Python jenv.bash：没有这样的文件或目录

尝试在Python中运行代码时出现以下错误：

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

这是我的密码：

#!/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)

更改此行：

for comment in comments:

为此：

for comment in flat_comments:

comments

是一个生成器，您已经使用了它通过展平生成的所有注释。在那之后尝试迭代将不会产生任何结果

---

（您可能打算使用展平版本。）

“这行不通，您能解决这些错误吗？”什么错误？“我没有看到任何错误。@DeepSpace，请自己试着运行它。没有。”。你把收到的错误发出去怎么样？@DeepSpace你为什么这么粗鲁？我甚至没有收到任何错误。如果您没有收到任何错误，那么您希望我们解决哪些错误？现在它显示

ImportError:没有名为praw的模块。

此更改不可能导致该错误。那么为什么会导致该错误？该错误意味着您的Python环境中没有安装

praw

模块。也许你卸载了它，或者现在正在使用另一个virtualenv，等等。它已经安装好了。
