ERROR: UndefVarError occurred, including output in Weaved document

[likanzhan]

description

I have a simple mm.jmd file containing only one line of Julia code:

```julia
versioninfo()

But when I tried to weave the document with

weave("MM.jmd")

I got the following error

┌ Info: Weaving chunk 1 from line 1 └ progress = 0.0 ┌ Warning: ERROR: UndefVarError occurred, including output in Weaved document └ @ Weave ~/.julia/packages/Weave/74s70/src/run.jl:248 ┌ Info: Weaved all chunks └ progress = 1 [ Info: Report weaved to MM.html "/Users/lzhan/MM.html"

What could be the reason for this? 

Thanks,
Likan

since versioninfo is exported by InteractiveUtils , you need to do using InteractiveUtils in the document unless you weave(hoge; mod = Main) in REPL (InteractiveUtils is loaded into Main by default in REPL).
