在Node.JS应用程序中编译C ++ / CLI时出错

Question

我需要在Node.JS应用程序中编译托管C ++模块。我在网上阅读了我需要使用/ clr标志启用CLI的信息，并设置了msvs-settings和msbuild_settings属性，但它仍然对我不起作用。我收到此错误消息：

cl：命令行错误D8016：'/ clr'和'/ EHs'命令行选项不兼容[C：\ MyProject \ native-modules \ encryption-utilities \ addon \build \ encrypt.vcxproj]

我已经从此页面获取信息：https://github.com/nodejs/node-gyp/issues/568

这是我的binding.gyp。

谢谢。

我对node.js或.gyp文件了解不多，但我确实知道您遇到的错误。 D8016表示“ / clr表示/ EHa，并且不能使用/ clr指定任何其他/ EH编译器选项”。当您导入旧项目文件或将/clr添加到现有项目时，可能会出现此问题。

解决它的官方方法是在Visual Studio中打开有问题的.vcxproj项目文件，导航到项目属性/配置属性/ C / C ++ /代码生成，然后从中更改启用C ++异常] “ 是具有外部C函数（/ EHs）”到“ 是具有SEH异常（/ EHa）”。]

要在VS之外执行此操作，请在任何文本（或xml）编辑器中打开.vcxproj文件，然后删除以下行：

<ExceptionHandling>SyncCThrow</ExceptionHandling>
或替换为：

<ExceptionHandling>Async</ExceptionHandling>
