无法在 Selenium Standalone 上创建 FF/Chrome 会话

Question

机器详细信息

AME="Amazon Linux AMI"
VERSION="2017.03"
ID="amzn"
ID_LIKE="rhel fedora"
VERSION_ID="2017.03"
PRETTY_NAME="Amazon Linux AMI 2017.03"
ANSI_COLOR="0;33"
CPE_NAME="cpe:/o:amazon:linux:2017.03:ga"
HOME_URL="http://aws.amazon.com/amazon-linux-ami/"

我是单独使用 selenium 的新手。我已经下载了最新的 java 版本，独立使用 NPM，XVFB 并尝试在使用以下命令打开独立后创建会话：

sudo xvfb-run --server-args="-screen 0, 1366x768x24" selenium-standalone start -- -debug

另请注意，我已尝试使用 Hub 和 Node 进行此操作，还尝试在我的本地客户端上使用 C# 运行 Selenium 测试。

当我尝试创建 Chrome 会话时收到此错误（轮询将持续几秒钟）：

尝试运行此命令安装最新的稳定版GoogleChrome：

sudo yum -y localinstall google-chrome-stable_current_x86_64.rpm

或

wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

我收到此错误：

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

有没有人遇到过这个问题并且无论如何都可以解决这个问题？如果您有任何问题，请告诉我。

Answer 1

我无法在 Linux AMI 上安装这些库，但我最终将其安装在 Ubuntu 实例上。这使得使用以下文档的安装非常简单： https://www.npmjs.com/package/selenium-standalone

但是，我的 Ubuntu linux 也收到了一个二进制错误。问题是我的 Linux 机器上没有安装浏览器，但我可以使用此处的说明进行安装： https://askubuntu.com/questions/510056/how-to-install-google-chrome

也适用于 FireFox：

#install firefox browser
sudo apt-get install firefox
