UndefVarError: Server not defined

[MaximeBouton]

I am getting the following precompilation error on julia 1.1 with v0.6.0

julia> using Mux

Any idea on how to fix this? Thanks

At master version, Mux require both Http and Websockets. The last just switched to using the latest version of http. Did you just update?

In order to use one version of http, the best way of importing symbols to Mux may be through Websockets.

I just updated a few hours ago, I was getting the error when calling Blink.jl which depends on Mux.

It used to be that HTTP.Servers exported the symbol Server, but it looks like this is no longer the case in the new release. You can fix the problem by using a local version of Mux with ]develop Mux and then add the line using HTTP.Servers: Server at the beginning of ~/.julia/dev/Mux/src/server.jl. Once the problem is fixed in the upstream version, you can revert to it with ]free Mux.

Thanks this worked. It seems like #84 will fix it.

I have the same issue as OP and experience this on Unix. Mux is a dep of a package I'm developing and have submitted to METADATA.jl for registration. This issue is causing my package to fail to precompile. Is this something that can be fixed soon in the stable version?

[jpsamaroo]

As mentioned above, #84 will fix this, and I imagine a new version will be tagged promptly afterwards.

Fixed by #86
