无法在 Intellij 中导入 matplotlib / Pycharm

Question

在 pyplot 的初始导入中，intellij 进行了折腾 - unable to load cexceptions:

#!/usr/bin/env python
import sys
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt   # This is the offender
import numpy as np
from numpy import *
import matplotlib.dates as mdt
import dateutil
from collections import namedtuple
 ..

这是输出：

我在 Yosemite 上使用最新的 IJ 14.1.4。

我无法直接解决。相反，我安装了 brew 版本 python 2.7.8.2 作为模块的 python SDK。

然而，这并不是故事的结局。在出现奇怪的错误后——比如抱怨输出路径相同——我做了 Invalidate Caches。又过了十五分钟就一切都好了
