Rails 服务器因丑化 gem 而失败
Rails server fails because of uglifier gem
当我尝试加载 rails 服务器时，出现此错误：
/home/jared/.rvm/gems/ruby-head/gems/bundler-1.11.2/lib/bundler/runtime.rb:80:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'uglifier'. (Bundler::GemRequireError)

我搜索了很多这个问题，我在 Whosebug 上发现的每个答案都说 "install nodejs"，我已经这样做了，但这并没有为我解决任何问题。
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
我还添加了 rubyracer gem 到我的 gem 文件中。我捆绑安装。在我的绳子的尽头，因为，老实说，我从任何人那里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，我无法尝试更多的事情。
运行 rails debian 8 (jessie) 64 位上的 4.2.5.1，使用 rvm，已安装 ruby 2.4.0。
编辑：由于似乎没有人想解决这个问题，这里有一些来自 rails 开发人员的更多信息，我知道谁也无法解决问题：
添加
$stderr.puts e.inspect
在第 80 行的正上方产生：
#<TypeError: wrong argument type Class (expected Module)>
然后搜索 uglifier 以查看 class 是否在项目中不应被引用的某处导致：
jared@machine:~/thirteenthagecharbuilder$ 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)
所以，我核爆了 ruby，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太多工作。所以 rvm 和相关的宝石不见了。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
这让我振作起来 运行。所以我想我最好的建议是在使用 rvm 时使用 rails 标志。
