那些遇到过的问题

带有角材料声明的角编辑警告

Ard*_*zii 33 angular-material hyperledger-composer angular

在安装Angular Material之后尝试进行编译时，我遇到了一系列警告（无论是直接来自npm还是通过，ng add @angular/material以及是否选择使用动画）。

它可以正常工作而没有任何警告或问题。有人可以帮助我吗？

以下是警告：

您将需要结合Reid和Jens Mander的答案

按以下顺序执行：

npm update @angular/cli @angular/cdk rxjs
npm install -S @angular/material @angular/cdk @angular/animations
npm uninstall @angular/core
npm install -S @angular/core

Angular材料开始为我工作之后

  • 如果在更新过程中，您的角度版本从7切换到8，则还需要运行以下命令：ng update @ angular / cli @ angular / core (2认同)

如果您拥有Angular 7，那么您也应该拥有Angular Material Version 7。所以请安装

npm install @angular/material@7.3.7 
npm install @angular/cdk@7.3.7

如果您有package.json-file删除node_modules文件夹，请在控制台中输入npm install。这应该重新安装所有的node_modules。之后，警告消失了。

我也有同样的问题，然后我更改了角形材质的版本。

选项1 :: 您可以使用以下命令来更改角度材质的版本。

npm install --save @angular/material@7.3.7
npm install --save @angular/cdk@7.3.7

您可以在角形材料上查看所有版本列表

选项2： 尝试将角度版本从7更新到8

小智 7

这是一个版本控制问题。如果您打算使用Material 8.0.0，那么您将需要同步版本的补充软件包。请尝试以下方法。

npm update @angular/cli @angular/cdk rxjs

上面的命令完成运行后，从Angular Material文档中运行以下命令

npm install --save @angular/material @angular/cdk @angular/animations
Run Code Online (Sandbox Code Playgroud)

这应该使Angular，Material和RxJS的所有版本保持同步，并准备让您开始在Angular 8项目中使用Angular Material和RxJS。

作为一般的更新检查思路，当您更新Angular或其他任何内容以及相应的软件包时，这些问题一直在弹出。当每个难题都经过测试并且稳定时，像现在一样，尝试在主要版本更新上拉动触发器，这样可以避免卡在依赖地狱中，在该依赖地狱中，应用程序的一部分将不匹配，并使您无法继续建立你想要的。

  • 好的，我不知道自己做了什么，但是以下操作有所帮助：npm卸载@ angular / core，然后npm安装@ angular / core。package.json已修改。 (3认同)

只需在package.json中进行一些更改：

@angular/cdk": "^7.0.3"
@angular/material": "^7.0.3"

这些应该与您的角度版本匹配。
