python - pandas 的开发版本给出 importerror : C extension: 'hashtable' not built on python 3. 4 (anaconda)

Question

尝试使用 3.4 进行开发构建(之前在 2.7 中进行过管理)。 Python 只是在 osx10.10 上安装了一个 anaconda。我可以得到

我:

• git 克隆 Pandas
• 运行 python setup.py build_ext --inplace(没有错误)
• 运行 python setup.py develop。

但是当我尝试导入 pandas 时，我得到:

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，但我真的想要一个用于代码开发的开发环境。

由于@chrisb 的评论，答案是运行 python setup.py build_ext --inplace --force。
