Error on importing gym_pull

[shashank879]

I installed this using: 'pip3 install gym-pull', I assumed it is available on python3 Now on trying to import it using: 'import gym_pull', it gives an error.

In [1]: import gym_pull

Usage:   
  pip list [options]

no such option: --format

@shashank879 Are you using gym_pull in a virtualenv? See my pr #6

[shubhoghosal]

import gym_pull raises the following error: /bin/sh: pip3: command not found Traceback (most recent call last): File "", line 1, in File "/Users/shubhoghosal/anaconda3/lib/python3.6/site-packages/gym_pull/init.py", line 52, in from gym_pull.package import pull File "/Users/shubhoghosal/anaconda3/lib/python3.6/site-packages/gym_pull/package/init.py", line 4, in load_user_envs() File "/Users/shubhoghosal/anaconda3/lib/python3.6/site-packages/gym_pull/package/manager.py", line 33, in load_user_envs installed_packages = self._list_packages() File "/Users/shubhoghosal/anaconda3/lib/python3.6/site-packages/gym_pull/package/manager.py", line 186, in _list_packages with open(temp_file) as f: FileNotFoundError: [Errno 2] No such file or directory: '/var/folders/01/sk2yzmcd4cxby3nxt6z1c3jw0000gn/T/tmpvi0b4dug/pip_list.txt'

@absolutelyNoWarranty no

[schneblizoltan]

Same problem here. @shashank879 nothing changed after modifying the code

@schneblizoltan @shashank879 Try upgrading the pip you used to install gym-pull with pip install --upgrade pip. gym-pull is running a hard-coded shell command (pip list --format legacy) and really old versions of pip didn't have --format.
