'Error: No update-config.json found' with Docker, Protractor, and SauceLabs

Question

我正在尝试在 Docker 容器中使用 Protractor+SauceLabs 进行自动端到端测试，但收到“错误消息：未找到更新-config.json。运行 'webdriver-manager update' 下载二进制文件。'我现在运行ning 'webdriver-manager update --standalone false' 在运行ning 端到端测试之前，（独立因为我不需要也需要 java 的独立版本）。有趣的是，（可以在下面的命令行输出中看到）该命令有效，我实际上可以找到 update-config.json 文件，但是我仍然遇到相同的错误。这可能只是量角器的一个错误，但我想先检查 Stack Overflow。任何帮助将不胜感激，谢谢！

哦，当然，即使我删除了 nodemodules、运行 npm install 和 npm 运行 e2e sauce，测试也在本地工作，或者清除它们，执行 npm install，npm 运行 webdriver-update 和 npm 运行 e2e-sauce.

相关依赖 "@angular/cli": "1.6.6", "node": "8.10.0", "npm": "5.6.0", "protractor": "5.1.2", "ts-node": "4.1.0",

package.json 命令：

"e2e-sauce": "ng e2e --port 8100 --env test --sauce",
"webdriver-update": "webdriver-manager update --standalone false --gecko false",

bash脚本我是运行ning:

# for testing purposes, normally environment variable
GIT_COMMIT=aTestCommit;

if [[ -z $GIT_COMMIT ]]; then
  echo "$GIT_COMMIT environment variable is required!";
  exit 1;
fi

function cleanup {
  docker rm -f $GIT_COMMIT
}

trap cleanup EXIT INT TERM

COMMAND=""
COMMAND+="npm run webdriver-update"
COMMAND+=" && ls ./node_modules/protractor/node_modules/webdriver-manager/selenium"
COMMAND+=" && ng e2e --port 8100 --env test --sauce"

set -ex

docker-compose create --build builder

docker-compose run --name $GIT_COMMIT builder bash -c "$COMMAND"

Docker文件：

运行宁我的 bash 脚本的命令行输出：

Answer 1

根本原因是 angular cli ng e2e 将默认执行 webdriver-manager update。

并且你使用的是global angular cli而不是项目本地的，所以它会尝试使用global webdriver-manager来执行更新，但是你没有安装global webdriver-manager，所以ng e2e 报告 Error: No update-config.json found.

解决问题的两个选项：

选项 1： 通过添加 --wu false

禁用 ng e2e 的 webdriver-manager update

COMMAND+=" && ng e2e --port 8100 --env test --sauce --wu false"

但是您需要自己更新 webdriver，就像您之前所做的那样。

选项 2：安装 angular cli 作为项目本地包，而不是全局包，通过删除 -g 选项

# Install the Angular CLI globally
RUN npm install @angular/cli@1.6.6

Answer 2

发现这是因为我没有使用独立版本的 selenium（我不应该使用“--standalone false”）。删除该行并在我的 Dockerfile 中安装 java 后，它像梦一样工作。
