通过'sudo pip install -U selenium'更新Selenium失败

Question

我正试图通过shell命令更新selenium：

sudo pip install -U selenium

但我得到了这个输出：

    Exception:
Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/pip/basecommand.py", line 209, in main
    status = self.run(options, args)

    mkdir(name, mode)
OSError: [Errno 1] Operation not permitted: '/System/Library/Frameworks/Python.framework/Versions/2.7/selenium'

我不知道系统想用这句话告诉我什么：

O错误：[Erno 1]不允许操作：'/System/Library/Frameworks/Python.framework/Versions/2.7/selement'

有人熟悉这个问题吗？

也有同样的问题。

这对我很有效：去https://pypi.python.org/pypi/selenium#downloads并下载selenium-3.0.1.tar.gz.

然后：

tar zxvf selenium-3.0.1.tar.gz
cd selenium-3.0.1
sudo python setup.py install
