python – 由于dateutil的语法错误,Jupyter Notebook Anaconda无法打开

我正在尝试使用Anaconda导航器(在Mac OSX上)打开Jupyter Notebook,但我无法正常打开它.我一直在终端上收到这条消息.

File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/dateutil/parser.py", line 158
    l.append("%s=%s" % (attr, `value`))
                              ^
SyntaxError: invalid syntax

我试过检查我的默认版本的python,它说我的默认版本是python 3.6.然而,当我得到pip并尝试安装dateutil它说

pip install python-dateutil
Requirement already satisfied: python-dateutil in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python

我遇到麻烦,因为我的计算机上有多个版本的python.我能做什么？

解决方法:

我对anconda 4.5.1 python 3.6也有同样的问题.重新安装包解决了我的问题.

pip uninstall python-dateutil
pip install python-dateutil
