你似乎不依赖于“@angular/核心”。 打字稿

我试图在npm start上运行一个命令，但是我得到这样的信息：“你似乎不依赖于”@ angular / core“，这是一个错误，原因是什么？ ：npm @ angular / core -v它得到5.4.2

我的package.json

"dependencies": { "@angular/animations": "^4.4.3", "@angular/common": "^4.4.3", "@angular/compiler": "^4.4.3", "@angular/core": "^4.4.3", "@angular/forms": "^4.4.3", "@angular/http": "^4.4.3", "@angular/platform-browser": "^4.4.3", "@angular/platform-browser-dynamic": "^4.4.3", "@angular/router": "^4.4.3", "applicationinsights-js": "^1.0.12", "core-js": "^2.4.1", "date-fns": "^1.28.5", "deepmerge": "^1.5.1", "fingerprintjs2": "^1.5.1", "ng2-page-scroll": "^4.0.0-beta.9", "ngx-mydatepicker": "2.1.2", "rxjs": "^5.1.0", "zone.js": "^0.8.12" }, "devDependencies": { "@angular/cli": "^1.4.2", "@angular/compiler-cli": "^4.4.3", "@angular/language-service": "^4.4.3", "@types/applicationinsights-js": "^1.0.4", "@types/deepmerge": "^1.3.2", "@types/jasmine": "~2.5.53", "@types/jasminewd2": "~2.0.2", "@types/node": "~6.0.60", "codelyzer": "~3.0.1", "gulp": "^3.9.1", "gulp-deploy-git": "^0.5.3", "gulp-replace": "^0.6.1", "husky": "^0.14.3", "jasmine-core": "~2.6.2", "jasmine-spec-reporter": "~4.1.0", "karma": "~1.7.0", "karma-chrome-launcher": "~2.1.1", "karma-cli": "~1.0.1", "karma-coverage-istanbul-reporter": "^1.2.1", "karma-jasmine": "~1.1.0", "karma-jasmine-html-reporter": "^0.2.2", "lint-staged": "^4.0.3", "prettier": "^1.5.3", "protractor": "^5.1.2", "run-sequence": "^2.1.0", "ts-node": "~3.2.0", "tslint": "~5.7.0", "typescript": "^2.5.2" } 

Answer 1

尝试删除node_modules文件夹， package-lock.json文件，然后运行：

 npm cache clean --force npm cache verify npm i 

Answer 2

你需要删除^这个，因为它得到的版本，其他文件影响到这个版本，

所以总是在angular度上使用特定的版本。

或者你可以在这里使用下面的package.json：

 { "name": "artist-booking-app", "version": "0.0.0", "license": "MIT", "scripts": { "ng": "ng", "start": "ng serve", "build": "ng build", "test": "ng test", "lint": "ng lint", "e2e": "ng e2e" }, "private": true, "dependencies": { "@angular/animations": "4.0.0", "@angular/common": "4.0.0", "@angular/compiler": "4.0.0", "@angular/core": "4.0.0", "@angular/forms": "4.0.0", "@angular/http": "4.0.0", "@angular/platform-browser": "4.0.0", "@angular/platform-browser-dynamic": "4.0.0", "@angular/router": "4.0.0", "angular2-toaster": "^4.0.1", "bootstrap": "3.3.7", "core-js": "2.4.1", "jquery": "3.2.1", "ng2-scroll-to-el": "^1.0.0", "primeng": "^4.1.3", "rxjs": "5.4.1", "zone.js": "0.8.14" }, "devDependencies": { "@angular/cli": "1.2.6", "@angular/compiler-cli": "4.0.0", "@angular/language-service": "4.0.0", "@types/jasmine": "2.5.53", "@types/jasminewd2": "2.0.2", "@types/node": "6.0.60", "codelyzer": "3.0.1", "jasmine-core": "2.6.2", "jasmine-spec-reporter": "4.1.0", "karma": "1.7.0", "karma-chrome-launcher": "2.1.1", "karma-cli": "1.0.1", "karma-coverage-istanbul-reporter": "1.2.1", "karma-jasmine": "1.1.0", "karma-jasmine-html-reporter": "0.2.2", "protractor": "5.1.2", "ts-node": "3.0.4", "tslint": "5.3.2", "typescript": "2.3.3" } }

我遇到同样的问题来解决这个所有你需要做的就是

 cd <project_name> 

然后运行以下命令：

 npm update 

而且这个项目将会被成功编译。
