了。我重新安装了rvm，但这次也使用了安装rails的选项：
\curl -sSL https://get.rvm.io | bash -s stable --rails
这让我起来了。所以我想我最好的建议是在使用rvm时使用rails标志。
