Question

我知道有很多与此相关的问题，但是没有人为我解答，因为它们都使用Anaconda或Unix环境。

我安装了适用于Windows 7的Python 3.7.1，以及带有pip的pandas 0.23.4。因此，我只做import pandas as pd（通过jupyter和console），它吐出了

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

      5 

ImportError: cannot import name 'iNaT' from 'pandas._libs.tslib' (unknown location)

During handling of the above exception, another exception occurred:

     36 
     37 from datetime import datetime

ImportError: C extension: 'iNaT' from 'pandas._libs.tslib' (unknown location) not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace --force' to build the C extensions first.

谁能告诉我如何克服这个问题？错误消息的提示可能听起来很明显，但我只是不明白，所以如果有人一步一步地解释它，我将不胜感激。

按照从github克隆的熊猫上建议的setup.com过程进行操作。这需要pip --update的Cython。（site_packages / pandas中没有setup.com）。
然后，我卸载并重新安装了熊猫。高兴地报告已解决问题！

导入熊猫时C扩展错误
