Angular 2升级到RC 5-未满足的对等依赖

Question

I need to upgrade my angular to rc5 to use NgModule.

I have followed directions from Angular 2 .

I have updated my package.json dependencies to this and then ran npm stall in the terminal:

  "dependencies": {
    "@angular/common": "^2.0.0-rc.5",
    "@angular/compiler": "^2.0.0-rc.5",
    "@angular/core": "^2.0.0-rc.5",
    "@angular/forms": "0.3.0",
    "@angular/http": "2.0.0-rc.5",
    "@angular/platform-browser": "^2.0.0-rc.5",
    "@angular/platform-browser-dynamic": "^2.0.0-rc.5",
    "@angular/router": "3.0.0-beta.1",
    "@angular/router-deprecated": "2.0.0-rc.2",
    "@angular/upgrade": "2.0.0-rc.5",
    "angular2-google-maps": "^0.12.0",
    "angular2-in-memory-web-api": "0.0.14",
    "bootstrap": "^3.3.6",
    "core-js": "^2.4.0",
    "jquery": "v3.1.0",
    "ng2-select": "^1.0.3",
    "reflect-metadata": "^0.1.3",
    "rxjs": "5.0.0-beta.6",
    "systemjs": "0.19.27",
    "zone.js": "^0.6.12"
  },

terminal results:

I have tried the other option suggested by Angular 2:

npm install @angular/{core,common,compiler,platform-browser,platform-browser-dynamic} --save

No matter what I do to upgrade, I get the same unmet peer dependencies errors.

To fix that I have tried:

npm install @angular

result:

Note that this is a working angular 2 app so I do seem to have angular 2 installed. How do I meet my peer dependencies so that I can upgrade to angular2 rc5?

Answer 1

Have you tried a fresh npm install ? Definitely would recommend. Also try to clean the cache beforehand to ensure you have no prior conflicts:

rm -rf node_modules/
npm cache clean
npm install

Also I'd recommend updating your router to 3.0.0-rc.1 . That's the most recent version.

EDIT: I'd also recommend just deleting your node_modules directory and getting a fresh one with the install: rm -rf node_modules .

Answer 2

the reason you are getting this error is because you are using "angular2-google-maps": "^0.12.0" along with angular2. now "angular2-google-maps" is peer dependent on angular 2.0.0-rc.2 version that's what the error states :

npm WARN EPEERINVALID angular2-google-maps@0.12.0 requires a peer of @angular/common@2.0.0-rc.2 but none was installed.

this is still an open issue as seen here .

• I would suggest you to either use angular 2.0.0-rc.2 till it gets resolved.
• Second would be to use npm i https://github.com/SebastianM/angular2-google-maps/tarball/0.12.0 --save for installation of google-maps.

hope it helps!

EDIT : they are releasing 0.13.0 version which would be compatible with rc5 in couple of days. for more info look here

Answer 3

如果您仍然遇到问题，请尝试

npm --depth Infinity update

Answer 4

Here is the same issue which I was also facing-

I just update npm-

sudo npm install npm -g

My issue got resolved !!!
