当我在开发环境中运行我的 Rails 6.0 应用程序时，我会在 development.log 上获得下一个跟踪

我正在使用 webpacker 4.0.7、rails 6.0.0 和 ruby​​ 2.6.5

我想知道为什么会出现此错误以及如何解决。

谢谢

解决方案

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（参见上面的错误）
  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. 确认它正常工作bin/webpack-dev-server并且没有错误
