“ng e2e"失败可能是因为代理但“ng serve"；和“ng测试"正在工作 [英] "ng e2e" is failling probably in reason of proxy but "ng serve" and "ng test" are working

问题描述

我下载 https://github.com/blizzerand/pastebin-angular可以成功运行ng test"；或npm run test"(我理解两者的作用完全相同).

I download https://github.com/blizzerand/pastebin-angular and I can successfully run "ng test" or "npm run test" (I understand both do exactly the same).

C:\_pocsws_vscpastebin-angular-master>npm run test

当我尝试ng e2e"时我得到"ETIMEDOUT x.x.x.x:443"

When I try "ng e2e" I get " ETIMEDOUT x.x.x.x:443"

所以我改为ng e2e --no-webdriver-update"因为它根本不依赖代理.

So I change to "ng e2e --no-webdriver-update" since it will no rely on proxy at all.

自从我得到找不到 update-config.json".运行'webdriver-manager update'"然后我尝试下载它并明确使用我的本地代理

Since I got "Could not find update-config.json. Run 'webdriver-manager update' " then I tried downlod it and explicitly use my local proxy

当我看到"时，我有点困惑E/downloader - 预期响应代码 200，收到:403"但最后我看到I/update - selenium Standalone:selenium-server-standalone-3.8.1.jar up to date".我会假设我下载正确.现在我重复ng e2e".我在上面遇到了同样的错误.因为我看到端口号 443，所以我决定尝试一下ng e2e --skip-ssl".我在上面遇到了同样的错误.我也尝试了 ng e2e --webdriver-update=false ，但我仍然得到找不到 update-config.json".

A bit confusing for me when I see " E/downloader - Expected response code 200, received: 403" but at the end I see "I/update - selenium standalone: selenium-server-standalone-3.8.1.jar up to date". I will assume that I download it correctly. Now I repeat "ng e2e" and I got same error above. Since I see port number 443, I decided try something "ng e2e --skip-ssl" and I got same error above. I tried ng e2e --webdriver-update=false as well and I still get "Could not find update-config.json".

我尝试的最后一个尝试是

The last tentative I tried was

我所做的所有尝试都是在 2 天(16 小时)之后努力设置我的环境.据我了解ng 测试"基于 Jasmine sintaxes 和ng e2e"运行测试基于 Protractor sintaxes(我知道这是非常虚拟的比较).

All tentatives I have done was after 2 days (16 hours) struggling to settup my environment. As far as I understand "ng test" run tests based on Jasmine sintaxes and "ng e2e" based on Protractor sintaxes (I know it is very dummy comparasion).

最后，当我看到两个ng serve"时，我发现问题的路径变得更加复杂.和ng测试"运行良好.

Finally, it make my route to find the issue even more complicated when I see that both "ng serve" and "ng test" are working perfectly.

推荐答案

1) 运行ng e2e时报错:Error: connect ETIMEDOUT xxxx:443

因为ng e2e的选项--webdriver-update的默认值为true，而且你的网络在proxy后面，所以不用告诉你的network proxy给webdriver-manager, webdriver-manger 更新将无法连接网络，这就是您看到错误的原因.

because the default value of option --webdriver-update of ng e2e is true, and your network behind proxy, so without telling your network proxy to webdriver-manager, webdriver-manger update will fail to connect network, this's why you see the error.

我在 https://github.com/angular/angular-cli/blob/master/packages/%40angular/cli/tasks/e2e.ts，并注意到我们不能通过后面的npm run e2e来传递代理，但是我们可以在环境变量中设置代理，webdriver-manager会在运行前读取，你可以关注下面的帖子在环境变量中设置代理:如何检查导致 webdriver-manager 失败的原因

I looked into the source code of ng e2e at https://github.com/angular/angular-cli/blob/master/packages/%40angular/cli/tasks/e2e.ts, and noticed we can't pass the proxy by following behind npm run e2e, but we can set proxy in Enviroment Variable which webdriver-manager will read before running, you can follow below post to set proxy in Environment Varable: how to check what is causing webdriver-manager to fail

2) 当你运行ng e2e --no-webdriver-update 跳过webdriver更新时，报错:Error message: Could not find update-config.json

2) when you run ng e2e --no-webdriver-update to skip webdriver update, it report error: Error message: Could not find update-config.json

表示project_folder ode_modulesprotractor ode_moduleswebdriver-managerselenium中不存在update-config.json

It means the update-config.json not exist in project_folder ode_modulesprotractor ode_moduleswebdriver-managerselenium

因为您使用全局 webdriver-manger 来执行 webdriver 更新，而不是项目本地 webdriver-manager(位于 project_folder.binwebdriver-manager).

Because you used the global webdriver-manger to execute webdriver update, rather than the project local webdriver-manager (at project_folder.binwebdriver-manager).

正确的做法是先在cmd窗口切换到your_project文件夹，然后执行node_modules.binwebdriver-manager update --proxy http://myproxy.vm.mycompany.网:3128然后 update-config.json 将在那里并且 ng e2e --no-webdriver-manager 现在应该可以工作了.

The correct way is switch to your_project folder in cmd window firstly, then execute node_modules.binwebdriver-manager update --proxy http://myproxy.vm.mycompany.net:3128 Then the update-config.json will be there and ng e2e --no-webdriver-manager should work now.

ng e2e不能使用全局webdriver-manager，只能工程本地node_modules.binwebdriver-manger

ng e2e can't use global webdriver-manager, but only project local node_modules.binwebdriver-manger

npm 代理 VS 环境变量代理

1) npm 代理

npm proxy 仅适用于命令:npm 并且该命令实现不会从 evniroment 变量中读取代理，因此您必须通过命令 npm config set 或直接修改用户 home 或项目文件夹下的 .npmrc 文件.

npm proxy only work for the command: npm and this command implement won't read proxy from evniroment variable, thus you have to set proxy for npm by command npm config set or directly modify .npmrc file under user home or project folder.

2) 环境变量代理

只有实现的工具/软件/程序/命令会从环境变量中读取代理设置，然后环境变量代理才能对其产生影响.

Only tool/soft/program/command which implement will read proxy setting from environment variable, then the environment variable proxy can effect on them.

用户很难知道环境变量代理会影响工具/软件/程序/命令，尤其是我们第一次接触的新事物.

It's not easy for user to know environment variable proxy will effect on a tool/soft/program/command, especially it's a new thing we touch for first time.

但一般情况下，我们可以认为从命令窗口执行的所有操作都会从环境变量中读取代理设置，但并不总是这样，就像 npm 一样，它只是从自己的代理设置中读取代理.

But in generally, we can think everything executed from command window will read proxy setting from environment variable, but it's not always this, Like npm, it only read proxy from itself proxy setting.

现在回到webdriver-manager，在大多数情况下它首先从命令窗口执行，实际上决定环境变量代理是否影响它的最终决定者是实现本身.

Now back to the webdriver-manager, first it executed from command window in most case, actually the final determiner to decide environment variable proxy will effect on it or not is the implement itself.

在webdriver-manager实现中，首先会读取命令行中作为选项传递的代理，如下: webdriver-manager update --proxy http://proxy.company.com:1234

In webdriver-manager implement, firstly, it will read proxy passed as options in command line as following: webdriver-manager update --proxy http://proxy.company.com:1234

如果你没有在命令行中传递代理，那么它将从环境变量中读取代理.

If you not pass proxy in command line, then it will read proxy from environment variable.

这篇关于“ng e2e"失败可能是因为代理但“ng serve"；和“ng测试"正在工作的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
