pandas - 我想在 JUPYTER 中使用 pandas2ri 但出现 tzlocal 问题？

Question

每次我尝试在 jupyter 中导入 pandas2ri，python 界面:

from rpy2.robjects import pandas2ri

我收到以下错误:

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-28-cc52694d111a> in <module>()
----> 1 from rpy2.robjects import pandas2ri

/Users/sondosayyash/anaconda/lib/python3.6/site-packages/rpy2/robjects/pandas2ri.py in <module>()
     21 import numpy
     22 import pytz
---> 23 import tzlocal
     24 import warnings
     25 

ModuleNotFoundError: No module named 'tzlocal'

我试着用

from dateutil.tz import tzlocal 

但这似乎并没有解决问题。

我已经安装了 tzlocal，它在我的电脑上。当我在ipython上导入pandas2ri时没有问题..只有在jupyter环境中调用时才会出现问题。

这是我尝试再次安装 tzlocal 时收到的消息:

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. 

Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.
Requirement already satisfied: tzlocal in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (1.5.1)
Requirement already satisfied: pytz in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from tzlocal) (2017.2)

Answer 1

在 Jupyter 中运行 rpy2 时，我遇到了类似的问题。我之前没有安装该软件包。我刚刚安装了软件包，错误就消失了。您可以尝试再次安装该软件包，看看它是否有助于解决您的问题。

pip install tzlocal

我必须补充一点，我使用的是 Python 3.6.8 而不是 2.7
