Javascript Coffee脚本未在资产之后加载：我的ActionCable聊天功能的预编译

我正在RubyonRails（v5.0.0）站点中构建聊天功能。我让它最终运行起来，但我运行了bundle exec rake assets:precompile，以便将其推向生产

我好像再也不能让它工作了！这很愚蠢

问题

看起来这些文件不再加载了，没有一个脚本正在生产或开发中运行。 现在，当你输入一条评论时，你会得到一个错误，当然，这是因为没有咖啡脚本来接管你的请求

# Turn on the cable connection by removing the comments after the require statements

你们还需要别的吗？

看起来整个房间都没装咖啡。

你在服务器上运行过

rake assets:precompile RAILS\u ENV=production

吗？可能是因为

config.public\u file\u server.enabled

中的

config/environments/production.rb

设置为

false

（它可能使用了一个环境变量）。检查此项，如果尚未设置为true，则将其设置为true，然后重试。感谢您的回答，不幸的是，所有建议均无效：(
