Make dev.provision fails

Development

Hi,
I have an ubuntu machine which I try to run Edx on it.
When I run make dev.provision I get the following error:

++ docker-compose exec lms bash -c 'source /edx/app/edxapp/edxapp_env && cd /edx/app/edxapp/edx-platform && NO_PYTHON_UNINSTALL=1 paver install_prereqs'

SyntaxError: invalid syntax
Makefile:44: recipe for target 'dev.provision.run' failed
make: *** [dev.provision.run] Error 1

I’m using Python 3.7.
Any ideas on how to resolve this?

Thanks!

Hi @Edmond_Gam_Ze_Letova, welcome to the community!
What branch are you using for the devstack and edx-platform repositories? You can find them by running git rev-parse --abbrev-ref HEAD in your devstack and edx-platform directories.

It looks like you’re provisioning the devstack with Python 3, but running an older edx-platform version. The line from your error has been changed here, so it should be available from the Ironwood release.
