关于更新我的角度项目的问题

Question

我需要更新我的 Angular 项目，但我遇到了一些问题。 它向我显示以下消息：

Your global Angular CLI version (8.0.1) is greater than your local
version (1.7.4). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

Error: Cannot update safely because packages have conflicting dependencies. Package @angular/core would need to match both versions "7.2.15" and "8.0.0, which are not compatible.

在升级您的 Angular 项目时，只需运行以下命令：

ng update

否则，如果您只想在 CLI 上执行升级，您可以选择特定的软件包

ng update @angular/cli

或者直接通过npm安装

npm install --save-dev @angular/cli

如果您需要进行硬重置，您可以先全局安装 CLI，然后更新项目本身中的 CLI。

npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@latest

那么，你cd到我们的项目目录，

rm -rf node_modules dist 
npm install --save-dev @angular/cli@latest
npm i 
ng update @angular/cli 
ng update @angular/core
npm install --save-dev @angular-devkit/build-angular
