Restaurar PYTHONPATH após instalação de setup.py com PYTHONPATH

4

Eu executei este comando no Ubuntu 14.04 Linux ao tentar instalar um pacote:

export PYTHONPATH=/usr/local/lib/python2.7/ && sudo python setup.py install

O pacote que eu estava tentando instalar é link

Então muitas coisas relacionadas a Python deram errado desde então. Por exemplo, virtualenv não funciona mais, e este pacote não funciona:

link

source Downloads/dx-toolkit/environment
dx login
Traceback (most recent call last):
  File "/home/avilella/Downloads/dx-toolkit/bin/dx", line 7, in <module>
    from dxpy.scripts.dx import main
  File "/home/avilella/Downloads/dx-toolkit/share/dnanexus/lib/python2.7/site-packages/dxpy/__init__.py", line 143, in <module>
    from . import exceptions
  File "/home/avilella/Downloads/dx-toolkit/share/dnanexus/lib/python2.7/site-packages/dxpy/exceptions.py", line 211, in <module>
    network_exceptions = (requests.packages.urllib3.exceptions.ProtocolError,
AttributeError: 'module' object has no attribute 'packages'

Como faço para reverter isso para o estágio antes de executar esta linha de comando? Mesmo a partir de um novo terminal bash, agora ele não encontrará nenhuma das minhas outras bibliotecas python. Mesmo com um usuário Linux recém-criado no mesmo computador, os erros são os mesmos.

A questão relacionada não foi respondida: Corrigindo uma variável de ambiente PYTHONPATH quebrada

[EDITAR]

Eu não sei como reverter para a lista de pastas antes, mas presumo que tenha sido uma combinação de /usr/lib/python2.7 e /usr/local/lib/python2.7

Tentar virtualenv também falha agora:

virtualenv
Fatal Python error: Py_Initialize: Unable to get the locale encoding
  File "/usr/lib/python2.7/encodings/__init__.py", line 123
    raise CodecRegistryError,\
                            ^
SyntaxError: invalid syntax
Aborted (core dumped)

O python interativo funciona da mesma forma que eu tentei abaixo:

avilella@ubuntu14:~$ python
Python 2.7.6 (default, Oct 26 2016, 20:30:19) 
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> print "foo"
foo
>>> import urllib3
>>> 

Eu já passei pela pasta e tentei pip install e apt-get install python-${package} com isso:

ls /usr/local/lib/python2.7/dist-packages/*/ | grep -v egg | grep '\:' | tr ':' ' ' | grep -v dist-info | xargs -n1 basename  | while read i; do sudo pip install $i; done

Além disso:

ls /usr/local/lib/python2.7/dist-packages/*/ | grep -v egg | grep '\:' | tr ':' ' ' | grep -v dist-info | xargs -n1 basename  | while read i; do sudo apt-get install -y python-${i}; done

Mas ainda os mesmos problemas.

As solicitações de pacote estão lá:

Eu verifiquei uma versão funcional de uma VM diferente que eu tenho, onde tudo relacionado ao python funciona, e a pasta requests contém exatamente os mesmos arquivos.

Qualquer menção ao urllib no Linux que não funciona (abaixo) é a mesma que a do trabalho (mais abaixo), com 2 arquivos alterando sua data entre um e o outro:

Outra ferramenta de exemplo que não funciona mais é tosheets link :

tosheets

    from tosheets.tosheets import main
  File "/usr/local/lib/python2.7/dist-packages/tosheets/tosheets.py", line 27, in <module>
    from apiclient import discovery
ImportError: cannot import name discovery

Depois de fazer unset PYTHON , então:

>>> import sys
>>> sys.path
['', '/usr/local/lib/python2.7/dist-packages/multiqc-1.4dev-py2.7.egg', '/usr/lib/python2.7/dist-packages', '/usr/lib/pymodules/python2.7', '/home/avilella/Downloads/dx-toolkit/share/dnanexus/lib/python2.7/site-packages', '/home/avilella/Downloads/dx-toolkit/lib/python', '/home/avilella', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/home/avilella/.local/lib/python2.7/site-packages', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client']

unset PYTHON, o python3:

>>> import sys
>>> sys.path
['', '/home/avilella/Downloads/dx-toolkit/share/dnanexus/lib/python2.7/site-packages', '/home/avilella/Downloads/dx-toolkit/lib/python', '/home/avilella', '/usr/lib/python3.4', '/usr/lib/python3.4/plat-x86_64-linux-gnu', '/usr/lib/python3.4/lib-dynload', '/usr/local/lib/python3.4/dist-packages', '/usr/lib/python3/dist-packages']

O conteúdo de $ PYTHONPATH antes de fazer qualquer fonte está vazio.

Parece que estou preso neste ponto, sem saber como prosseguir.
