Angular ''；不被识别为内部或外部命令？

问题：

在angular项目中，我的package.json文件中有这些流动命令

"scripts": {
    "ng": "ng",
    "start": "ng serve --open",
    "start:prod": "npm run build:prod && npm run server",
    "build": "ng build",
    "build:prod": "ng build --prod",
    "lint": "ng lint",
    "test": "ng lint && ng test --configuration=test",
    "watch": "ng test --configuration=test --browsers ChromeHeadless --watch --reporters dots",
    "e2e": "ng e2e",
    "e2e:ci": "ng e2e --webdriver-update false",
    "pree2e:ci": "./node_modules/protractor/bin/webdriver-manager clean && ./node_modules/protractor/bin/webdriver-manager update --versions.chrome=62.0.3202",
    "ci": "npm run format:test && ng lint && ng test --configuration=test --browsers ChromeTravisCi --code-coverage && npm run e2e:ci && npm run build:prod -- --deploy-url /angular-ngrx-material-starter/ --base-href /angular-ngrx-material-starter",
    "format:write": "prettier projects/**/*.{ts,json,md,scss} --write",
    "format:test": "prettier projects/**/*.{ts,json,md,scss} --list-different",
    "release": "standard-version && git push --follow-tags origin master",
    "analyze": "npm run build:prod -- --stats-json && webpack-bundle-analyzer ./dist/angular-ngrx-material-starter/stats-es2015.json",
    "server": "node ./projects/server/server.js",
    "contributors:add": "all-contributors add",
    "contributors:generate": "all-contributors generate && node .all-contributors-html.js",
    "contributors:check": "all-contributors check"
  },

但是当我试图运行

npm run pree2e:ci时，它给了我这个错误<代码>”未被识别为内部或外部命令，

。我搜索了很多，但找不到一个有效的理由。当我在bash上点击这个命令时，它正在工作

/node\u modules/dragrator/bin/webdriver manager clean&&./node\u modules/dragrator/bin/webdriver manager update--versions.chrome=62.0.3202

。但当我只是运行npmrun命令时，它就不起作用了。有人能帮我解决这个问题吗。谢谢你

你需要换衣服

"./node_modules/protractor/bin/webdriver-manager clean && ./node_modules/protractor/bin/webdriver-manager update --versions.chrome=62.0.3202"

通过查看文档：

还是一样的问题。当我只是复制命令并用bash运行时，它可以正常工作，但只在npm运行时失败，可能会删除。/node_modules/dragrator/bin/

"./node_modules/protractor/bin/webdriver-manager clean && ./node_modules/protractor/bin/webdriver-manager update --versions.chrome 62.0.3202"
