好吧，当我使用 npm 安装一些依赖项或一些库时，有时，在命令提示符中我会收到一些错误或警告，如下所示：

npm WARN angular-datatables@6.0.0 requires a peer of @angular/common@^6.0.0 but none is installed. You must install peer dependencies yourself.

我使用了 npm install moment.js --save

库，在本例中：'moment.js' 非常好用！但我的疑问是，有什么建议吗？

【问题讨论】：

Npm peer dependency error的可能重复
Momentjs 效果很好，在您发布的输出中没有报告任何问题。但是警告实际上是关于角度数据表的依赖关系可能不会。

【解决方案1】：

NPM 会警告您，因为 angular-datatables 需要对等依赖项，模块需要运行的特定依赖项但这些只是警告，如果一切正常，您不需要自己安装这些对等依赖项。
