ExecJS :: ProgramError：意外的令牌：名称（选项）
我的应用在本地环境中运行良好。 我试图git push构建git push送到heroku。 我的命令是：
bundle install git add . git commit -am "abcdef" git push heroku master
然后我遇到了资产问题：预编译

请注意，我有编译器特定的资产编译（见下文）。 我想知道这是否会导致这个问题。
视图/布局/ application.html.erb
"all", 'data-turbolinks-track' => true %> true %>
初始化/ assets.rb
# Compile controller assets %w( recruiters events forms candidates ).each do |controller| Rails.application.config.assets.precompile += ["#{controller}.js", "#{controller}.css"] end
有什么想法或建议吗？
更新我能够找到问题的来源。 虽然我不确定什么是错的，为什么它在当地工作正常。
238 if (fieldClass.match(/(select|checkbox-group|radio-group)/)) { 239 previewData.values = []; 240 241 $('.sortable-options li', field).each(function() { 242 let option = {}; ==============^ SyntaxError: missing ; before statement 243 option.selected = $('.select-option', $(this)).is(':checked'); 244 option.value = $('.option-value', $(this)).val(); 245 option.label = $('.option-label', $(this)).val(); 246 247 previewData.values.push(option); 248 }); 249 }
语法错误
通过更新js语法，我能够解决问题并且资产预编译成功完成。
原版的
let option = {};
更新
var option = {};
