标签： ruby-on-rails-4 precompile-assets

我完成了一个网站建设，并希望将其部署到Digital Ocean VPN。安装了Capistrano和乘客。在初始部署期间，我收到的错误显然与预编译资产有关，所以我尝试了＃34; rake assets：precompile --trace RAILS_ENV = production＆＃34;在我的rails生产环境本地，该过程中止此消息：＆＃34; JSON :: GeneratorError：源序列非法/格式错误utf-8＆＃34; 任何人都可以帮助我，我似乎无法解决这个问题。

答案 0 :(得分：3)

我遇到了完全相同的错误消息。有了这个说法，我用Google搜索＆＃34;检查文件是否有效utf-8＆＃34;并找到了isutf8(1): check whether files are valid UTF-8 - Linux man page。所以我安装了isutf8，然后从我的linux机器上的Rails根目录运行以下命令

isutf8 `find app`

虽然输出中有很多噪音，但它告诉我app/assets/javascripts/filterbar.js: line 1, char 1, byte offset 41: invalid UTF-8 code。所以我打开了那个文件。中提琴！我看到一些乱码。删除这些字符后，rake assets:precompile成功了。当然，你的实际有罪文件可能会有所不同。您还可以使用其他实用程序来检查utf-8，例如在this stackoverflow question on utf-8中。
