如何在Ubuntu 15.04上升级python setuptools> 12.2

apt软件包似乎是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

只是注意到它不会覆盖setuptools的操作系统版本：

1. 删除存储库版本

   sudo apt-get remove python-setuptools

2. 如有必要，请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

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

注意

安装任何依赖于python-setuptools或python-pip将这些软件包带回的软件包，因此您可能必须重复此过程！

AB提出的解决方案可能还不够：在最新版本的setuptools中，它pkg_resources是一个软件包，而以前它只是一个模块。

更新setuptools描述将路上留下一个陈旧的pkg_resources.py{,c}周围，导入时，这可能会导致以下错误setuptools：

AttributeError: 'module' object has no attribute 'packaging'

要删除它，请执行以下操作：

1. 找出过时的pkg_resources模块位于何处：

   $ python -c 'import pkg_resources; print(pkg_resources.__file__)'
   /usr/lib/python2.7/dist-packages/pkg_resources.pyc
   

2. 删除此文件及其.py文件：

   $ sudo rm /usr/lib/python2.7/dist-packages/pkg_resources.py*

警告

该文件可能是通过python-pkg-resources软件包安装的。因此，更新或重新安装此软件包将恢复旧模块！另请注意，您正在弄乱应该由所控制的文件apt。
