我是一名编码训练营开发人员，一直在努力在Web应用程序中实现身份验证。我制作过使用API调用的应用程序，但一直在学习和实践其他编码概念。我发现我可以将React项目放入Rails项目中，并将一个完整的堆栈项目部署到Heroku。这有助于我解决使用会话和令牌进行安全API调用的问题。我即将开始在Heroku上非本地配置项目，并尝试再次实现用于身份验证的会话和cookie组合。

我似乎在尝试创建React客户端的生产构建的项目和运行部署以将es20client/build的内容复制到public/的npm之间遇到了错误
Build Failed之前的最后几行是"cp："es20client/build/. public/"后面缺少目标文件操作数""有关详细信息，请尝试" cp--help "。"
并运行：cp-帮助
退货：
cp：非法选项---用法：cp [-R [-H|- L|- P]][-fi|- n][-aclpsvXx]源文件目标文件cp [-R [-H|- L|- P]][-fi|- n][-aclpsvXx]源文件...目标目录
附上一些文件。
