$ rails server
=> Booting Puma
=> Rails 6.1.4 application starting in development
=> Run `bin/rails server --help` for more startup options

我尝试了建议的 rails webpacker:install 命令，它给了我这个
$ rails webpacker:install

我检查了节点的环境变量及其在用户上的所有变量：
和系统级别：
我也试过：

只是以防万一，但它们都没有影响 rails 服务器的结果，我仍然收到相同的错误消息。
我检查了我的纱线和节点版本：
$ node -v
v14.16.0
$ yarn -v
1.22.5
我是 ruby on rails 的新手，我有一个 Windows 10 操作系统，我知道运行 ruby 更困难，但不幸的是，这就是我现在的情况。我也不像我以前对 npm 那样熟悉纱线。任何指导将不胜感激。
