Question

我正在尝试升级CentOS 6上的setuptools并遇到这个问题：

$ 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？我试图用pip手动卸载和重新安装，但是没有用。删除setuptools后，pip抱怨文件丢失，无法继续安装。

追溯中的以下行 File "/usr/lib/python2.6/site-packages/pip-8.1.2-py2.6.egg/pip/utils/outdated.py", line 102, in pip_version_check

显示pip检查更新时引发的错误。作为一种解决方法，您可以通过将--disable-pip-version-check参数传递给pip来禁用此检查。

另请注意线路
Successfully installed setuptools
在输出中。考虑到上述两个观察结果，我认为忽视错误是安全的。

另外，我建议不要使用 sudo 和pip - 请参阅Is it acceptable & safe to run pip install under sudo?而是使用--user选项或virtualenv。

PIP无法升级setuptools
