node-gyp 构建给出未解决的外部符号错误
node-gyp build gives unresolved external symbol error
我正在尝试访问 C++ 代码形式 javascript 并且我使用了 swig。现在，当我尝试 运行 命令 node-gyp configure build 时，出现以下错误。任何人都可以在这里帮助我并告诉我为什么会这样

GYP 是一个 meta-build 系统，它为各种构建系统生成文件，在您的情况下为 MSBuild。在您的情况下，稍后会在 MSBuild 级别发生错误，而不是 node-gyp 级别。
您正在使用某些 headers，其中定义了所有这些函数，但未针对相应的 *.lib 库或 *.c/.cpp linking来源。
您的库似乎是与文档扫描设备相关的专有库。
您可以 link 通过使用 GYP 文件的 libraries 部分来修复这个丢失的库：
'libraries': ['mylibrary.lib']
然后重建 MSBuild 文件：
node-gyp configure
