“rake assets：precompile”给出了punc错误
我试图预编译我的资产生产，但铁轨似乎没有合作。

在js-assets中find问题的更普遍的方法是：运行rails console并：
JS_PATH = "app/assets/javascripts/**/*.js"; Dir[JS_PATH].each do |file_name| puts "\n#{file_name}" puts Uglifier.compile(File.read(file_name)) end
我有这个相同的问题。 在浏览器中打开您的Javascript控制台，看看哪里出错。 我怀疑（因为这是我的问题的解决scheme），你的一个JS文件有一个错误，它很可能是你写的使用“>”符号的任何JS。
祝你好运错误狩猎。
在我的情况下，我在js文件中使用es6语法()=>{...} 。 用function(){...}replace它function(){...}解决了这个问题。
这太可怕了， 我的本地计算机上没有javascript错误意味着资产编译有问题。
这是我如何解决它。
正如在类似问题的注释中提到的， ExecJS :: ProgramError：运行rake资产时意外的令牌punc«：»，预计punc«：»在生产预编译时 ，我删除了uglifier（在production.rb ，注释掉了压缩器行）和我一起压缩（我曾尝试用其他压缩机，yui没有提供太多的信息，closures似乎给了我一个提示，但没有多大帮助）
然后我在当地压缩资产，然后我推到生产。 （要在本地压缩，使用RAILS_ENV=production rake assets:precompile ）
我跑在服务器上，这是当javascript错误浮出水面。 这基本上是错误的合并文件（主要是由于注释掉的东西）。 我摆脱了这些线路，并推回到生产。 一切都成功了。
我带回了uglifier，删除了public/assets/下的预编译资源，并被推回生产。
我希望这可以帮助别人！
只是在这个问题上，我有同样的问题，发生了什么事情，当预编译生产环境中的资产（并推到Heroku）我的JS文件的几个插入与外来字符，沿线…
<<<<<<<<HEAD =========== >>>>>>(random alphanumeric key)
我只是在我的网站目录中运行全球search“<<”，并迅速find受影响的文件并删除这些条款 – 一切正常。
出于某种原因，在heroku上，当我跑上述代码“uglify”在轨道控制台的JavaScript，它不会报告错误的行号！ 这只是UglifyJS的一个ruby包装，你可以在这里在线使用https://skalman.github.io/UglifyJS-online/ 。
所以我只是在这里复制并粘贴了有问题的js文件，并且报告了行号。 好简单。
validation您在应用程序中添加的新JS文件包括插件和其他由Bower或类似的东西添加。
尝试逐个添加find哪个文件有问题。 在我的情况是在anchor-scroll.js 当我改变使用anchor-scroll.min耙运行正常。
改变这个：
//= require anchor-scroll/scroll
对于：
//= require anchor-scroll/scroll.min
我的问题是有两个成功的电话。
首先是mqtt onSuccess ：
onSuccess() { console.log("mqtt connected") };
我解决了：
onSuccess: function() { console.log("mqtt connected") };
第二个是Ajax成功。 Linter会告诉你
错误：预期的方法速记
但一切都会正常工作。
“/home/drderp/.rvm/rubies/ruby-1.9.3-p194/bin/ ruby / home /drderp/.rvm/gems/ruby-1.9.3-p194@global/bin/rake assets：precompile：all RAILS_ENV =生产RAILS_GROUPS =资产“
粗体部分（ruby，反斜杠和家庭之间）之间有一个空格。
我不知道这是否是一个错字，但可能是你的问题，因为Rails不喜欢目录名称中的空格。 重命名该文件夹，然后再次运行您的代码。
