Rails服務器由於uglifier gem失敗

Question

當我嘗試加載Rails服務器時，出現以下錯誤：

/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)

我已經搜索了很多問題，並且我對stackoverflow進行的每個回答都說“ install nodejs”，這已經完成了，但是這並沒有為我解決任何問題。

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

我還已將therubyracer gem添加到我的gemfile中。 我捆綁安裝。 在這本書的最后，因為，老實說，我從任何人那里看到的關於該問題的唯一建議就是安裝nodejs，並且通常基於此標記該線程已解決，因此我無法嘗試其他事情。

使用rvm在ruby 2.4.0上安裝64位Debian 8（jessie）上的rails 4.2.5.1。

編輯：由於似乎沒有人希望對此有所了解，所以這是來自Rails開發人員的更多信息，我知道誰也無法解決問題：

新增中

$stderr.puts e.inspect

在第80行上方，產生：

#<TypeError: wrong argument type Class (expected Module)>

並搜索uglifier，以查看是否在項目中某處引用了某個類，而該類不應在該類中得到：

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（目前），config / application.rb的第7行說

Bundler.require(*Rails.groups)

Answer 1

因此，我對紅寶石表示失望，長話短說。 我使用rvm，因此刪除它非常容易，而且我對該項目也沒有做太多工作。 因此rvm和相關的寶石消失了。 我重新安裝了rvm，但是這次也使用了安裝Rails的選項：

https://rvm.io/rvm/install

\curl -sSL https://get.rvm.io | bash -s stable --rails

這使我開始工作。 所以我想我最好的建議是在使用rvm時使用rails標志。
