CircleCI/Sauce Labs 代理工作但不运行 Grunt 任务

Question

我正在尝试与 Sauce Labs 集成以运行我的项目的量角器测试，using CircleCI's guide as a basis。测试包含在 Grunt 任务中，该任务在我的机器上完美运行：

grunt.registerTask('test:protractor', [
    'ngconstant:dev',
    'modernizr:prod',
    'sass',
    'protractor'
]);

这是我的 circle.yml 文件：

dependencies:
  pre:
    - sudo apt-get update; sudo apt-get install ruby-sass
    - npm install -g bower
    - bower install
  post:
    - wget https://saucelabs.com/downloads/sc-latest-linux.tar.gz
    - tar -xzf sc-latest-linux.tar.gz

test:
  override:
    - cd sc-*-linux && ./bin/sc --user $SAUCE_USERNAME --api-key $SAUCE_ACCESS_KEY --readyfile ~/sauce_is_ready:
        background: true
    # Wait for tunnel to be ready
    - while [ ! -e ~/sauce_is_ready ]; do sleep 1; done
    - grunt test:protractor
        background: true
  post:
    - killall --wait sc  # wait for Sauce Connect to close the tunnel

The Sauce Connect proxy clearly works according to build output:

30 May 18:18:46 - Started scproxy on port 35557.
30 May 18:18:46 - Please wait for 'you may start your tests' to start your tests.
30 May 18:19:03 - Provisioned tunnel:4b38b707d2174ebf9714f05cd8c06f79
30 May 18:19:03 - Using no proxy for connecting to tunnel VM.
30 May 18:19:03 - Starting Selenium listener...
30 May 18:19:03 - Establishing secure TLS connection to tunnel...
30 May 18:19:03 - Selenium listener started on port 4445.
30 May 18:19:04 - Sauce Connect is up, you may start your tests.

但到那时，它完全停止了。没有努力调用 grunt test:protractor，没有任何活动。 10 分钟后，我终止了构建。

通过 Sauce Labs 代理运行 Protractor 测试的配置中缺少什么？

也许你忘了安装 grunt

dependencies:
  pre:
    - npm install -g grunt
