Question

当我尝试为python构建包表-3.1.1时，这就是问题：

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)

* Found LZO 2 headers at ``/usr/local/include``, library at ``/usr/local/lib``.
* Skipping detection of LZO 1 since LZO 2 has already been found.
* Found bzip2 headers at ``/usr/local/include``, library at ``/usr/lib``.

Setting compiler flag '-msse2'

据我所知，它无法找到blosc库。我试图在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？谢谢。

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，这意味着你可能需要从源代码构建。 There are tarballs here，您必须关注their build instructions。
