angular-cli项目上的npm install问题

Question

I have angular-cli project with node modules installed that is working properly. When I pulled project to new directory i am able to to do npm install with following warnings:

    npm WARN deprecated angular-cli@1.0.0-beta.26: angular-cli has been renamed to @angular/cli. Please update your dependencies.
    npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

    npm WARN @angular/compiler-cli@2.4.9 requires a peer of @angular/core@2.4.9 but none was installed.

I am using angular 2.4.4.why is 2.4.9 mentioned in warnings? I am afraid that some dependencies are not installed. And that's why my application is not working properly on ng serve. I don;t want to update angular-cli to RC1 since it may have more issues with dependencies. What should I do?

current versions on system:

angular-cli: 1.0.0-beta.26
node: 6.9.4
os: win32 x64
@angular/common: 2.4.4
@angular/compiler: 2.4.4
@angular/core: 2.4.4
@angular/forms: 2.4.4
@angular/http: 2.4.4
@angular/platform-browser: 2.4.4
@angular/platform-browser-dynamic: 2.4.4
@angular/router: 3.4.4
@angular/upgrade: 2.4.4

Answer 1

可能是npm试图使用最新的可用版本，因为在package.json上存在依赖关系。如果使用严格的设置版本，例如"@angular/common": "2.4.0"则"@angular/common": "^2.4.0"会写为"@angular/common": "^2.4.0" "@angular/common": "2.4.0"一切正常。

Updating to the RC will make the life easy while developing. Since ng-update and ng-init are removed temporarily from the CLI you might have to manually update it. But, it's worth the time. I assume that issue is with the version. Updating the packages will solve the issue.

Also, If you look at the console, the warnings are suggesting you install some packages globally. Also, considering about upgrading there might be breaking changes that will take a bit of time but, not much. Since the version is beta.26 It won't take much time.

Otherwise, for now following Michael M s answer might temporarily solve the issue.
