Homebrewcask 在 Mac OS X 上做了一些应用程序链接魔术。显然它还不够好，因为 Selenium WebDriver 正在寻找 Firefox 可执行文件找不到它。以下是来自驱动 Selenium的RSpec测试运行的错误消息。Capybara

提示 Firefox 可执行文件位置的好方法是什么？

正如错误消息所说：您必须指定Selenium::WebDriver::Firefox::Binary.path自定义应用程序路径。

# in spec_helper.rb
require 'selenium/webdriver'

Selenium::WebDriver::Firefox::Binary.path =
  "/opt/homebrew-cask/Caskroom/Firefox/latest/Firefox.app/Contents/MacOS/firefox"

如果您不想接触测试框架，可以将 firefox 安装到/Applications（selenium 搜索的默认路径）以使其工作而无需设置Binary.path.

brew cask install --appdir="/Applications" firefox

我只是添加了 Selenium 的代码来专门寻找这个目录，而不需要设置它或更改 appdir。它将在 selenium-webdriver gem 2.49+ 中可用
