npm安装错误:包不能满足其兄弟姐妹的peerDependencies要求

Question

当我运行npm安装时，我会得到以下错误：

npm ERR! peerinvalid The package @angular/core@7.2.15 does not satisfy its siblings' peerDependencies requirements! npm ERR! peerinvalid Peer @angular/animations@7.2.15 wants @angular/core@7.2.15

安装版本的@角/核心确实是7.2.15，但它的依赖@角/动画说，它需要版本@角/核心7.2.15

有什么想法吗？

我试着卸载/重新安装@转角/核心，但仍然得到相同的错误。

我的package.json：

{ "name": "", "version": "0.0.0", "private": true, "dependencies": { "@angular/animations": "~7.2.0", "@angular/common": "~7.2.0", "@angular/compiler": "~7.2.0", "@angular/core": "~7.2.0", "@angular/fire": "^5.1.1", "@angular/forms": "~7.2.0", "@angular/platform-browser": "~7.2.0", "@angular/platform-browser-dynamic": "~7.2.0", "@angular/router": "~7.2.0", "@aws-amplify/ui": "^1.0.17", "@ngrx/store": "~7.2.0", "@types/pdfjs-dist": "^2.0.0", "aws-amplify": "^1.1.22", "aws-amplify-angular": "^2.1.9", "babel-polyfill": "^6.26.0", "core-js": "^2.5.4", "date-fns": "^1.30.1", "jquery": "^3.3.1", "firebase": "^5.8.3", "materialize-css": "^1.0.0", "ng2-pdf-viewer": "^5.2.4", "ngx-swiper-wrapper": "^7.2.1", "ngx-take-until-destroy": "^5.4.0", "pdfjs-dist": "^2.0.943", "rxjs": "~6.3.3", "tslib": "^1.9.0", "zone.js": "~0.8.26" }, "devDependencies": { "@angular-devkit/build-angular": "~0.13.0", "@angular/cli": "~7.3.0", "@angular/compiler-cli": "~7.2.0", "@angular/language-service": "~7.2.0", "@aws-amplify/cli": "^1.1.7", "@types/jasmine": "~2.8.8", "@types/jasminewd2": "~2.0.3", "@types/node": "^8.10.43", "@types/materialize-css": "^1.0.6", "codelyzer": "~4.5.0", "jasmine-core": "~2.99.1", "jasmine-spec-reporter": "~4.2.1", "karma": "~3.1.1", "karma-chrome-launcher": "~2.2.0", "karma-coverage-istanbul-reporter": "~2.0.1", "karma-jasmine": "~1.1.2", "karma-jasmine-html-reporter": "^0.2.2", "protractor": "~5.4.0", "ts-node": "~7.0.0", "tslint": "~5.11.0", "typescript": "~3.2.2" } }

尝试以下命令：

1.更新npm "npm install npm -g"

2.更新角度npm i -g @angular/cli

3.清除缓存：npm cache clear

4.删除你的node_modules，rm -rf node_modules，

5.再安装一次，npm install。
