最近，将电脑主机升级到ubuntu16.04，但是需要用到 python-imaging-tk，先是报错：

import PIL.ImageTk as ImageTk

ImportError: No module named ImageTk

参考网上的是pythonimaging-tk的包没有安装，所以

sudo apt-get install python-imaging-tk

但是报错

我自己也是小白，以前没遇到这个错，只能谷歌啦，但是没谷歌出什么东西，那我就改变检索方式：

python-imaging 3.1.2-0ubuntu1.1

找到一个网页https://launchpad.net/ubuntu/xenial/amd64/python-imaging/3.1.2-0ubuntu1.1，上面说：

PIL used to provide a PIL.pth file which allowed you to `import Image` but

this is deprecated. Use `from PIL import Image` now, or install this

compatibility package to temporarily get the old behavior back.

.

This compatibility package is built for Python 2 only.

网页还提供deb之类的下载，那我就尝试下载，发现不行，后面又想，我只缺tk模块呀，我单独下载安装就行啦，然后就

谷歌:

python-imaging-tk 3.1.2-0ubuntu1.1

找到这个网页https://ubuntu.pkgs.org/16.04/ubuntu-updates-main-amd64/python-pil.imagetk_3.1.2-0ubuntu1.1_amd64.deb.html

下载了：python-pil.imagetk_3.1.2-0ubuntu1.1_amd64.deb，系统要一致哦，

在终端：$ sudo dpkg -i python-pil.imagetk_3.1.2-0ubuntu1.1_amd64.deb Selecting previously unselected package python-pil.imagetk:amd64.

大功告成，其实我们有些在sudo apt-get install 找不到相应的版本可以自己安装哈！！！！！感觉自己又获得一个新技能，也从这里看出自己很low！！！！哈哈，没事没事，

每天进步一点点撒！！！
