pkgx: unexpected error cannot intersect: @1.6.4 && @1.5.4

I hit this too today, I would think it’s related, but otherwise I’ll open another issue. Tried to run pkgx psql in a folder with some packages already, and got:

$ env +psql

Output of env:

PKGX_POWDER=nodejs.org^18 git-scm.org pkgx.sh
PKGX_PKGENV=curl.se/ca-certs=2023.8.22 gnome.org/libxml2=2.11.4 tukaani.org/xz=5.4.5 unicode.org=71.1.0 openssl.org=1.1.1w zlib.net=1.3.0 gnu.org/gettext=0.21.1 curl.se=8.3.0 perl.org=5.38.0 libexpat.github.io=2.5.0 nodejs.org=18.18.0 npmjs.com=9.9.0 git-scm.org=2.42.0 pkgx.sh=1.1.4

pkgx.yaml:

dependencies:
  nodejs.org: 18
  npmjs.com: 9

basically this code needs to know if it’s going from one dev-env to another, rather than within a single dev-env. your test case looks something like this:

mkdir -p a/b a/c
echo -e "dependencies:\n  llvm.org: ^15" >a/pkgx.yml
echo -e "dependencies:\n  llvm.org: ^16" >a/b/pkgx.yml
cd a
dev
test "$(clang --version)" | grep "version 15"
cd b
test "$(clang --version)" | grep "version 16"
cd c
test "$(clang --version)" | grep "version 15"
cd b
test "$(clang --version)" | grep "version 16"
cd ..
test "$(clang --version)" | grep "version 15"
cd c
test "$(clang --version)" | grep "version 15"

i think.
