Instalação maciça de python impedindo que o Yum seja executado no Redhat

Question

Eu estupidamente rm'd /usr/lib/python2.6 ao tentar instalar o 2.7.3 e agora meu sistema está extremamente danificado.

Não consigo executar o yum, o pip ou o easy_install.

O Yum não funciona:

[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 não funciona

[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 não funciona

[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

Eu tentei reinstalar manualmente setuptools novamente (espero que isso possa instalar o 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

O Python 2.7.3 e 2.6.6 funcionam bem no entanto.

Alguma idéia de como corrigir essa situação?

--------- Atualizar ------------ rpm -V yum produz muitos arquivos ausentes, como posso reinstalar esses arquivos?

'resolvido', limpando tudo e fazendo uma nova instalação. Lição aprendida! Não rm -rf coisas que você não entende: P

    

Answer 1

Limpa tudo e faz uma nova instalação. Demora muito tempo para reinstalar o yum, easy_install, pip para python2.6 e 2.7

    

Answer 2

pkg_resources é fornecido pelo Distribute ou setuptools Conforme anunciado na PyCon 2013, os projetos Distribute e setuptools foram reintegrados. O Distribute agora está obsoleto e você deve usar apenas as novas setuptools atuais. Tente isto:

curl -O https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
python ez_setup.py
