Answer 1

Open Terminal and type:

sudo npm install -g nodemon

then

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

you will get an output similar to:

fs.inotify.max_user_watches=524288
fs.inotify.max_user_watches = 524288

After that your nodemon will perfectly work.

Answer 2

At first make sure that on your terminal, you are working on the correct project. you can check this by typing ls and then hit enter.

Then give the command to install nodemon. From the official website of nodemon, we found that, we have to write npm install -g nodemon

But if you fall in problem here, then write this-

sudo npm install -g nodemon
