安装 plyr 包时出现问题

Question

我正在尝试安装 lyvi（命令行歌词查看器）这里。因此，在安装 plyr 的哪个依赖项时我遇到了该问题：

    Collecting plyr
    Downloading https://files.pythonhosted.org/packages/09/85/3b9928e2bfa38d4645c231dfc99c483af0a9e0da353af2cfd464645244f8/plyr-1.0.2.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
    File "<string>", line 1, in <module>
    File "/tmp/pip-build-atdqke/plyr/setup.py", line 3, in <module>
    from Cython.Distutils import build_ext
    ImportError: No module named Cython.Distutils

    ----------------------------------------
    Command "python setup.py egg_info" failed with error code 1 in 
    /tmp/pip-build-atdqke/plyr/

我先在 Google 上搜索，但没有帮助。我该怎么办？
