Question

我按照建议here在小牛队上安装SciPy并运行：

brew install python3

pip3 install virtualenv nose

brew install numpy --with-python3
brew install scipy --with-python3

brew test numpy
brew test scipy

并没有遇到任何麻烦，直到最后一个命令产生：

Testing scipy
==> python -c import scipy; assert not scipy.test().failures
Python version 2.7.5 (default, Mar  9 2014, 22:15:05) [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)]
nose version 1.3.4
Traceback (most recent call last):

当我打开python3并输入import scipy; scipy.test()时，我会收到数百个错误和数十个失败的测试：

FAILED (KNOWNFAIL=276, SKIP=920, errors=326, failures=42)
<nose.result.TextTestResult run=16412 errors=326 failures=42>

我做错了什么？我以前安装了一堆软件（比如Python），然后卸载了所有东西并重新开始，但可能并没有这么干净。我可以在没有重新安装小牛的情况下挽救这个吗？

与此同时，Homebrew安装了GCC 4.9作为NumPy的依赖，但是这个输出表明我还在使用我用XCode安装的任何东西。这可能是一个单独的问题，但gcc -v给了我：

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix

我提到它的原因是我想知道我的系统是否造成了更大的问题。

Answer 1

这些错误是虚假的，可能会被忽略。这将在即将发布的scipy中修复。解释此问题的scipy问题在这里：https://github.com/scipy/scipy/issues/3853

Homebrew-python scipy公式现在应用scipy将在下一个版本中应用的相同修复程序;在brew update && brew reinstall scipy之后，brew test scipy将通过。

Answer 2

我使用Python 2.7遇到了同样的问题。我尝试了几件不同的事情：

创建名为＆＃34; gcc＆＃34;的软链接到/ usr / local / bin中的gcc-4.9这样当我执行which gcc
时，会显示酿造版本
sudo ln -s /usr/local/Cellar/gcc/4.9.2/bin/gcc-4.9 /usr/local/bin/gcc
告诉brew使用默认的FORTRAN标志：

brew install scipy --default-fortran-flags

我仍然遇到与您在回复brew test scipy时描述的错误相同的错误。运行numpy的测试套件没有产生任何错误。

小牛队：brew安装scipy - 好吧，brew测试scipy - 失败
