使用sap-Fibers时出现HANA XS高级错误

Question

当我推送我的第一个XS应用时，我得到了错误。

我从Github (myapp1)获取了应用程序，然后添加了节点模块，然后推送了它。

下面是我的错误日志：

你能帮个忙吗？

我不知道怎么才能修好它。

诚挚的问候

Answer 1

您使用的node.js引擎很可能比发布此版本的sap-xsjs的目的更高。这会导致sap-fibers等依赖本机模块失败，因为在收缩包装模块中找不到用于较新节点API版本的本机二进制文件。

尝试通过应用程序package.json中的engines字段强制使用较低的node.js引擎(0.12.x或4.x)，或者尝试将sap-xsjs升级到支持node.js 6.9的更新版本

最好的
