【问题标题】：Error: NJS-045: cannot load the oracledb add-on binary for Node.js 10.17.0 (linux, x64)错误：NJS-045：无法为 Node.js 10.17.0（linux、x64）加载 oracledb 附加二进制文件

【问题描述】：

我正在将我的 aws lambda 函数从 8.11 更新到新的节点运行时 10.x。为此，我将现有的 oracle 二进制文件 (node-oracledb 1.13.1) 更新为 (node-oracledb 4.1.0) 并将一个包发布到 npm 注册表中。更新 node-oracledb@4.1.0 后，当 lambda 函数之一尝试将数据插入 oracle db 时，我收到以下错误。

【解决方案1】：

检查您是否确实干净地升级了 node-oracledb。错误消息来自NAN 时代（node-oracledb 4.0 之前），它导致 node-oracledb 二进制文件和 Node.js 版本之间的紧密耦合。这就是为什么您会收到有关 NODE_MODULE_VERSION 不兼容的消息的原因。在 node-oracledb 4 中，实现改为使用 N-API，它允许一个 node-oracledb 二进制文件与多个 Node.js 版本一起使用。
