error: multiple packages link to native library `ring-asm`, but a native library can be linked only once

[Christopher Andronikos]

Can't build with latest version of actix-web. Here is the error:

C:\Users\candronikos\Projects\project>cargo build
error: multiple packages link to native library `ring-asm`, but a native library can be linked only once

package `ring v0.13.2`

    ... which is depended on by `actix-web v0.7.3`
    ... which is depended on by `project v0.1.0 (file:///C:/Users/candronikos/Projects/project)`
links to native library `ring-asm`

package `ring v0.12.1`

    ... which is depended on by `actix-web v0.5.8`
    ... which is depended on by `sockjs v0.3.0`
    ... which is depended on by `project v0.1.0 (file:///C:/Users/candronikos/Projects/project)`
also links to native library `ring-asm`

Oh, sockjs currently should use 0.6, not 0.7...

Thanks for the tip, @DoumanAsh. I tried that already and got this issue, described in issue #5. If this the version I must use for my project, then this needs to be fixed first:

Uh, yeah sockjs needs update for new actix/actix-web
