ImportError: No module named shutil_get_terminal_size

自从安装anaconda之后，使用ipython的时候，老是报错

ImportError: No module named shutil_get_terminal_size

然后百度了一下让去改一下这个路径的文件内容

/Users/dushibing/anaconda/lib/python2.7/site-packages/IPython/utils/terminal.py, line 22, in <module>    from backports.shutil_get_terminal_size import get_terminal_size as _get_terminal_sizeImportError: No module named shutil_get_terminal_size

然后修改后跟新软件又遇到同样的有问题，然后决定跪求谷歌，找到一下方法：

conda config --add channels conda-forgeconda install backports.shutil_get_terminal_size

还是谷歌大法好啊，送上链接：
