环境：

• windows 10 x64
• Ruby：Ruby2.7.2p137（2020年10月1日修订版本5445e04352）[x64-mingw32]
• 节点：版本16.13.1
• 国家预防机制：8.1.2

问题陈述：

在Windows 10 x64中运行Rails项目内的Webpack脚本无法正常工作。
似乎必须在exec for Windows之前设置环境

异常：

工头开始向下投掷错误

$ foreman start

但是，在单独的终端上执行bin/webpack-dev-server可以正确编译。

$ bin/webpack-dev-server

我尝试从Gemfile中删除foreman，然后通过following answer使用gem命令重新安装
Gemfile

group :development do
  # gem "foreman", require: false
end

$ gem uninstall foreman
$ gem install foreman

gem uninstall foreman正在从ruby主目录本身中删除foreman。

编辑3：

我尝试了bundle exec rails webpacker:install，但foreman start再次抛出相同的错误。而bin/webpack-dev-server在端口上正确编译为config/webpack文件。

$ bundle exec rails webpacker:install
