python3.6安装jupyter出现ipython与jupt

1、使用sudo install jupyter安装jupyter时，出现ipython与prompt-toolkit不兼容的问题，错误提示如下：

ipython 6.5.0 has requirement prompt-toolkit<2.0.0,>=1.0.15, but you'll have prompt-toolkit 2.0.7 which is incompatible.

2、使用sudo pip install prompt-toolkit==1.0.15安装对应版本，然而出现jupyter-console与prompt-toolkit不兼容的问题，错误提示如下：

jupyter-console 6.0.0 has requirement prompt-toolkit<2.1.0,>=2.0.0, but you'll have prompt-toolkit 1.0.15 which is incompatible.

处理方式：

使用sudo pip install jupyter-console=5.2.0降低jupyter-console的版本。测试有效。
