Question

我想在Angular 2中更新我过时的依赖项。当我运行npm outdated时，它显示了一些过时的依赖项，但是当我尝试使用npm update命令更新它们时，对我来说不起作用。我的npm版本是5.3.0。

Answer 1

你可以试试这个包...

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

然后运行

ncu -u

然后：

删除您的node_modules文件夹并使用npm install重新安装依赖项但我建议你成为carefully ..因为很多时候并非所有依赖关系都适用于最新版本...

通常我使用具有不错功能的VSCODE ...你可以将光标放在package.json中的包上，它会为你提供最新版本的包..所以你可以选择{{ 1}}

希望它可以帮到你

安装包npm-check，可在此处找到：

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

然后，在项目控制台中输入npm-check -u。它会显示交互式菜单，您可以检查要更新的软件包。
