Chef infra Chef无法安装scipy=MemoryError

我现在很担心在低ram环境中使用chef

我不能安装ScipyforPython的事实是不真实的。我必须等待一个错误..ssh进入服务器，手动运行pip install scipy并重新运行chef solo，然后服务器工作。RAM是服务器的1G

大厨，怎么回事

python_package 'scipy' do
  version '0.18.1'
end

那个错误不是来自厨师，而是来自皮普。厨师对此实在无能为力。SciPy和NumPy都是非常复杂的库，需要编译许多花哨的C和Fortran（是的，真的）代码才能使它们工作。我会考虑在构建机器上构建控制盘文件，然后从中安装。

尝试

pip安装--no cache dir
