“'npm update”命令无法更新Angular2中的依赖项

Question

我想要在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，但当我尝试用npm update命令更新它们时，它对我不起作用。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，但我建议您多次使用carefully ..cause，并不是所有的依赖项都可以解决到最新版本……

我通常使用VSCODE，它有一个很好的功能…您可以将光标放在package.json中的包上，它将为您提供包的最新版本。所以你可以选择manually

希望能对你有所帮助

安装npm-check包，可以在这里找到：

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

然后，在项目控制台中输入npm-check -u。它将显示交互式菜单，您将能够检查您想要更新的包。
