No module named 'jupyter_core'

解决方法：

pip3 install --upgrade jupyter_core

pip3 install --upgrade notebook

pip3 install --upgrade lesscpy

pip3 install --upgrade jupyterthemes

又出现：No module named 'ipython_genutils.py3compat'

解决方法1：

pip install py3compat （依然没好）

解决方法2：

使用conda重新安装jupyter

conda install -c conda-forge jupyter

生成jupyter配置文件：

jupyter notebook --generate-config

ipython

from notebook.authimport passwd

passwd()  #创建密码并生成一串字符，以备后用

exit()

修改配置文件

vi~/.jupyter/jupyter_notebook_config.py

vi ~/.jupyter/jupyter_notebook_config.py

c.NotebookApp.notebook_dir=

c.NotebookApp.ip = '*'

c.NotebookApp.password= u'****#$cb358'#这里需要改为第（2）步你自己电脑上生成的密钥字符串

#c.NotebookApp.port =9001

jupyter notebook

jupyter 好了~
