node-gyp構建提供了未解決的外部符號錯誤

Question

我正嘗試使用swig訪問c ++代碼形式的javascript。 現在，當我嘗試運行命令node-gyp configure build ，出現以下錯誤。 任何人都可以在這里幫助我，並說明為什么會這樣

GYP是一個元構建系統，為您的情況下的各種構建系統MSBuild生成文件。 就您而言，稍后在MSBuild級別而不是node-gyp級別會發生錯誤。

您正在使用某些標頭，其中定義了所有這些功能，但未鏈接到相應的*.lib庫或*.c / .cpp源。

您的庫似乎是與文檔掃描設備有關的專有庫。

您可以使用GYP文件的“ libraries部分鏈接到此缺少的庫：

'libraries': ['mylibrary.lib']

然后重建MSBuild文件：

node-gyp configure
