过去几天我一直在努力解决软件包依赖问题，我的目标是使用angular2-busy但我开始阅读它并且我认为我有更大的整体问题。
当我运行“npm list”时，我收到了一堆UNMET PEER DEPENDENCY消息。
我想开始清理它，第一个条目是：
"UNMET PEER DEPENDENCY @angular/common@2.4.9"
我尝试重新安装@ angular / common但是没有任何区别，有人可以向我解释这里的实际问题是什么，所以我可以开始清理所有这些了吗？
感谢。

你要做的所有事情都是冷杉吗？
npm list用于列出已安装的软件包，它不会安装/更新任何内容。
您应该npm install或npm update
我已经复制了你的package.json并执行了这些命令行：
npm cache clean
npm install
npm update
一切正常！
要检查依赖项版本，请尝试使用npm-check-updates
要安装，请使用此命令：
npm install -g npm-check-updates
从命令行安装后运行ncu，您将看到最新版本的软件包。
关于npm版本号的另一件事，请查看本文Node and npm Version Numbering: Guide and Best Practices
更新到最新版本后，您的package.json如下所示：
