Error

Answer 1

Need to update node version.

Ubuntu (Linux)

Run this command to update node

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

after this close current terminal and open new one and run this command in PROJECT DIR

sudo npm install 
npm run dev

Answer 2

Just try to upgrade your current node version

Current stable 15.5.1

you can upgrade it using brew in Mac-OS case:

brew install nvm
nvm install 15
nvm use 15
