我已经为带有的Rails 6.1项目安装了webpack
yarn add webpack
yarn add -D webpack-cli
yarn add @rails/webpacker@6.0.0-beta.6
bin/rails webpacker:install
直到最近，一切都很顺利，但现在我得到了错误
error Command "webpack" not found.
每当我执行以下任何操作时：
./bin/webpack
./bin/webpack-dev-server
yarn run webpack
我假设它是纱线运行的webpack；在封面下"；通过webpack-bin命令，因为我得到了所有3个命令完全相同的输出：
yarn run v1.22.5
error Command "webpack" not found.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
运行
bundle info webpacker
yarn list --pattern @rails/webpacker
两者都显示我已经安装了测试版6的webpacker
我有包.json

我一辈子都想不出现在缺少了什么安装或配置步骤，尤其是在这个过程中，我不确定是什么破坏了它？
欢迎提出任何建议。

运行yarn install--检查文件以修复此错误，

我希望这能帮助到别人。
