Question

我想在我的mac上导入python3中的matplotlib。这给了我一个错误：

>>> import matplotlib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: bad magic number in 'matplotlib': b'\x03\xf3\r\n'

如果在stackoverflow上做了一些研究，我想2.7应该在sys.path中，对吧？我怎么能删除这个？还有其他建议吗？

>>> sys.path
['', '/usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/lib/python36.zip', '/usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/lib/python3.6', '/usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/site-packages', '/usr/local/opt/opencv/lib/python2.7/site-packages', '/usr/local/opt/opencv/lib/python3.6/site-packages']

编辑：有人刚提到这个：

sys.path = [x for x in sys.path if "python2.7" not in x]

运作良好。错误消失但出现了新的错误......

>>> import matplotlib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'matplotlib'

所以我尝试用

重新安装matplotlib

brew install matplotlib --with-python3

这种方法运作良好：

ImportError: 
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

Original error was: cannot import name multiarray
