需要帮助解决numpy 1.9.2和scipy 0.16.0上的这些错误。输出来自numpy.test(verbose=10)和scipy.test(verbose=10)，但我删除了所有行“ok”。

答案 0 :(得分：0)
终于解决了：
1）使用OpenBLAS构建解决方案路径 - 每个@ali_m解决方案：使用Compiling numpy with OpenBLAS integration
2）在本地系统上：两个问题是过时的cacerts（这台机器至少已有5年历史），以及需要更多磁盘空间的小问题（通过删除已知的旧文件解决）
3）尚未安装Cython，这可能与easy_install没有做好的原始问题有关。关于numpy和scipy的其他讨论已经提到cython对于直接从github下载的人来说是一个秘密的要求。因此，需要Cython才能完成numpy和scipy的安装。结果：numpy.test（）和scipy.test（）结果相对干净，更重要的是，scipy所需的import语句现在有效。
