当我尝试安装 2.7.3 时，我愚蠢地 rm'd /usr/lib/python2.6，现在我的系统严重混乱。
我无法运行 yum、pip 或 easy_install 。
Yum 不起作用：
[root@bobby tmp]# yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.7.3 (default, Dec 28 2012, 15:18:47)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
easy_install 不起作用
[root@bobby tmp]# easy_install
Traceback (most recent call last):
File "/usr/bin/easy_install", line 5, in <module>
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
pip 不起作用
[root@bobby tmp]# pip
Traceback (most recent call last):
File "/usr/bin/pip-python", line 5, in <module>
from pkg_resources import load_entry_point
ImportError: No module named pkg_resources
我再次尝试手动重新安装 setuptools（希望这可以安装 pkg_resources？？）
[root@bobby tmp]# sh setuptools-0.6c11-py2.7.egg
Traceback (most recent call last):
File "<string>", line 1, in <module>
zipimport.ZipImportError: can't decompress data; zlib not available
但是 Python 2.7.3 和 2.6.6 运行良好。
关于如何纠正这种情况有什么想法吗？
---------更新------------
rpm -V yum产生大量丢失的文件，我该如何重新安装这些文件？
[root@bobby python2.7]# rpm -V yum

通过清除所有内容并重新安装，已“解决”。吸取教训！不要 rm -rf 你不明白的东西 :P
答案1
删除所有内容并重新安装。为 python2.6 和 2.7 重新安装 yum、easy_install、pip 太耗时了
答案2
pkg_resources 由 Distribute 或 setuptools 提供。正如 PyCon 2013 上宣布的那样，Distribute 和 setuptools 项目已重新合并。Distribute 现已弃用，您应该只使用新的当前 setuptools。试试这个：
curl -O https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
python ez_setup.py
