Spyder打不开，AttributeError: module ‘pandas‘ has no attribute ‘core‘

Spyder打不开了怎么办，先不要慌。在Anaconda Prompt 终端输入：spyder —new–instance

spyder --new-instance

 查看是什么原因打不开，我的是：

 抛出AttributeError: module ‘pandas’ has no attribute ‘core’

这时可以把pandas先卸载，进入spyder要紧。输入命令：

pip uninstall pandas

删掉之后发现可以打开spyder了，再把pandas装回来：

pip install pandas

运气好的话安装pandas一次成功不报错，但是我这里抛出

Installing collected packages: pytz, python–dateutil, pandas
  Attempting uninstall: pytz
    WARNING: Ignoring invalid distribution -atplotlib (c:usersgeanaconda3libsite-packages)
    Found existing installation: pytz 2016.10
ERROR: Cannot uninstall ‘pytz’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

显示pytz卸载不了，pytz是很多库的依赖项，想要卸载pytz可以在Anaconda3Libsite-packages下找到pytz-2016.6.1-py3.5.egg–info去手动卸载

 这时安装pandas就不会报错了

回到spyder

spyder是可以打开了，但是弹出这个弹窗

 重装nbconvert就好了

代码007普通
