问题描述
问题：
在我的有角项目中，我的package.json文件中有这些流动的命令。
"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,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"
},但是当我尝试运行npm run pree2e:ci时，出现了这个错误。 .' is not recognized as an internal or external command,。我进行了很多搜索，但是找不到有效的原因。当我刚击中该命令时，它就起作用了。 ./node_modules/protractor/bin/webdriver-manager clean && ./node_modules/protractor/bin/webdriver-manager update --versions.chrome=62.0.3202。但是，当我只运行npm run命令时，它不起作用。有人可以帮我解决这个问题吗？ 。谢谢
解决方法
您需要更改
"./node_modules/protractor/bin/webdriver-manager clean && ./node_modules/protractor/bin/webdriver-manager update --versions.chrome=62.0.3202"
请参阅文档：link
"./node_modules/protractor/bin/webdriver-manager clean && ./node_modules/protractor/bin/webdriver-manager update --versions.chrome 62.0.3202"
