This is towards the end of the Purescript compiler build, but it happens to me when I try doing stack install language-javascript-0.7.0.0 on a completely fresh project as well.

For all I know, this error might be Windows 10 related. I've been running into crazy stack errors since yesterday and Haskell tooling is completely broken for me.

Any ideas why this could be happening?

This is a windows text encoding problem. I don't use Windows, but its my understanding that there is a windows specific way around this.

stack should be setting up the correct environment when it is building this package.

You are right. I actually figured it out myself just now. On a whim I changed my locale from Japanese to US and that managed to get the package install to go through. Thanks.

I also see this issue on OpenBSD.

Update: putting LANG=en_US.UTF-8 in front of the cabal install command fixed my issue. 🎉
