Rails 6本地服务器引导：RAILS_ENV =开发环境未定义

Question

我刚刚创建了一个新的Rails 6应用程序。一切正常，直到我尝试使用启动本地服务器rails s，并收到以下错误消息：

RAILS_ENV=development environment is not defined in config/webpacker.yml, falling back to production environment
Exiting

和

Webpacker configuration file not found /Users/remy/dev/voter/config/webpacker.yml. Please run rails webpacker:install Error: No such file or directory @ rb_sysopen - /Users/remy/dev/voter/config/webpacker.yml (RuntimeError)

但是当我跑步时，rails webpacker:install我仍然有错误。

Answer 1

该错误通常暗示未满足的Yarn依赖关系。在运行之前，尝试安装或更新Yarn rails webpacker:install。

以下是纱线文档，以防万一。
