Question

我正在尝试设置一个jenkins服务器，以在Amazon Linux上使用Selenium-webdriver（3.142.0）和ruby（2.3.7）托管我的自动化框架。如果我尝试使用脚本调用chromedriver，它会显示

“ Selenium :: WebDriver :: Error :: UnknownError：未知错误：Chrome无法启动：异常退出（未知错误：DevToolsActivePort文件不存在）（该进程从chrome位置/ usr / bin / google-chrome开始不再运行，因此ChromeDriver假定Chrome崩溃了。）（驱动程序信息：chromedriver = 74.0.3729.6（255758eccf3d244491b8a1317aa76e1ce10d57e9-refs / branch-heads / 3729 @ {＃29}），platform = Linux 4.14.104-95.84.amzn2.x86_64 x86_64）”。

我将chromedriver放置在'/ var / lib / jenkins / driver / chromedriver'下，并在.bashrc中为其设置了PATH，还为它创建了一个符号链接到'/ usr / bin / google-chrome '。以下是我正在使用的计算机的详细信息：

import plotly.graph_objs as go
from plotly.offline import plot

value = [3,5,2,4,6]
source = [0,0,1,0,3]
target = [1,4,2,3,4]
color = ["blue","yellow","orange","orange","purple"]
label = ["A","B","C1","C2","D"]


data = dict(
    type='sankey',
    arrangement = 'freeform',
    node = dict(
      pad = 15,
      thickness = 20,
      line = dict(
        color = "black",
        width = 0.1
      ),
      groups = [[2,3]],
      label = label,
      color = color,
    ),
    link = dict(
        source = source,
        target = target,
        value = value,
      )
)

layout =  dict(
    title = "Sankey test",
    font = dict(
      size = 10
    )
)
f = go.FigureWidget(data=[data], layout=layout)
plot(f)

require 'selenium-webdriver'
options = Selenium::WebDriver::Chrome::Options.new
options.add_argument("--disable-dev-shm-usage");
options.add_argument('--no-sandbox')
driver = Selenium::WebDriver.for :chrome, options: options

Answer 1

Chrome未安装在默认位置。对于Linux系统，ChromeDriver检查Chrome是否安装在默认位置/usr/bin/google-chrome中。如果您在非标准位置使用Chrome，则需要覆盖Chrome二进制位置。

caps = Selenium::WebDriver::Remote::Capabilities.chrome("chromeOptions" => {"binary" => "Actual Path"})

如何修复Linux中的“ usr / bin / google-chrome不再运行，因此ChromeDriver认为Chrome已崩溃”错误？
