The compiled binary should be also cached.

I find the compiled binary not be cached in ~/.npm/node-sass. So If the node-modules/ dir removed will download or compile again.

If the downloading pre-compiled binary failed(4.5.0), and the compiled binary not be cached in ~/.npm/node-sass/. I think it's better to cache the compiled binary as well.

[xzyfer]

I don't understand. If the binary fails to download how can we cache the downloaded binary?

[abcfy2]

Sorry, I mean that we should cache the compiled binary as well.

If downloading failed --> Compile binary from source. The compiled binary should be also cached, so that if we delete the node-modules/ directory, will not download or compile again.

[abcfy2]

Maybe just add a addition step after compile binary from source: copy compiled binary to ~/.npm/node-sass/${VERSION}.

darwin-x64-46_binding.node is to large, so the installing always be timeout.
