我最近需要更新SciPy并遇到错误，指出“环境不一致”。 this topic中对该问题进行了详细描述，但是我尝试了该线程中建议的所有解决方案，但均无济于事。我的工作和结果与this topic中OP中描述的工作和结果相同，不同之处在于，我也尝试恢复到原始主题中建议的以前的修订，以再次使用。但是，尽管更新过程似乎像第一篇文章末尾提到的this topic中的OP那样挂起，但它最终确实完成了，所以我有关于此错误的新信息。这是我终端的完整输出：

我每次尝试使用建议的here的不同方法时，都会感觉到“搜索不兼容的软件包”，我敢打赌无论我尝试什么，都会得到结果。但是，此命令终止需要花费几个小时，因此我无法对其进行测试。
sophros在this topic中的回答指出，这是一个已知的错误，但是除了说该错误尚未解决之外，没有其他解决方法。
那么，到目前为止，我已经尝试过什么方法来解决此问题？这个问题使我的研究不合时宜。
