Question

我正在尝试执行这个简单的量角器示例https://coryrylan.com/blog/introduction-to-e2e-testing-with-the-angular-cli-and-protractor而我正在

webpack: Compiled successfully.
events.js:182
      throw er; // Unhandled 'error' event
      ^

Error: connect ETIMEDOUT 123.123.123.123:443
    at Object._errnoException (util.js:1024:11)
    at _exceptionWithHostPort (util.js:1046:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1185:14)

据我所知，这是因更新webdrive-manager时失败而导致的错误。我自己尝试手动更新，但我仍然遇到同样的错误。

PS C:\_pocs\ws_vsc\ng-pokedex-master> npm install -g webdriver-manager

我认为它不相关，但以下是来自上面项目的package.json。我试过两个“量角器”：“~5.1.1”和5.1.2

}

我想到的其他事情是我的代理配置错误，但我可以成功运行npm install，所以我认为这不会解释我的问题。顺便说一句，这是

H:\>npm config list
; cli configs
metrics-registry = "https://registry.npmjs.org/"
scope = ""
user-agent = "npm/5.5.1 node/v8.8.1 win32 x64"

; userconfig C:\Users\dca\.npmrc
http-proxy = "http://XXX.vm.mycompany.net:3128/"
https-proxy = "http://XXX.vm.mycompany.net:3128/"
proxy = "http://XXX.vm.mycompany.net:3128/"

; builtin config undefined
prefix = "C:\\Users\\dca\\AppData\\Roaming\\npm"

; node bin location = C:\Program Files\nodejs\node.exe
; cwd = H:\
; HOME = C:\Users\dca
; "npm config ls -l" to show all defaults.

Answer 1

根本原因是你的网络在代理后面，你为NPM配置的代理不会对webdriver-manager生效（webdriver-manager不会读取NPM的代理设置）

选项1 ：每次在webdriver-manager命令中添加代理

webdriver-manager update --proxy=http://XXX.vm.mycompany.net:3128

注意：您还需要在执行webdriver-manager start

时添加代理

选项2 ：在环境变量中配置代理，然后您无需在weddriver-manager命令中添加代理。

将以下环境变量添加到用户环境变量（当前登录用户，非系统环境变量）

HTTP_PROXY = http://XXX.vm.mycompany.net:3128/
HTTPS_PROXY = http://XXX.vm.mycompany.net:3128/
NO_PROXY = .mycompany.net,localhost,127.0.0.1

注意：执行此操作后，代理设置将影响从命令窗口执行的每个命令/程序（将访问网络）
