}

DLL 文件的运行时路径

为了确保 DLL 文件在运行时被找到，你需要将 DLL 文件放在下列路径之一：

• 可执行文件所在的目录。
• 在系统 PATH 环境变量中添加包含 DLL 文件的路径。
• 将 DLL 文件复制到项目的根目录中。

编译和运行

在项目根目录下运行以下命令：

node-gyp configure node-gyp build

编译完成后，在 Node.js 中加载和运行你的本地模块：

const yourModule = require('./build/Release/native_module');

这样，应该会正确编译并链接到 DLL 文件，并且在运行时能够找到并使用该 DLL 文件。如果还有其他问题，请提供更多详细信息以便进一步排查。
