I have tried this on a macOS computer and there it works perfectly. Checking the permissions on /cnb/buildpacks/heroku_nodejs-engine/0.4.4/lib they are correct on macOS but wrong on my PixelBook.

The obvious difference is the storage driver of docker overlay2 (macOS) vs. btrfs.

Both machines have the exact same versions of heroku/buildpacks:18

Hello,

Same issue, also using btrfs.

Here is the prmission problem :

docker run --rm -it heroku/buildpacks:18 ls -ld /cnb/buildpacks/heroku_nodejs-npm/0.2.0/lib/

drw------- 1 root root 44 Oct 16 12:18 /cnb/buildpacks/heroku_nodejs-npm/0.2.0/lib/

[saez0pub]

On a overlay2 storage host:

docker run --rm -it heroku/buildpacks:18 ls -ld /cnb/buildpacks/heroku_nodejs-npm/0.2.0/lib/
drwxr-xr-x 3 root root 68 Oct 16 13:13 /cnb/buildpacks/heroku_nodejs-npm/0.2.0/lib/

Same here using zfs on sabayon (gentoo) amd64:

This seems to only happen to nodejs - other buildpacks work fine. Any update?
