将brew安装的openblas链接到/usr/local

Question

我已经安装了R，它依次安装openblas -但没有安装到/usr/local：

==> openblas
openblas is keg-only, which means it was not symlinked into /usr/local,
because macOS provides BLAS and LAPACK in the Accelerate framework.

For compilers to find openblas you may need to set:
  export LDFLAGS="-L/usr/local/opt/openblas/lib"
  export CPPFLAGS="-I/usr/local/opt/openblas/include"

For pkg-config to find openblas you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openblas/lib/pkgconfig"

openblas的主要用例是R和scipy。后者的_no更多地支持Macos加速包:所以重定向到brew没有问题。前者无论如何都会使用这种方法:所以我认为这样做没有坏处。但是怎么做呢？

Answer 1

有两个步骤完成了这项工作：

• 通过brew卸载openblas： brew uninstall --ignore-dependencies openblas
• 重新安装R brew install R
• 手动创建指向/usr/local的符号链接： sudo ln -s /usr/local/opt/openblas /usr/local

现在我们有R了！
