When using a Procfile from the default Python hellofly app, then adding in calls for sqlite3 to open a Sqlite DB from a mounted volume - the build fails due to missing ImportError: libsqlite3.so.0
in TOML:
[build]
builder = "paketobuildpacks/builder:base"
Is there a better buildpack to use that does include libsqlite-dev installed?
