升级权限被拒绝:如何在Mac OS X上升级pip？

Question

我是Mac OS X的新手.我想为python编程设置一个环境.我正在使用pip来管理第三方软件包.

我用easy_install安装了pip.

sudo easy_install pip

我试图将pip从6.1.0升级到6.1.1.但是,我的请求被拒绝了,我收到了以下消息.

$ pip install --upgrade pip
You are using pip version 6.1.0, however version 6.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting pip

  with open(path, 'wb') as f:
IOError: [Errno 13] Permission denied: '/usr/local/bin/pip'

看来我没有权限升级pip.我认为这不是缺乏依赖包的问题.我正在使用的OS X系统是OS X 10.10.3.我正在使用Python 2.7.9.

有人可以帮我解决这个问题吗？

您安装了它sudo easy_install pip,这是pip由root用户创建的.

升级时,您还应该使用:

sudo pip install --upgrade pip
