为python安装包表时出错

Question

这是我尝试为 python 构建包 tables-3.1.1 时的问题：

sudo python setup.py build_ext --inplace
dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid
* Using Python 2.7.2 (default, Oct 11 2012, 20:14:37)

我知道它找不到 blosc 库。我尝试在 python 中导入 blosc：

>>> import blosc
>>> help(blosc)

        ------
        TypeError
            If packed_array is not of type bytes or string.

        Examples
        --------

        >>> import numpy
        >>> a = numpy.arange(1e6)
        >>> parray = blosc.pack_array(a)
        >>> len(parray) < a.size*a.itemsize
        True
        >>> a2 = blosc.unpack_array(parray)
        >>> numpy.alltrue(a == a2)
        True

DATA
    __all__ = ['compress', 'compress_ptr', 'decompress', 'decompress_ptr',...
    __version__ = '1.2.4'

VERSION
    1.2.4

所以，python 可以找到 blosc 包。有人可以帮我解决安装包表的问题吗？ 先谢谢了。

您需要安装 blosc 开发库。如果您正在运行 CentOS 或 Fedora，请尝试 sudo yum install blosc-devel。对于 Ubuntu，我找不到类似的包，这意味着您可能必须从源代码构建。 There are tarballs here，你必须关注their build instructions。
