将Rails应用程序部署到Heroku时出现语法错误:ExecJS :: RuntimeError:SyntaxError:Unexpected character

我正在尝试将我的应用程序部署到Heroku,但它给我这个错误.

"ExecJS :: RuntimeError:SyntaxError:意外字符'''(行:14577,col:33,pos:440811"

我认为coffeescript/javascript有问题.我删除了所有的coffeescript文件,我不知道我做错了什么.

正如Iceman所说,我试过运行命令

rake资产:预编译RAILS_ENV =开发

它说

我的图像文件有问题吗？

正如一些用户所提到的,问题是Rails JS uglifier无法处理ES6模板文字.

Uglifier现在具有支持ES6/ES2015 +语法的Harmony模式.

您可以通过将:harmony => true选项传递给Uglifier 来启用它.

打开 config/environments/production.rb

更换

config.assets.js_compressor = :uglifier

同

config.assets.js_compressor = Uglifier.new(harmony: true)

我面临类似的错误,似乎Rails JS uglifier无法处理ES6模板文字.您可能需要将"`"(模板文字)替换为单引号或双引号.如果你想验证,请复制粘贴你有问题的JS(你必须在你的JS目录中搜索"`")文件https://jscompress.com/并查看错误.
