无法使用Protractor webdriver-manager

Question

我正在尝试在我的本地Windows开发机器上启动量角器.为了尝试这样做,我试图使用以下命令从命令行启动它:

C:\myProject\node_modules\grunt-protractor-runner\node_modules\protractor\bin>webdriver-manager start

运行该命令时,我收到一条错误消息:

'webdriver-manager' is not recognized as an internal or external command,
operable program or batch file.

我确信这是正确的.我正在通过NPM安装量角器.我的package.json文件如下所示:

{
  "name": "MyProject",
  "version": "0.0.1",
  "description": "Just the description",
  "repository": "N/A",
  "readme":"N/A",
  "private": true,
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "devDependencies": {
    "grunt-contrib-clean": "~0.5.0",
    "grunt-contrib-concat": "0.4.0",
    "grunt-contrib-connect": "0.7.1",
    "grunt-contrib-copy": "~0.4.1",
    "grunt-contrib-cssmin": "~0.6.1",
    "grunt-contrib-htmlmin": "~0.1.3",   
    "grunt-contrib-jshint": "0.9.2",
    "grunt-contrib-uglify": "~0.2.4",
    "grunt-contrib-watch": "0.5.x",
    "grunt-protractor-runner": "0.2.4",
    "grunt-start-webdriver":"0.0.2",
    "phantomjs": "1.9.7-3",
    "selenium-webdriver":"2.41.0",
    "load-grunt-tasks": "0.2.x",
  },
  "license": "none"
}

我究竟做错了什么？为什么我不能让量角器运行？谢谢!

Answer 1

全局安装量角器.

npm install protractor -g

这将安装protractor和webdriver-manager.然后从命令行运行:webdriver-manager update 检查更多信息:http://angular.github.io/protractor/#/tutorial

Answer 2

webdriver-manager实际上是一个NodeJS脚本.运行它

node webdriver-manager start

Answer 3

尝试以管理员身份全局安装它:

npm install -g webdriver-manager

Answer 4

如果您是 Windows 用户，这可以帮助您：

1. 添加C:\Users\%username%\AppData\Roaming\npm到PATH变量中。

2. 关闭 cmd/powershell 并再次打开它。

3. 尝试 webdriver-manager
