有关我的设置的一些有用信息：

该项目是使用Anguliar CLI创建的
量角器安装在全球和本地

以下文件位于

节点模块/webdriver管理器/selenium

目录中：

chromedriver_2.32.exe、chromedriver_2.32.zip、chrome-response.xml、gecko-response.json、selenium-server-standalone-3.5.3.jar、standalone response.xml

我使用代理属性运行
```
webdriver管理器更新
```
如果使用正在运行的Selenium网格或使用
```
directConnect:true
```
配置运行该命令，则没有区别
由于浏览器设置为Chrome（Firefox也有同样的问题）

这是我第一次尝试用角度和量角器开发E2E测试

谢谢你的支持

更新

我不知道如果我运行

nge2e

，将执行

webdriver管理器更新。所以我尝试了nge2e——不更新webdriver
，使用这个命令，上面的错误就不会再出现了。我认为出现错误是因为未设置代理，并且webdriver管理器无法运行更新
然而，现在我得到了一个新的错误。下面是完整的输出：
$ ng e2e --no-webdriver-update

好的，我能解决这个问题。这就是我所做的
ng e2e
运行webdriver-manager-update
命令。在我的例子中，这导致了ETIMEDOUT
问题，因为在没有代理的环境中，它无法下载文件。相反，我必须使用nge2e——不更新webdriver

现在我遇到了找不到update config.json
错误
使用--proxy
参数更新webdriver manager似乎无法下载所有内容和/或进行正确的操作。我必须设置环境变量HTTP\u PROXY
和HTTPS\u PROXY
，并运行命令webdriver manager update--ignore\u ssl

现在量角器正在工作。
我发现webdriver管理器更新
尊重HTTPS\u代理
环境变量。尝试使用您的（公司）代理服务器设置HTTPS\u PROXY
环境变量http://********:80
重新启动VS代码或命令提示符（以拾取更改），您应该可以毫无问题地运行e2e测试。
如果您在webstorm或Intellij编辑器中。您可以设置HTTPS_代理变量，也可以在webstorm终端中设置
SET https_proxy=http://yourcompanydomain.com:portnumber
SET http_proxy=http://yourcompanydomain.com:portnumber 

然后在终端中运行以下命令
ng e2e

在我的案例中，问题与公司代理有关。webdriver manager update
命令遇到超时。无论是在.npmrc中设置代理还是像下面这样使用命令行都不起作用
无效解决方案：
SET http_proxy=http://xxx.xxxxxx.xxx:8080

SET https_proxy=http://xxx.xxxxxx.xxx:8080

工作解决方案：为命令提供一个--proxy
标志：
webdriver-manager update --proxy=http://xxx.xxxxxx.xxx:8080

这是
中的正确答案，为我们做了诀窍，事实上，如果您支持corporate proxy，这将解决驱动程序更新问题。这很有效！我将HTTP_代理和HTTPS_代理设置为我的公司代理，然后使用Angular CLI创建了一个新项目。现在，我只需使用ng e2e命令即可运行测试，无需禁用webdriver更新和/或使用--proxy标志手动更新。
