How to fix node's "IOError: CRC check failed" error when installing Open edX ginkgo.1 release

During the installation process of Open edX ginkgo.1 release (native), you may encounter this error:

Don't panic, it just means that there's something wrong with the node prebuilt installation. And here are what you can do to fix it:

1. Clean up the node prebuilt directories:

$ sudo rm -rf /edx/app/edxapp/nodeenvs/edxapp/*

2. Install the node prebuilt manually:

$ sudo /edx/app/edxapp/venvs/edxapp/bin/nodeenv /edx/app/edxapp/nodeenvs/edxapp --node=6.11.1 --prebuilt --force

3. Re-run the installation script (e.g. this) and don't forget to append the --limit parameter:

...
cd /var/tmp/configuration/playbooks && sudo -E ansible-playbook -c local ./edx_sandbox.yml -i "localhost," $EXTRA_VARS "$@" --limit @/var/tmp/configuration/playbooks/edx_sanbox.retry

4. Enjoy
