Heroku上的NewRelic插件：推送失败，原因是“未初始化常量NewRelic:：Logger:：INFO”`

new relic已经启动并正常工作，但现在推送在资产预编译期间失败。它与“newrelic_plugin”gem有关，因为从我的gem文件中删除该行并重新绑定后，推送工作正常

我已经启用了heroku实验室的“用户环境编译”，不确定它是否相关

这是完整的堆栈跟踪；任何帮助都将不胜感激：

嗨，杰伊，我在New Relic工作，我们很乐意帮忙。如果你写信给我们，我们就能更好地解决你的问题support@newrelic.com. 当你写信给我们时，你能详细说明一下为什么要加入newrelic_插件gem吗？为什么您要将它与newrelic\u rpm结合使用？您应该只需要newrelic\u rpm？包括这个StackOverflow问题的URL也会有帮助。谢谢
