### Bug Description Same as the python plugin, when the meson plugin installs the files of a python or gjs based app, it cannot find the proper interpreter for them. To fix it, we have to manually fix the first line of those files. ### To Reproduce https://github.com/Sjoerd1993/Graphs/blob/main/snap/snapcraft.yaml#L88 This is an example snap, just remove this line and see the error. ### part yaml ```shell graphs: after: [ blueprint-compiler, numpy ] plugin: meson source: https://github.com/Sjoerd1993/Graphs.git meson-parameters: - --prefix=/snap/graphs/current/usr - --buildtype=release build-environment: - PYTHONPATH: $CRAFT_STAGE/usr/lib/python3/dist-packages:$PYTHONPATH - GI_TYPELIB_PATH: /snap/gnome-42-2204-sdk/current/usr/lib/$CRAFT_ARCH_TRIPLET/girepository-1.0:/snap/gnome-42-2204-sdk/current/usr/lib/girepository-1.0 organize: snap/graphs/current/usr: usr parse-info: [usr/share/appdata/se.sjoerd.Graphs.appdata.xml] ``` ### Relevant log output ```shell Logs can be found by installing the snap that'll build from the above given yaml. It'll fail to find the correct python interpreter. ```
