错误 No module named 六

Question

I am new to Python/OpenCV.

I have the code below run in Python. But I got an error as shown below.

>>> from matplotlib import pyplot as plt

Traceback (most recent call last):
  File "<pyshell#20>", line 1, in <module>
    from matplotlib import pyplot as plt
  File "C:\Python27\lib\site-packages\matplotlib\__init__.py", line 105, in <module>
    import six
ImportError: No module named six

I followed what is being suggested in this post: ImportError: No module named six

I have downloaded six-1.8.0.tar.gz and unzip the file. I am wondering of is the next thing to do? I tried to run the six.py but I still got the same error.

Answer 1

You shouldn't need to download the tar.gz file. Instead run this at the command line (note, not the Python command line):

pip install six

And if that doesn't work, try:

easy_install six

Answer 2

I met the same problem (No module named six) when I tried to import nltk and to type easy_install six in cmd (Windows), it installed six for me.

And I imported nltk successfully.

Answer 3

Here's my experience when following this posts advice:

pip install six Defaulting to user installation because normal site-packages is not writeable Requirement already satisfied: six in /usr/lib/python3/dist-packages (1.16.0)

pip install --ignore-installed six Defaulting to user installation because normal site-packages is not writeable Collecting six Downloading six-1.16.0-py2.py3-none-any.whl (11 kB) Installing collected packages: six Successfully installed six-1.16.0

easy_install six easy_install: command not found

I hope this helps a lot of other people, because:

ModuleNotFoundError: No module named 'six'

This happens regardless if the module is installed or not.
