尝试使用3.4进行开发构建(之前已在2.7中进行过管理)。 Python只是osx10.10上的anaconda安装。我可以得到
I:
但是当我尝试导入大熊猫时,我得到了:
import pandas as pd
Traceback (most recent call last):
File "<ipython-input-2-af55e7023913>", line 1, in <module>
import pandas as pd
File "/Users/Nick/github/pandas/pandas/__init__.py", line 13, in <module>
"extensions first.".format(module))
ImportError: C extension: 'hashtable' not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace' to build the C extensions first.
请注意,当我执行build_ext时,我得到以下(显然很好)输出:
pandas(master)$python setup.py build_ext --inplace

此外,如果我运行conda install pandas
,我可以安装pandas,但是我真的很喜欢代码开发的开发环境。

由于评论中的@chrisb,答案是运行python setup.py build_ext --inplace --force
。
答案 1 :(得分:1)
我用这个命令解决了重新安装pandas的问题:
conda install pandas
一切都运行正常,但我使用pip安装了一些东西并开始遇到问题。这解决了它。
