When you say python2, do you mean python3?

I have implemented second suggestion. https://github.com/game-ci/docker/issues/100#issuecomment-1023476647

I have implemented second suggestion. #100 (comment)

Much appreciated!

Would you mind updating the PR title and comments in the code to reflect the correct version please?

[dharmeshmp]

of course you can do any thing.

Done.

Did you build the image and check if it solves your problem?

Did you build the image and check if it solves your problem?

No, But I checked by adding ln -s /usr/bin/python3 /usr/bin/python in before_script stage of gitlab.

Ok good enough. Can you confirm that that worked?

Yes, It's working fine for me.

Hi, @dharmeshmp @webbertakken

this PR was based on my comment. After further review I would have recommended to just run the previous step for all targets :

-RUN echo "$module" | grep -q -v '\(webgl\|linux-il2cpp\)' \
-  && exit 0 \
-  || : \
-  && apt-get -q update \
+RUN apt-get -q update \
  && apt-get -q install -y --no-install-recommends --allow-downgrades \
    python \
    python-setuptools \
    build-essential \
    clang \
  && apt-get clean \
  && rm -rf /var/lib/apt/lists/*

As that already installs python. It would also remove additional complexity.

Or something like

+RUN apt-get -q install -y python
 RUN echo "$module" | grep -q -v '\(webgl\|linux-il2cpp\)' \
   && exit 0 \
   || : \
   && apt-get -q update \
   && apt-get -q install -y --no-install-recommends --allow-downgrades \
-    python \
     python-setuptools \
     build-essential \
     clang \
   && apt-get clean \
   && rm -rf /var/lib/apt/lists/*

( There's nothing wrong with the current implementation, I just noticed that python is being installed in a previous step. And for some reason I need it now also for win/mac/unix installs as Firebase is not filtering them in the latest version. So having python in all containers may be the fastest fix )
