问题描述
按照该教程，我一直在使用Cloud Application Programming Model（Node.js）开发应用程序： https://github.com/SAP-samples/cloud-cap-nodejs-codejam
很不幸，我无法将其部署到Cloud Foundry。我还根据上面的教程创建了应用（书店），以检查是否遇到相同的错误，并且确实如此。
该错误看起来如下，当我尝试从练习10执行npm run build:mta命令时，就会发生该错误。

有人也遇到过这个问题吗？任何帮助将不胜感激。
解决方法
bookshop-srv是否应提供UI所需的内容？在我看来，bookshop-srv应该提供srv-binding（而不是srv-api），反之亦然。
,您用于为项目构建 mta 的命令 - npm run build:mta 在内部使用 SAP Cloud MTA Build Tool，简称为 MBT。 MBT 在内部使用 GNU Make，如指定的 here。尝试按照说明 here 安装 GNU Make，然后使用相同的命令 - npm run build:mta 再次尝试为您的项目构建 mta。它将成功构建。
