幾個未被遵守的對等依賴性錯誤，包括@ angular/common @ 2.4.9

Question

過去幾天我一直在爲包依賴而苦苦掙扎，我的目標是使用angular2-busy，但是我開始閱讀它，我想我有一個更大的整體問題。

無論何時我運行「npm list」，我都會收到一堆UNMET PEER DEPENDENCY消息。

我想開始清理，最多和第一個條目是：

"UNMET PEER DEPENDENCY @angular/common@2.4.9" 

我試着重新安裝@角/常見，但沒有任何區別，可能有人向我解釋什麼是實際問題在這裏，所以我可以開始清理所有這些了嗎？

謝謝。

冷酷地想要做什麼？

npm list用於列出已安裝的軟件包，它不會安裝/更新任何內容。

你應該做npm install或npm update

我抄你的package.json並執行以下命令行：

npm cache clean 
npm install 
npm update 

和一切正常！

要檢查的依賴版本嘗試使用npm-check-updates

要安裝使用這個命令：

npm install -g npm-check-updates 

運行命令行安裝ncu後，你會看到什麼是包的最新版本。

後更新至最新版本的package.json這個樣子的一兩件事：
