如何解决Rails 6 上的 Webpacker - assets:precompile 给出了令人困惑的输出并且没有资产？
下面的输出表示错误和成功。尽我所能看到“错误”是由于运行命令“yarn --version”时出现的一些问题，而不是由于其他代码打包问题？
此外，没有包含预编译 javascript 资产的资产文件夹？但它说“成功已经是最新的”？
此外，该应用程序在开发环境中按预期工作。
欢迎任何指点。我知道目前 Sprockets 仍然处理 css 和图像，而 Webpacker 处理 javascript 包。我在 Rails 页面中使用了大量 javascript，它在开发中运行良好，在此应用的先前 Rails 5 版本中运行良好。
c:\railsapps>cd testingapp

成功已经是最新的。

轨道中止！
