jenv.bash: No such file or directory

Question

I am getting the following error when trying to run my code in Python:

-bash: /usr/local/Cellar/jenv/0.2.0-201404260/libexec/../completions/jenv.bash: No such file or directory

Here is my code:

#!/usr/bin/python
# -*- coding: utf-8 -*-

import praw
import pdb
import re
import os

# Create the Reddit instance

UA = 'A Bot'
r = praw.Reddit(user_agent=UA)

REDDIT_USERNAME = '-snip-'
REDDIT_PASS = '-snip-'

r.set_oauth_app_info(client_id='-snip-',
                     client_secret='-snip-',
                     redirect_uri='http://127.0.0.1:65010/authorize_callback'
                     )

# and login

r.login(REDDIT_USERNAME, REDDIT_PASS)

subreddit = r.get_subreddit('all')
comments = subreddit.get_comments(limit=100)
flat_comments = praw.helpers.flatten_tree(comments)
already_done = set()
for comment in comments:
    if comment.body == 'Hello' and comment.id not in already_done:
        comment.reply(' world!')
        already_done.add(comment.id)

Here is the full console log of what happened when trying to run the Python code:

Change this line:

for comment in comments:

to this:

for comment in flat_comments:

comments is a generator, and you've already consumed all the comments it generates by flattening. Trying to iterate over it after that won't yield any results.

(You probably meant to use the flattened version anyway.)
