python 2.7是否存在类似的内容?如果没有,我想实施它.我目前有一些使用audiere的东西,但它只是正弦波,所以听起来很可怕.有没有办法挂进midi钢琴或类似的东西 - 我正在使用Windows 7?是否有任何我可能不期望的实施步骤?
我想知道是否有人能帮助我解决这个问题.当我尝试python setup.py build(或pip install,或easy_install)时,会发生这种情况

libpng位于Library/Frameworks中,它位于<> includes(我用cpp -v检查)的搜索路径上,但它在那里作为libpng.framework,然后标题位于名为headers的子目录中.libpng.framework文件中还有几个版本的libpng.我也在运行64位python.任何想法如何进行?
