我安装了C-Blosc库没有问题，但是当我尝试安装python-blosc并转到python setup.py build_ext --inplace --blosc="C:\\Program Files (x86)\\blosc"时，我收到链接错误。发生了什么事？
我有Windows 7，我正在尝试从这里https://github.com/Blosc在MSVC 2015中安装Python Blosc。

这是python-blosc的维护者。如评论中所述，进行pip install blosc将需要一个c编译器和python开发头文件。之所以如此，是因为python-blosc不能作为轮子使用（状态：2019年2月9日）。但是，您可以使用conda安装通过conda-forge构建的预编译二进制文件：
conda install -c conda-forge python-blosc
