Actix-web: docker build error

[cheolgyu]

error: cannot produce proc-macro for actix-web-codegen v0.1.2 as the target x86_64-unknown-linux-musl does not support these crate types

FROM rust:alpine

[fafhrd91]

nothing can be done from actix-web side

[fafhrd91]

seems rust does not support proc-macro for musl target

maybe you can build it in Debian and then running in alpine.
