Question

我现在开始担心在低ram环境中使用厨师了。

我无法为python安装scipy的事实是非常不真实的。我必须等待一个错误..进入服务器，手动运行pip install scipy并重新运行chef solo然后切断工作。 RAM为1 gig服务器。

主厨......这笔交易怎么样？

python_package 'scipy' do
  version '0.18.1'
end

Answer 1

这个错误不是来自Chef，而是来自pip。厨师无法做到这一点。 SciPy和NumPy都是非常复杂的库，有许多花哨的C和Fortran（是的，真的）代码可以编译以使它们工作。我会看一下在构建机器上构建你的wheel文件，然后从那些文件安装。

Answer 2

试试pip install --no-cache-dir <pkgname>。
