【问题描述】：
我正在使用量角器对 Angular 应用程序运行测试。它们适用于我的 OSX 环境，但不适用于 TeamCity 尝试运行它的 Linux。
当我在本地 OSX 环境中运行此命令时，它可以工作（也在我同事的机器上测试过）：
./node_modules/protractor/bin/protractor protractor.conf.js
Using ChromeDriver directly...
..
Finished in 5.55 seconds
2 tests, 2 assertions, 0 failures
当我在 linux 机器上运行它，或者 TeamCity 作业尝试运行它时，它会失败：
./node_modules/protractor/bin/protractor protractor.conf.js
Using ChromeDriver directly...
/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/http/util.js:87
Error('Timed out waiting for the WebDriver server at ' + url));

尝试解决：
我查看了this issue，但独立的 webdriver 服务器不是解决方案。
我查看了this issue，但我的 selenium-wedriver 版本是2.42.1，所以，不是同一个错误。
版本：
$ node --version
v0.10.26
$ ./node_modules/protractor/bin/protractor --version
Version 1.0.0
$ uname -mrs
Linux 3.11.0-15-generic x86_64
进度更新：
试图获取chrome-webdriver的版本暴露了一个问题：
$ ./node_modules/protractor/selenium/chromedriver --version
./node_modules/protractor/selenium/chromedriver: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory
由此我断定存在依赖问题并发现Selenium requires Chrome。 (more).
我使用steps like this在Linux机器上安装了Chrome：
sudo apt-get install libxss1 libappindicator1 libindicator7
sudo wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i google-chrome*.deb
这并没有完全那样工作，但是在与依赖项和sudo apt-get install 反复来回之后，我想我安装了 Chrome：
$ google-chrome --version
Google Chrome 36.0.1985.143
这使得 chromedriver 版本工作：
$ ./node_modules/protractor/selenium/chromedriver --version
ChromeDriver 2.10.267518
但是，运行 Protractor 仍然不起作用：
$ ./node_modules/protractor/bin/protractor protractor.conf.js
Using ChromeDriver directly...
/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/atoms/error.js:109
var template = new Error(this.message);
^
