I wanted to install cython on my ubuntu 12.04 and I entered in the terminal 

```
sudo easy_install cython

```

in response, I get the following error:

```

sorry for the catalan in here but El fitxer o directori no existeix means that the file doesn't exist 

i think that i perhaps miss something or i don't know 

does anyone else have the same problem? or know how to install it correctly?
