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

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 yarn add @rails/webpacker 解决了这个问题，返回错误 Expected version "^6 || ^7 || ^8 || ^9 || ^10 || ^11 || ^12 || >=13.7". Got "13.6.0"要解决这个问题:

将节点更新到适当的版本(参见上面的错误)

删除 node_modules目录

使用 yarn install --check-files 更新 yarn 文件

使用 rails webpacker:install 安装 webpacker

通过 bin/webpack-dev-server 确认它有效并且没有错误
