英文:
npm ERROR trying to run a project in Angular
问题
我试图用 ng serve -o 运行我的项目。问题是屏幕上出现了以下警告：
您的全局 Angular CLI 版本（15.2.2）大于您的本地版本（15.0.4）。将使用本地 Angular CLI 版本。
要禁用此警告，请使用“ng config -g cli.warnings.versionMismatch false”命令。
我使用 install -g @angular/cli 重新安装了 Angular，然后使用 npm install --save-dev @angular/cli@latest 升级了我的本地版本，但是当我输入该命令时，出现了以下内容：
C:\Users\user1\Dropbox\Angular\myApp>npm install --save-dev @angular/cli@latest

我不知道该怎么办，请问我该如何解决这个问题？
英文:
I'm triying to run my project with ng serve -o. The problem is that the following warning appears on the screen:
Your global Angular CLI version (15.2.2) is greater than your local version (15.0.4). The local Angular CLI version is used.
To disable this warning use "ng config -g cli.warnings.versionMismatch false".
I reinstalled angular with install -g @angular/cli and then use npm install --save-dev @angular/cli@latest for upgrade my local version but, when I enter the command the following appears:
C:\Users\user1\Dropbox\Angular\myApp>npm install --save-dev @angular/cli@latest

I don't know what I can do, so please how I can resolve this problem?
答案1
得分: 1
答案就在错误信息中：
npm ERR! 修复上游依赖冲突，或使用 --force 或 --legacy-peer-deps 选项重试此命令
npm ERR! 以接受错误的（可能是破损的）依赖解决方案。
当你运行 npm i 时，由于对等依赖版本不匹配，你需要指定 --force 或 --legacy-peer-deps，或者你需要在项目根目录创建一个 .npmrc 文件，并添加：
legacy-peer-deps=true
一旦你的版本不匹配的依赖问题解决了，你就不会再遇到这个错误。
英文:
The answer is in the error itself:
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.
When you run npm i, you need to specify --force or --legacy-peer-deps due to peer dependency version mismatches, or you need to create an .npmrc file in your project root with:
legacy-peer-deps=true
Once your version mismatches with dependencies are resolved, you won't get this error.
