python-3.x - 导入 matplotlib 出现问题

Question

在 PyCharm4.5.3 中导入 matplotlib 时遇到问题

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

在我安装 PyCharm 社区版之前它可以工作。在专业版中它起作用了。但安装后，即使在 PyCharm 专业版中，程序也崩溃了。

我做错了什么？

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

pip install python-dateutil --upgrade

希望这会有所帮助。
