ImportError:无法导入加载图像文件所需的Python映像库（PIL）

Question

我正在尝试运行facemorpher 1.0.1python包中的average.py程序。我已经创建了一个虚拟环境，其中openCV安装了homebrew，python 2.7安装了homebrew，可执行的frameworkpython在虚拟环境中构建了一个python框架cv。

运行average程序当前会提供此输出。

(cv) Francess-MacBook-Pro-2:face_morpher Megan$ frameworkpython facemorpher/averager.py --images=IMFDB_final/Ali/HelloBrother/images --out=average.png
Traceback (most recent call last):

    img, points = load_image_points(path, size)
File "facemorpher/averager.py", line 46, in load_image_points
    img = scipy.ndimage.imread(path)[..., :3]
 File "/Users/Megan/.virtualenvs/cv/lib/python2.7/site-packages/scipy/ndimage/io.py", line 25, in imread
raise ImportError("Could not import the Python Imaging Library (PIL)"
ImportError: Could not import the Python Imaging Library (PIL) required to load image files.  Please refer to http://pypi.python.org/pypi/PIL/ for installation instructions.

我可以安装枕头来修复这个错误吗？我应该在哪里安装我的枕头或枕头路径来修复这个错误？

通过在virtual env文件夹中执行pip install Pillow进行解析。现在返回到在OpenCV facemorpher 1.0.1 error: no image output, missing library?找到的错误
