"webpack“指挥部未找到

Question

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，一切都很完美，但现在我发现了错误。

error Command "webpack" not found.

每当我执行下列任何一项时：

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

我假设这是纱跑webpack，它是运行在“下盖”的webpack bin命令，因为我得到了完全相同的输出对所有三个命令：

yarn run v1.22.5
error Command "webpack" not found.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

正在运行

bundle info webpacker 
yarn list --pattern @rails/webpacker

这两个版本都显示我安装了beta.6版本的webpacker

我有package.json

我不知道我的生活现在缺少什么安装或配置步骤，特别是因为这是工作的，我不知道发生了什么事来打破它？

欢迎任何建议。

Answer 1

让我感到惊讶的是，下面是关于https://makandracards.com/makandra/432947-how-to-fix-webpack-dev-server-not-found的一个建议：

运行纱线安装-检查文件以修复此错误，

我使用命令提示符重新启动了VirtualBox VM，命令提示符作为管理员执行(在Windows下)，运行该命令，并且解决了webpack和webpack-dev服务器的所有问题。

我希望这能帮到别人。
