提问by Liondancer
I am not sure why I am getting this ImportError. queue.Queue()is in the documentation.

I am using it in a function like so:

错误：
Traceback (most recent call last):
File "./test_jabba.py", line 15, in <module>

File "/Users/bli1/Development/QE/TrinityTestFramework/poc/utils/tree_diff.py", line 5, in <module>
import queue
ImportError: No module named queue
Line 5 is import queue:
第 5 行是import queue：
#!/usr/bin/env python3
import sys # access to basic things like sys.argv
import os # access pathname utilities
import argparse # for command-line options parsing
import queue

A kinda standard cross py2-py3 compatible version:
一种标准的跨 py2-py3 兼容版本：
try:
import queue
except ImportError:
import Queue as queue

Replace #!/usr/bin/env python3with #!/usr/bin/python3
替换#!/usr/bin/env python3为#!/usr/bin/python3
If your env isn't set up correctly then #!/usr/bin/env python3may not work. If #!/usr/bin/python3gives the same error then try running /usr/bin/python3 --versionin your shell as a sanity check.
如果您的 env 设置不正确，则#!/usr/bin/env python3可能无法正常工作。如果#!/usr/bin/python3出现相同的错误/usr/bin/python3 --version，请尝试在您的 shell 中运行作为健全性检查。
If you don't get a sensible output from /usr/bin/python3 --versionthen you have odd installation of python 3 and I suggest installing it using your package manager (apt-get, yum, homebrewor whatever you prefer - this will probably fix the !#/usr/bin/envissue).
如果你没有得到合理的输出，/usr/bin/python3 --version那么你有奇怪的 python 3 安装，我建议使用你的包管理器安装它（apt-get, yum，homebrew或者你喜欢的任何东西 - 这可能会解决这个!#/usr/bin/env问题）。

Another way to avoid version problems is:
另一种避免版本问题的方法是：
import sys
is_py2 = sys.version[0] == '2'
if is_py2:
import Queue as queue
else:
import queue as queue

for ImportError: No module named 'Queue'in Python3, just replace the sentence "import Queue" with "import queue as Queue".
对于ImportError: No module named 'Queue'in Python3，只需将句子“ import Queue”替换为“ import queue as Queue”。
