inspect.lua not found in Sierra.

[dongahn]

@koning is getting an error as follows. It is from https://github.com/flux-framework/flux-core/blob/master/src/cmd/flux-wreck#L635. I think inspect.lua is not avail on Sierra systems.

I'm getting a new error:

Seems there is an installation issue: @grondo? For now, we will manually copy the file into our /usr/global installation.

Dong,

I confirmed that if we copy inspect.lua from the source tree at src/bindings/lua/inspect.lua into the install tree at share/lua/5.1/ then everything should be fine. Not sure why this isn't installed by default.

Oops, that is actually some leftover debug. The inspect module probably should not be used in installed code (it is in the src tree for debugging purposes). Glad you could work around it, but I'll add that to my list of issues to resolve.

[dongahn]

Thanks. In the meantime, I tagged this to our next release.
