指定 selenium-standalone 的 chromedriver 路径

Question

我正在尝试启动 selenium-standalone 服务器 (https://www.npmjs.com/package/selenium-standalone)，但它抛出了一个错误：

14:19:09 /usr/local/lib/node_modules/selenium-standalone/bin/selenium-standalone:54
14:19:09         throw err;
14:19:09               ^
14:19:09 Error: Missing /usr/local/lib/node_modules/selenium-standalone/.selenium/chromedriver/2.18-x64-chromedriver
14:19:09     at /usr/local/lib/node_modules/selenium-standalone/lib/check-paths-existence.js:15:20
14:19:09     at Object.cb [as oncomplete] (fs.js:169:19)
14:19:09 Build step 'Execute shell' marked build as failure

selenium 服务器正在路径中寻找 chromedriver

/usr/local/lib/node_modules/selenium-standalone/.selenium/chromedriver/2.18-x64-chromedriver

默认情况下。

是否可以在运行服务器时在命令行中指定 chromedriver 位置？比如：

selenium-standalone -Dwebdriver.chrome.driver=<path_to_chromedriver> start

你可能需要先安装它！

➜  ~ selenium-standalone install

selenium install:

selenium-standalone 提供此命令来帮助您下载和安装 chromedriver。此外，它还提供了设置和下载 selenium、chromedriver 和架构的不同选项的命令（我没有找到设置路径的命令）

# choose selenium version 
selenium-standalone install --version=2.45.0 --baseURL=https://selenium-release.storage.googleapis.com

# choose chrome driver version 
selenium-standalone install --drivers.chrome.version=2.15 --drivers.chrome.baseURL=https://chromedriver.storage.googleapis.com

# choose ie driver architecture 
selenium-standalone start --drivers.ie.arch=ia32 --drivers.ie.baseURL=https://selenium-release.storage.googleapis.com
