The error is caused by the old version of nodejs (usually lower than v6).

  • First install the latest stable version of nodejs or more recent version than you are using now.
# Using Ubuntu
curl -sL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
sudo apt-get install -y nodejs

# Using Debian, as root
curl -sL https://deb.nodesource.com/setup_lts.x | bash -
apt-get install -y nodejs

  • Then install yarn:
