环境说明

Window 7, Python 3.6.5

问题描述

在基于python来进行import之时,报出如下的错误:

>> from PIL import Image
Traceback (most recent call last):
  File "<ipython-input-12-0f6709e38f49>", line 1, in <module>
    from PIL import Image

  File "d:\ProgramData\Anaconda3\lib\site-packages\PIL\Image.py", line 58, in <module>
    from . import _imaging as core

ImportError: DLL load failed: 找不到指定的模块。

有时候,也会报出类似的错误:

>> from PIL import Image
Traceback (most recent call last):

  File "<ipython-input-13-0f6709e38f49>", line 1, in <module>
    from PIL import Image

ImportError: cannot import name 'Image'

问题分析

这类问题一般都是在安装library之时,安全不完整,或者安装的library被覆盖或者破坏了,所以无法知道相应的类库。

问题解决
