节点js应用程序在uv_try_write中崩溃，而在SIGPIPE上使用node C++插件。我如何处理/防止这个问题？

Question

当OS发送SIGPIPE时，我面临一个节点应用程序崩溃的问题。我使用N C++附件发送/接收消息到套接字，使用函数回调。有没有办法找出根本原因或处理同样的，以便应用程序不会崩溃或防止问题的根本原因？

在构建本机模块时验证PIC(独立位置代码)设置是否打开。如果当前关闭，则尝试将其设置为打开，然后重新构建包。如果使用的是Cmake.js，则可以使用以下设置。

set_target_properties(${PROJECT_NAME} PROPERTIES POSITION_INDEPENDENT_CODE ON)
