找不到命令“webpack”

如何解决找不到命令“webpack”

我已经为我的 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

直到最近一切都运行良好，但现在出现错误

error Command "webpack" not found.

每当我执行以下任何一项时：

./bin/webpack
./bin/webpack-dev-server
yarn run webpack

我假设它是由 webpack bin 命令“在幕后”运行的 yarn run webpack，因为我得到的所有 3 个命令的输出完全相同：

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

两者都显示我安装了 webpacker 的 beta.6 版本

我有 package.json

# package.json

  "name": "ancestors","private": true,"dependencies": {

}

和 webpacker.yml

我终生无法弄清楚现在缺少什么安装或配置步骤，尤其是因为它正在运行，我不确定发生了什么破坏它？

欢迎提出任何建议。

解决方法

令我惊讶的是，按照 https://makandracards.com/makandra/432947-how-to-fix-webpack-dev-server-not-found 上的建议

运行 yarn install --check-files 来修复这个错误，

我从以管理员身份（在 Windows 下）执行的命令提示符下使用 vagrant 重新启动了 VirtualBox VM，运行了命令，我在 webpack 和 webpack-dev-server 上遇到的所有问题都解决了。

我希望这对某人有所帮助。
