Rails webpacker出于某种原因总是认为NODE_ENV是生产的,尽管我使用`webpack-dev-server`并将NODE_ENV设置为开发

Question

作为标题,我使用的是docker ruby​​ 2.3.5(ubuntu)环境,尽管我已经设置了NODE_ENV =开发,当我试图拦截process.env.NODE_ENV我仍然看到生产的值时,我无法找到它已被覆盖的任何地方.它只发生在docker环境中但不在我的MacOS上,不确定是什么原因？

更新:这里是Dockerfile和docker-compose.yml供参考:https://gist.github.com/goodwill/b4e677ccf8fe0079183adeec35218812

更新:这是我在运行webpacker-dev-server时遇到的错误:

Docker 容器不会从本地环境收集环境变量。

在 Dockerfile 中设置环境变量。例如：

ENV NODE_ENV=development

或者，您可以从命令行使用该环境变量运行容器：

$ docker run -e NODE_ENV=devlopment mycontainer
