在Angular 5中出现错误后，降级到Angular 4.3.3版本

有没有一个很好的方法来降级

Angular

version？我的

package.json

看起来像：

  "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",
    "bootstrap": "^3.3.7",
    "core-js": "^2.4.1",
    "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"
  }

所以它采用了最新版本的

Angular

——我认为是v.5，它会抛出一些奇怪的错误，比如：

http://localhost:8091/main.(..).bundle.js net::ERR_ABORTED

---

因此，如果可能，我想将项目中的

Angular

版本设置为

v.4.3.3

？或者可能有一个很好的解决上述错误的方法？

删除node_modules文件夹并执行npm install您可以添加一些说明暗示在package.json中更改版本是不够的。由于所有软件包都将下载到node_modules文件夹，最干净的方法是删除该文件夹（linux/mac上的rm-rf），然后运行“npm install”命令再次下载所有软件包。

rm -rf node_modules
npm install
