Estou tentando instalar o Anaconda na minha máquina Windows 7. Costumo usar o cygwin no meu trabalho de linha de comando e gostaria de gerenciar o Anaconda a partir daí. Eu trabalhei no instalador gráfico sem problemas e marquei as caixas necessárias para redefinir meu caminho padrão para esta instalação do python. Vou em frente para verificar onde está o python e, inicialmente, entendo isso ...

$ which python
/usr/bin/python

A partir daqui python funciona bem ...

$ python
Python 2.7.5 (default, Oct  2 2013, 22:34:09)
[GCC 4.8.1] on cygwin
Type "help", "copyright", "credits" or "license" for more information.

Mas estou tentando trabalhar com o anaconda, então só preciso redefinir meu caminho ...

$ export PATH=/cygdrive/c/anaconda:$PATH
$ which python
/cygdrive/c/anaconda/python

E agora eu devo estar pronto, mas quando tento entrar em python, ele simplesmente trava

$ python

Alguma idéia de por que isso pode estar acontecendo? retorno detalhado, abaixo ...

$ python -v

Outro problema (possivelmente relacionado) que estou tendo é a necessidade de redefinir o caminho toda vez que fecho / abro o cygwin. Digitei o seguinte texto em .bashrc e .profile para tentar definir o caminho permanentemente:

# Set path to python from anaconda install
export PATH=/cygdrive/c/anaconda:$PATH

Depois de abrir e fechar o cygwin, volto a:

$ which python
/usr/bin/python

Isso pode estar relacionado à configuração de determinadas variáveis de ambiente do sistema?
