我在尝试安装python库时遇到问题（https://pypi.python.org/pypi?name=py_find_1st&:action=display）;
我之前发过一篇关于它的帖子，但我没有得到解决问题的答案（AttributeError: 'MSVCCompiler' object has no attribute 'compiler' when trying to install a numpy extension），所以我想知道是否可以使用不同的方法来安装它
当我运行setup.py文件时，收到一条错误消息AttributeError: 'MSVCCompiler' object has no attribute 'compiler'。
我的计算机上安装了visual studio，安装了构建工具，cl被识别为命令。
我不太了解numpy扩展，但我想知道是否有安装库而不运行setup.py，因为它不能在我的计算机上运行，而且我有一个cpp文件在扩展文件夹中。
我真的很感激任何帮助，我发布了整个错误消息和setup.py代码：
编辑：我发现可以使用pip安装安装，我在cmd中收到相同的错误消息，其中一个红色的附加，我在帖子的底部添加了它
错误讯息：
