Question

I installed PyDev in Eclipse on my Mac. Whenever I am writing code, it has only a few suggestions and is seemingly incomplete. For example, whenever I type ‘r’, it only suggests “raise()” and “return()”. However, all of the other functions that I would expect for it to suggest still execute at runtime.

This is the error:

Error connecting to python process.

Answer 1

i solved my Problem (was nearly the same):

i had

127.0.0.1 localhost

::1 localhost

written in my “hosts”-file:

HOW TO SOLVE:

1. open Terminal
2. sudo nano /etc/hosts
3. enter password
4. find both entries and comment them out with a “#” for example:
   
#127.0.0.1 localhost
#::1 localhost
5. CTRL+X
6. Y (on european Keyboard Z=Y)
7. ENTER

=> Solved
