报错：ModuleNotFoundError: No module named 'PIL'解决方法

运行时报错：

Traceback (most recent call last):
  File "***.py", line 5, in <module>
  from PIL import Image
  ModuleNotFoundError: No module named 'PIL'

运行安装pillow命令:

pip install pillow

如果运行时显示

Requirement already satisfied: pillow in /anaconda3/lib/python3.7/site-packages (5.4.1)

表示已经安装过了，这时可以先卸载，获取最新的pillow
运行卸载命令: pip uninstall pillow

然后再次运行安装命令
pip install pillow

easy_install Pillow

python3 -m pip install pillow

pip install -i https://pypi.douban.com/simple pillow

安装完毕，需要检查一下安装是否成功。
打开python后，输入 from PIL import Image
