如何在Amazon Web Service的Linux实例上的系统PATH中添加firefox？

这是一个幼稚的问题,但是如何将Firefox添加到Amazon Web Service Linux实例上的系统PATH？我应该澄清一下,我将firefox安装到了/ home / firefox而不是/usr/bin.谢谢！当我尝试加载firefox webdriver(导入硒后)时,当前出现以下错误：

>>> driver = webdriver.Firefox()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 64, in __init__
    self.binary = capabilities.get("binary") or FirefoxBinary()
  File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 47, in __init__
    self._start_cmd = self._get_firefox_start_cmd()
  File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 163, in _get_firefox_start_cmd
    " Please specify the firefox binary location or install firefox")
RuntimeError: Could not find firefox in your system PATH. Please specify the firefox binary location or install firefox

解决方法:

将以下内容添加到您的〜/ .profile中：

export PATH="$PATH:/home/firefox"

如果外壳是Bash,则转至〜/ .bashrc,或转至〜/ .bash_profile.
