导入matplotlib时遇到问题

Question

我在PyCharm4.5.3中导入matplotlib时遇到了麻烦

from pylab import *`

错误:

Traceback (most recent call last):
  File "/home/vera/PycharmProjects/COM/backend/17.08", line 10, in <module>

    from pylab import *

  File "/usr/lib/python3/dist-packages/pylab.py", line 1, in <module>

from matplotlib.pylab import *

  File "/usr/lib/python3/dist-packages/matplotlib/pylab.py", line 226, in <module>

import matplotlib.finance

  File "/usr/lib/python3/dist-packages/matplotlib/finance.py", line 21, in <module>

from matplotlib.dates import date2num

  File "/usr/lib/python3/dist-packages/matplotlib/dates.py", line 119, in <module>


     from dateutil.rrule import (rrule, MO, TU, WE, TH, FR, SA, SU, YEARLY,
      File "/usr/lib/python3/dist-packages/dateutil/rrule.py", line 55
        raise ValueError, "Can't create weekday with n == 0"
                    ^
SyntaxError: invalid syntax

Process finished with exit code 1

它在我安装PyCharm Community Edition之前就已经开始了.在专业版中它起作用了.但是在安装之后,程序甚至在PyCharm专业版中也被破坏了.

我做错了什么？

在anaconda虚拟环境中使用matplotlib时也遇到了同样的问题.将dateutil lib更新到最新版本对我有用:

pip install python-dateutil --upgrade

希望这可以帮助.
