Spyder如果打不开怎么办？别慌。Anaconda Prompt 终端输入：spyder --new-instance
spyder --new-instance看看为什么打不开，我的是:
Traceback (most recent call last): File "C:\Users\ge\Anaconda3\Scripts\spyder-script.py", line 5, in <module> sys.exit(spyder.app.start.main()) File "C:\Users\ge\Anaconda3\lib\site-packages\spyder\app\start.py", line 114, in main from spyder.app import mainwindow File "C:\Users\ge\Anaconda3\lib\site-packages\spyder\app\mainwindow.py", line 162, in <module> from spyder.utils.environ import WinUserEnvDialog File "C:\Users\ge\Anaconda3\lib\site-packages\spyder\utils\environ.py", line 20, in <module> from spyder.widgets.variableexplorer.collectionseditor import CollectionsEditor File "C:\Users\ge\Anaconda3\lib\site-packages\spyder\widgets\variableexplorer\collectionseditor.py", line 46, in <module> from spyder.widgets.variableexplorer.importwizard import ImportWizard File "C:\Users\ge\Anaconda3\lib\site-packages\spyder\widgets\variableexplorer\importwizard.py", line 26, in <module> import pandas as pd File "C:\Users\ge\Anaconda3\lib\site-packages\pandas\__init__.py", line 39, in <module> from pandas.core.api import * File "C:\Users\ge\Anaconda3\lib\site-packages\pandas\core\api.py", line 10, in <module> from pandas.core.groupby import Grouper File "C:\Users\ge\Anaconda3\lib\site-packages\pandas\core\groupby.py", line 40, in <module> from pandas.core.frame import DataFrame File "C:\Users\ge\Anaconda3\lib\site-packages\pandas\core\frame.py", line 72, in <module> from pandas.core.series import Series File "C:\Users\ge\Anaconda3\lib\site-packages\pandas\core\series.py", line 51, in <module> import pandas.core.strings as strings 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删除后，可以打开spyder了，再把pandas装回来：
pip install pandas运气好的话安装pandas成功不报错，但我在这里抛出
Installing collected packages: pytz, python-dateutil, pandas Attempting uninstall: pytz WARNING: Ignoring invalid distribution -atplotlib (c:\users\ge\anaconda3\lib\site-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.
