我正在尝试在CentOS 6上升级setuptools，但遇到了这个问题:
$ sudo pip install setuptools --no-use-wheel --upgrade
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6
DEPRECATION: --no-use-wheel is deprecated and will be removed in the future. Please use --no-binary :all: instead.

有什么建议吗？我尝试使用pip手动卸载并重新安装，但这没有起作用。一旦setuptools被移除，pip就会抱怨缺少一个文件，无法继续安装。
