Snow Leopard 上的 Selenium 和 Python

Question

我正在尝试在 Snow Leopard 上使用带有 Selenium 的库存 Python (2.6.1)。作为 Python 的新手，我对自己做错的事情感到有点茫然，因为这个完全相同的过程在我的 ubuntu 机器上运行得很好：

1. sudo easy_install -U selenium
2. 使用 Firefox Selenium UI 创建一个简单的测试，并将其导出为 Python WebDriver (as mytest.py)
3. $ python mytest.py （这会导致：

此错误消息：

E

值得注意的一件事是，当我运行“sudo easy_install -U selenium”时，我确实收到警告：

Answer 1

首先检查您的 Firefox 二进制文件位置。它是否放置在此处：/Applications/Firefox.app/Contents/MacOS/firefox
？

有关详细信息，请查看此页面：http://code.google.com/p/selenium/wiki/FirefoxDriver

我对 Selenium 一无所知，但回溯表明它没有通往 Firefox 的可用路径。

您需要更改其配置/配置文件以为其提供 Firefox 可执行版本的路径。

目前的配置文件可能在 Linux 机器上具有 Firefox 的默认位置（这就是它在 Ubuntu 上运行的原因）。但在 OSX 上它不会位于这个位置。
