带Rails的webpack-dev-server返回400错误

Him*_*ack 1 ruby-on-rails webpack

我的机器上有多个使用Rails和webpacker的项目。一个人开始为我做以下事情:运行webpack-dev-server和rails server,一切都编译了,但是当尝试访问/packs/xxxx.js或.css时,出现400错误(错误请求)->没有错误显示在控制台中。

这是我的webpacker.yml

嘿,我也遇到了这个错误,经过几次调查后,我发现Cookie出了点问题...

我知道这听起来很傻,但是如果您仍然遇到此问题,建议您尝试使用其他Chrome会话或其他浏览器。

如果这可以解决问题,那么只需清除cookie,就可以了。

希望这对其他人有帮助。

注意:这个问题不仅发生在Rails内部,我参与的所有其他项目webpack-dev-server都被破坏了。
