如何在 ubuntu 15.04 上升级 python setuptools > 12.2

Question

apt 包好像是 12.2

如果我运行 sudo pip install -U setuptools 该版本似乎仍然停留在 12.2

$ python
>>> import pkg_resources
>>> r = pkg_resources.require(["setuptools"])[0]
>>> print("setuptools version: %s" % r.version)
setuptools version: 12.2

刚刚注意到它不会覆盖 setuptools 的操作系统版本：

Answer 1

1. 删除存储库版本

   sudo apt-get remove python-setuptools
   

2. 如有必要，pip重新安装

   wget https://bootstrap.pypa.io/get-pip.py
   sudo -H python get-pip.py
   

3. setuptools通过安装pip

   sudo -H pip install -U pip setuptools
   

现在，再次开始测试

% python
Python 2.7.9 (default, Apr  2 2015, 15:33:21) 
[GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg_resources
>>> r = pkg_resources.require(["setuptools"])[0]
>>> print("setuptools version: %s" % r.version)
setuptools version: 18.3.2

笔记

安装依赖于python-setuptools或python-pip将带回这些包的任何包，因此您可能必须重复此过程！
