'npm update'命令無法更新Angular2中的依賴關係

Question

我想在Angular 2中更新我過時的依賴關係。當我運行npm outdated時，它顯示了一些過時的依賴關係，但是當我嘗試使用npm update命令更新它們時，爲了我。我的npm版本是5.3.0。

Answer 1

你可以試試這個包...

https://www.npmjs.com/package/npm-check-updates 

，然後運行

ncu -u 

則：

刪除你的文件夾node_modules並重新安裝依賴與npm install 但我建議你爲carefully ..因爲很多時候不是所有的依賴關係都解決了最新版本都很好...

我通常使用VSCODE其中有一個很不錯的功能...你可以把光標放在包中的package.json，它給你最新版本的包..所以你可以選擇manually

希望它可以幫助你

安裝包npm-check，它可以在這裏找到：

https://www.npmjs.com/package/npm-check

然後，在你的項目的控制檯類型npm-check -u。它會顯示交互式菜單，您可以檢查要更新的包。
