我也遇到了这个问题。对我来说，问题是节点版本（13.6.0）。我通过运行解决了这个问题yarn add @rails/webpacker，它返回了错误Expected version "^6 || ^7 || ^8 || ^9 || ^10 || ^11 || ^12 || >=13.7". Got "13.6.0"

要解决这个问题：

1. 将节点更新到适当的版本（请参阅上面的错误）
2. 删除node_modules目录
3. 更新纱线文件yarn install --check-files
4. 安装 webpackerrails webpacker:install
5. 确认它有效bin/webpack-dev-server并且没有错误
