我刚安装MacOS的莫哈韦沙漠，并安装最新版本node 12.1.0，npm 6.9.0，brew 2.1.1和Python 2.7.10 on darwin。我在 package.json 中为项目运行 npm install"sqlite3": "4.0.6" 并收到以下日志消息，该消息在 sqlite3@4.0.6 安装脚本中失败。如何修复错误并成功安装 SQLite？它正在破坏并在 v8 函数中显示错误日志，这是错误日志的部分快照，我删除了一些 v8 错误以发布日志。

我试图映射对象数组，每个数组包含另一个嵌套的对象数组。但是，该映射不适用于嵌套数组。如何在嵌套数组的内容上进行映射，同时保持所有父对象content的相同title？
