"Could not read folder: test/intl" when having @rescript/core as a dependency

[cknitt]

When building my project, I get the following output

[1/7]📦 Building package tree...Could not read folder: test/intl...
[1/7] 📦 Built package tree in 0.01s
[2/7] 🕵️  Found source files in 0.00s
[3/7] 📝 Read compile state 0.03s
[4/7] 🧹 Cleaned 0/1503 0.00s
[5/7] 🧱 Parsed 0 source files in 0.00s
[6/7] ️🌴 Collected deps in 0.01s
[7/7] 🤺 ️Compiled 0 modules in 0.00s

Problems:

1. It is not clear in the output which package the message "Could not read folder: test/intl" applies to. Took me some searching to find out that it is @rescript/core.
2. test/intl is a dev source dir in @rescript/core and therefore should not be attempted to build when @rescript/core is used as a dependency (to my understanding).

@jfrolich - Any clue here? I'm not sure if we're correctly ignoring dev dependencies by the look of this 🤔

[jfrolich]

Yes we are ignoring it right now, perhaps compile them always. I think there was some issue with a package that added a clashing namespace in dev deps that broke our monorepo, so we turned it off.

Edit: oh wait, it's actually trying to compile it.. Hmm weird! Even more strange since we are successfully compiling @rescript/core

I'm also seeing this on a fresh project.

Tried backing down to 1.0.5 and was able to get a backtrace:
